    Multiband Microwave Antennas {MULTIBAND MICROWAVE ANTENNA}
    [12] The present invention provides a substrate having at least one resonant conductor track structure, specially designed for mobile dual-band or multi-band telecommunication devices such as mobile and cellular telephones, as well as devices communicating according to the Bluetooth standard. It relates to a microwave antenna. The invention also relates to a printed circuit board with such an antenna and a telecommunication device with such an antenna.
    [13] Electromagnetic waves in the microwave region are used in mobile telecommunications for the transmission of information. The GSM mobile phone standard is used exclusively in Europe and most other countries of the world for cellular systems. Within this GSM standard, there are several frequency bands over which communication can take place, 880 to 960 MHz (so-called GSM900) on the one hand and 1710 to 1880 MHz (so-called GSM1800 or DCS) on the other. The third band, mainly used in the United States, uses frequencies from 1850 MHz to 1990 MHz (GSM1900 or PCS).
    [14] In general, the network service provider will provide its service only through one of those frequency bands. Increasingly, however, mobile phones operate in several frequency bands to provide mobile phones with an overall operational capability in any location, regardless of local circumstances and locally operated networks, and to protect a wide coverage area. The mobile phone is manufactured so that it can. Such telephones are also referred to as dual-band or multi-band mobile telephones. However, for this purpose there is a precondition that the antenna of such a mobile telephone must be able to transmit and receive electromagnetic waves in two or more respective frequency bands.
    [15] Another recently developed standard is a so-called spare frequency range from 2.4 GHz to 2.48 GHz, for example, so-called data exchange services between mobile telephones and other electronic devices such as computers, other mobile telephones and the like. Bluetooth standard (BT).
    [16] In addition, there is a strong trend in the market for miniaturization of devices. This, in turn, also creates a need to reduce components for mobile communication, i.e. electronic components, in size. The type of antenna used in today's mobile telephones can generally be wire antennas and has a substantial drawback in this regard because the antennas are relatively large. The antenna protruding from the mobile phone can be easily broken and undesirably visible to the user, and can also be positioned to interfere with the aesthetic design. In addition, undesired microwave radiation to the user by a mobile phone has been a hot topic of public debate. If the wire antenna protrudes from the mobile phone, most of the radiated power emitted can be absorbed by the user's head.
    [17] Surface mounting (via SMD, ie surface mount devices), that is, planar soldering of electronic components onto PCBs or printed circuit boards through wave soldering baths or reflow soldering processes is the latest digital It has become a common task in the technical implementation of electronic devices. However, the antennas used so far are not suitable for this mounting technique, since such antennas can often only be provided on the printed circuit board of the mobile phone through a special support, while at the same time the supply of electromagnetic power is also provided by pins or the like. This is only possible with special supply / support elements. This causes undesirable mounting steps, quality problems, and additional costs in production.
    [18] Efforts have been made to compromise these very different requirements and problems through optimized antenna designs. In particular, it should be considered here that the structure of the antenna is very strongly dependent on the application of the electronic device and the desired frequency range, rather than on the application of any other HF component, since the antenna is a resonant component that will be adapted to each operating frequency range. Because it is. In general, conventional wire antennas are used to transmit and receive desired information. If good radiation and reception conditions must be achieved for this type of antenna, certain physical lengths are absolutely necessary. The so-called λ / 2 dipole antenna (λ is the wavelength of the signal in the open space) has been specially made in this respect, which is formed of two wires each having a λ / 4 length and rotating up to 180 ° from each other. However, since such dipole antennas are too large for many applications, especially mobile telecommunications (the wavelength for the GSM900 range is, for example, approximately 32 cm), other antenna structures are used. An especially widely used antenna for the mobile telecommunication band is the so-called λ / 4 monopole, formed in a wire with a length of λ / 4. The radiation action of this antenna is acceptable and at the same time satisfies its physical length (approximately 8 cm for the GSM900). In addition, this type of antenna is characterized by large impedance and radiation bandwidth, so that the antenna can also be used in systems that require relatively large bandwidth, such as mobile phone systems, for example. In order to achieve an optimum power adaptation for 50 kHz, passive electrical adaptation is used for this type of antenna (similarly for most λ / 2 dipoles as well). This adaptation is generally formed by a combination of at least one coil and capacitance, which is appropriately sized to adapt the input impedance, rather than 50 Hz, to the connected 50 Hz component.
    [19] Another possibility is that larger dielectric constants ( Miniaturization of such an antenna is achieved by using a medium having Decrease by).
    [20] This type of antenna includes a solid block (substrate) made of dielectric material. Metal conductor tracks are printed on these blocks. Such conductor tracks can emit energy in the form of electromagnetic waves when they reach an electromagnetic resonance. The value of the resonant frequency depends on the size of the printed conductor track and the value of the dielectric constant of the block. Each resonant frequency value drops as the length of the conductor track increases and the value of the dielectric constant increases or decreases.
    [21] In order to achieve a high degree of miniaturization for the antenna, accordingly, a material with a high dielectric constant will be selected, and a mode with the lowest frequency will be selected from the resonance spectrum. This mode is designated as the base or basis mode, and the next higher mode for the resonant frequency is designated as the first harmonic. Such antennas are also referred to as printed wire antennas. The bandwidth of such a known antenna is sufficient in the case of a resonant frequency that lies within the area covered only by the GSM standard to achieve the maximum communicable area of one of the frequency bands of the GSM standard. Thus, the dual-band or multi-band applications described above are not possible here.
    [22] It is therefore an object of the present invention to provide a microwave antenna suitable for the above dual-band or multi-band applications and having the smallest possible size.
    [23] In addition, by SMD technology, through planar soldering, contact with the conductor track is possible-as with other components of the printed circuit board-without the need for additional support (pins) for the supply of electromagnetic power. There will be provided a microwave antenna, which can be mounted to such a degree.
    [24] The present invention should also provide a microwave antenna for that purpose so that the resonant frequency can be individually adjusted without changing the basic antenna design so that the resonant frequency can be tailored to a given structural situation.
    [25] Finally, a microwave antenna will be provided that can also be individually adapted to structural situations in which the input impedance is defined.
    [26] To achieve this object, a microwave antenna is provided with a substrate having at least one resonant conductor track structure, which according to claim 1, wherein the first conductor track structure extends substantially in a meandering shape. At least a first conductor portion and a second conductor portion, the two conductor portions determining a frequency interval between the first resonant frequency of the fundamental mode and the second resonant frequency for the first harmonic of the fundamental mode and the two conductor portions. It is characterized by having a gap that can be adjusted by changing the distance between.
    [27] A particular advantage of this solution is that the frequency of the fundamental mode can be adjusted by the total length of the conductor track structure, and the frequency spacing between the fundamental mode and the first harmonic can be adjusted through the interval so that the antenna can be tuned to the GSM900 and GSM 1800 bands. Can be operated as a dual-band antenna.
    [28] The dependent claims describe other advantageous embodiments of the invention.
    [29] The embodiments of the dependent claims 2 and 3 have the advantage that the frequency spacing can be adjusted even better.
    [30] The embodiment of claim 4 has the advantage that it is possible to surface mount the antenna along with other components on a printed circuit board, thereby making manufacturing substantially simpler and accelerated.
    [31] The embodiment of claim 5 makes it possible to independently adjust the frequency of the first harmonic or fundamental mode without the other of these two frequencies being significantly affected.
    [32] The embodiment of claim 6 has the advantage that the antenna can even operate in three frequency bands and at the same time has the advantage that it is possible to supply via a junction feed terminal according to claim 7.
    [33] Tuning of each resonant frequency of such a three-band antenna can be implemented in the embodiments of claims 8 and 9.

    [35] The antenna described is basically a printed wire antenna with conductor tracks provided on the substrate. Thus, such an antenna is, in principle, a wire antenna without a metal surface on the back of the substrate operating at a reference potential as opposed to a microstrip antenna.
    [36] Embodiments to be described below include substrates consisting of substantially rectangular blocks, wherein the height of the blocks is approximately 3 to 10 smaller than the length or width. Thus, the following description will refer to the upper and lower (larger) surfaces of the substrate shown in the figures as the first upper and second lower surfaces, while surfaces perpendicular to the surface are designated as the first to fourth sides. Will be.
    [37] Alternatively, however, it is also possible to select for the substrate a geometrical shape, such as a cylindrical shape, which is provided in the same resonant conductor track structure as, for example, the following spiral course, which is not in the form of a rectangular block.
    [38] The substrate can be made by inserting ceramic powder into the polymer matrix, Dielectric constant of and / or It may have a transmittance of.
    [39] More specifically, the antenna of FIG. 1 includes a substrate 1 on which first conductor track structures 31 to 39 are provided on a surface, which structure is provided through a feed terminal 40. Soldering portions 21 to 25, also designated as footprints, are present on the lower surface of the substrate, by which the substrate 1 is soldered to the printed circuit board PCB through surface mounting SMD. Can be.
    [40] The conductor track structure is formed by a plurality of individual conductor portions printed on the substrate. More specifically, the individual conductor portions are first and second portions 31, 32, and the first and second portions 31, 32 are substantially parallel to the length of the upper surface of the substrate 1. Extending side by side, the second portion 32 is incorporated into the rectangular surface 39.
    [41] The third part 33, which also extends in the longitudinal direction of the substrate 1, is considerably shorter than the preceding part. In addition to the first and second portions 31 and 32, the first and third portions 31 and 33 also have, at their ends, the fourth and fifth portions 34 extending in the width direction of the substrate 1. Each connected at 35 creates a meandering arrangement of these parts 31 to 35.
    [42] On the first side 11 of the substrate shown on the right side of FIG. 1, a sixth conductor making a connection between the seventh portion 37 and the third portion 33 lying on the lower surface of the substrate along the longitudinal direction of the substrate. Part 36 is present. This seventh portion 37 extends substantially parallel to the first and second portions 31 and 32 in the direction of the foremost (second) side 12 of the substrate, as shown in FIG. It has a length that substantially coincides with the length of the portion 33, wherein the third portion 33 lies above the seventh portion 37 on the upper surface of the substrate 1 in a vertical projection. The eighth portion 38 extending in the width direction of the substrate is connected to the seventh portion 37 and merged into the feed terminal 40 in the form of a metal pad.
    [43] Electromagnetic energy is connected to the antenna via a feed terminal 40 placed on the lower surface of the substrate 1. To this end, the feed terminals are soldered onto the corresponding conductor tracks on the printed circuit boards (FIGS. 4 and 5) in the surface mounting process. The feed terminal (or connecting means) need not necessarily be placed on the second side 12 of the substrate 1.
    [44] The feed terminal 40 is merged into the first conductor segment 41 at the second side 12, which will be described in more detail below.
    [45] The resonant frequency of this antenna can be adjusted in a known manner by the total length of the printed conductor track structure. As an example for the application of this embodiment in a dual-mode mobile phone, the lowest resonant frequency, ie the base mode, is adjusted to correspond to the lowest of the two frequencies at which the antenna is to be operated. The higher resonant frequency, ie the first harmonic, must then be adjusted to correspond to the higher operating frequency. This means that the frequency interval from the first harmonic to the fundamental mode should be adjusted according to the interval between the two operating frequencies, while the frequency of the fundamental mode will remain substantially unchanged.
    [46] This is achieved through two mutually independent means for the antenna according to the invention.
    [47] On the one hand, the spacing of the first harmonics for the fundamental mode can be changed by changing the spacing between the first and second conductor portions 31, 32. To this end, the lengths of the fourth and fifth conductor portions 34, 35 are appropriately increased or decreased. Alternatively, particularly in the case of the built-in antennas, one or two conductor portions 31 and 32 are partly removed along their mutually opposite ends via the laser beam, thereby reducing the spacing through laser trimming. It is also possible to increase.
    [48] On the other hand, this frequency shift can also be achieved by changing the length of the seventh conductor portion 37 at the bottom surface of the substrate 1.
    [49] The frequency spacing is qualitatively reduced by shortening the seventh conductor portion 37 as well as increasing the spacing between the first and second conductor portions 31, 32.
    [50] In a possible embodiment of this first antenna, the size of the substrate 1 is approximately 17 x 11 x 2.0 mm 3. The material selected for the substrate 1 is It has a dielectric constant of and a tanδ value of 1.17 × 10 -4 . This corresponds almost to the HF characteristics of commercial NP0-K17 ceramic materials (Ca 0.05 Mg 0.95 Ti 0.3 ceramics). The printed conductor tracks were made of silver paste and had a total length of approximately 55.61 mm. The width of the conductor portion is approximately 0.75 mm, while the size of the rectangular metal surface 39 at the end of the second conductor portion 32 is approximately 11.0 x 4.5 mm 2 .
    [51] For example, for the length of the seventh conductor portion 37, which is 6.25 mm, the frequency spacing of the first harmonic for the fundamental mode is approximately 820 MHz. From the length of this conductor portion 37, which has a spacing of 873 MHz, is 5.75 mm. Occurs.
    [52] With respect to the length of the fourth conductor portion 34 and hence the spacing between the first and second conductor portions 31 and 32 that are 3.0 mm, the frequency interval is 900 MHz, whereas the frequency interval of 878 MHz This results from the length of the fourth conductor portion 34 which is 2.5 mm. Accordingly, such antennas are suitable for dual-band operation in the GSM900 and GSM1800 frequency bands.
    [53] FIG. 2 shows the ratio R (reflection coefficient) between the power reflected from the antenna and the power supplied to the antenna according to the frequency F measured in MHz units in the supply line 40 of this antenna. It is evident that two resonances are located in GSM900 and GSM1800, in addition the band is also sufficient for effective operation in both frequencies.
    [54] In addition to the advantages of possible surface mount (SMD) presented for all embodiments, this embodiment has a substantial additional advantage that the frequency spacing from the first harmonic to the fundamental mode can be adjusted as desired.
    [55] 3 shows a second embodiment of the present invention. In this figure, the same or similar elements and components are given the same reference numerals as in FIG. 1. In this regard reference is made to the description of FIG. 1 accordingly, only the differences will be discussed below.
    [56] In this embodiment of the first conductor track structure according to FIG. 1, a second conductor segment 42 in the form of a stub line is present in addition to the first conductor segment 41, which stub line is present. It is present on the upper surface of the substrate 1 and extends from the first conductor portion 31 in the direction toward the first side 11 of the substrate.
    [57] In the fundamental mode the resonant frequency of the antenna can be adjusted by changing the length of the first conductor segment 41 in the direction towards the upper surface of the substrate 1. The frequency of the first harmonic is only slightly affected by such adjustments. In addition, the frequency of the first harmonic can be adjusted by changing the length of the second conductor segment 42 in the direction of the first side 11. This adjustment only slightly affects the frequency in the fundamental mode this time.
    [58] The effect of this adjustment of the resonant frequency in the fundamental mode is the latter because the field strength is relatively large for the fundamental mode in the region of the first conductor segment 41 but relatively small for the first harmonic in the region of the segment 41. Is based on the fact that it is still substantially unaffected. Thus, the length extension of the first conductor segment 41 induces a strong influence on the resonant frequency in the fundamental mode. The frequency of the first harmonic is then substantially still unaffected at that time.
    [59] In a similar manner, the second conductor segment 42 moves the harmonics in frequency by increasing or decreasing the volume through a strong electric field with respect to the first harmonic, while the fundamental mode only produces a small field strength at the location of the problem. It is designed and positioned so that it is substantially still unaffected.
    [60] The basic advantage of this embodiment is that the frequencies of the fundamental mode and the first harmonic can be adjusted independently of each other. In addition, the change in the antenna design required for this is only small, and the antenna works completely also without such a change. In order to adequately implement the adaptation to the actual structural design, a first, which is relatively easy to perform, even in the merged state, for example by means of laser trimming, i. It is sufficient just to change the size of the conductor segment 41 or the second conductor segment 42.
    [61] In a practical implementation of this second antenna, the size of the substrate 1 is approximately 17 x 11 x 2.0 GHz. The material selected for the substrate 1 is It has a dielectric constant of and a tanδ value of 1.17 × 10 -4 . This corresponds almost to the high-frequency characteristics of commercially available NP0-K21 ceramic materials. The printed conductor tracks were made of silver paste and had a total length of approximately 55.61 mm. The width of the conductor portion is approximately 0.75 mm, while the size of the rectangular metal surface 39 at the end of the second conductor portion 32 is approximately 11.0 x 4.5 mm 2 .
    [62] For the length of the first conductor segment 41, which is 1.5 mm in the direction towards the upper surface of the substrate, the frequency of the fundamental mode is approximately 928 MHz. By reducing the length to 0.4 mm, the frequency of the fundamental mode is 975 MHz. This represents a change of 47 MHz, while at the same time the frequency of the first harmonic is only changed by 9 MHz.
    [63] Likewise, if the length of the second conductor segment 42 is approximately 0.75 mm, the frequency of the first harmonic, which is approximately 1828 MHz, is obtained. Increasing its length to 3.75 mm provides a resonant frequency of approximately 1800 MHz. This is 28 MHz changed, while the frequency of the basic mode then has a shift of less than 1 MHz.
    [64] 4 schematically shows a printed circuit board (PCB) 100, from which the antenna 110 is combined with other components in the regions 120 and 130 of the printed circuit board 100. Was provided by This allows not only the feed terminal 40 to be connected to the corresponding soldering point on the substrate 100 but also to planar soldering in a wave solder bath or reflow soldering process via the soldering points 21-25. Is done through. Thus, one of the electrical connections created is an electrical connection between the feed terminal 40 and the conductor track 111 on the printed circuit board 100, through which the electromagnetic energy to be radiated is provided.
    [65] FIG. 5 shows a third embodiment of an antenna 110 according to the invention which is shown mounted on a printed circuit board 100. Here too, the same or similar elements are provided with the same reference numerals as in FIG. 4, so that repeated descriptions thereof may be omitted and only the differences will be described.
    [66] In this third embodiment, a second conductor track structure 61, 62 is additionally provided on the substrate 1 to the first conductor track structure 51, 52, wherein the second structure is a combined feed terminal 40. And is supplied via the combined feed terminal 45. In this embodiment the feed terminal 40 is located on the elongated first side 11 of the substrate 1 and soldered to the conductor track 111.
    [67] A feed line 45 is connected to the feed terminal 40, which extends along the periphery of the substrate 1 at the first, second, and third side surfaces 11, 12, 13, It then extends in the direction of the upper first surface of the substrate on about the third side 13 on the opposite side, approximately in the middle of the side length, to feed the first metal conductor track structure present on this upper surface. This structure is in the form of a first conductor portion 51 extending in a direction towards the first side 11 and a substantially rectangular first metal surface or patch 52 connected to the end of the first conductor portion. And a second conductor portion.
    [68] The first tuning stub line 53 is also opposed to the feed line 45 in the form of a second substantially rectangular metal surface from the feed terminal 40 at the first side 11 of the substrate 1. Direction, and is designed to tune the first metal conductor track structures 50, 51 to the first operating frequency band. In addition, the second tuning stub line 54 for the second operating frequency band extends along the third and fourth side surfaces 13, 14 of the substrate and is connected to the end of the feed line 45.
    [69] The feed line 45 feeds the second metal conductor track structures 61 and 62 at approximately half the length of the second side 12, the second metal conductor track structures 61 and 62 into the third frequency band. It is provided for operating the antenna. This latter structure comprises a substantially rectangular third metal surface or patch that is connected to the end of the third conductor portion 61 as well as the third conductor portion 61 extending in the direction towards the fourth side 14. 62). If so desired, tuning stub lines may also be printed for this second conductor track structure 61, 62, but not for the present embodiment.
    [70] In this embodiment the first conductor track structures 51 and 52 serve to tune and operate the antennas in the GSM900 and GSM1800 bands, while the second conductor track structures 61 and 62 are 2480 MHz BT (Bluetooth). It is designed to operate the antenna in the band.
    [71] The position and length of the first conductor portion 51 and the first metal surface 52 on the upper surface of the substrate 1 here are substantially equal to the impedance adaptation to 50 Hz as well as the position of the resonant frequency relative to each other. Decide These frequencies are selected such that the fundamental mode is in the GSM900 band and the first harmonic is in the GSM1800 band (as in the first and second embodiments of the antenna). The tuning of the two resonant frequencies and impedance adaptation to suit the context of the joint structure is also dependent on, for example, the type of housing and the influence of the housing on the resonant action, here via two tuning stub lines 53, 54. . Shortening the length of these stub lines (eg, via laser trimming) leads to the shift of the two resonant frequencies to higher values, whereby a more stringent connection of microwave energy can be achieved at the same time.
    [72] Proper positioning and sizing of the third metal surface 62 leads to tuning the resonant frequency of this structure to the BT band, while certainly other frequency bands (eg PCS1900 or UMTS) are also available for alternative applications. Can be covered.
    [73] A particular advantage of this embodiment is that, in addition to the possibility of surface mounting, significantly smaller size, and other advantages mentioned above, three-band operation is possible in a correspondingly designed mobile phone device via this antenna.
    [74] In a particular implementation of this third embodiment of the antenna, the substrate 1 has a size of 15 x 10 x 3 dB. The resonant frequency of this antenna is 943 MHz for the GSM band, 1814 MHz for the GSM1800 (DCS), and 2480 MHz for the BT band. The reflection coefficient curve R shown in FIG. 6 as a function of frequency F is sufficient to operate the antenna in three bands. It has also been confirmed that the same resonant frequency can also be achieved through a substrate having a size of 13 × 10 × 2 kHz, whereby a volume reduction of 42.2% is achieved compared to the substrate mentioned earlier.
    [75] As mentioned above, the present invention has the effect of providing a microwave antenna suitable for dual-band or multi-band applications and having the smallest possible size.
