    BI-MODAL GUIDANCE POWER COMPUTER DIVISOR
    COOL
    FIELD OF THE INVENTION
    The present invention pertains to the field of waveguide devices, and in particular to the field of splitters! Bi-modal waveguide power combiners, and with beam confounding networks.
    BACKGROUND OF THE INVENTION
    A bi-modal power splitter / combiner with two output ports is a device that is an essential part of an antenna power system, and is preferably used to separate / combine into: an electromagnetic input / output signal, which propagates at least two orthogonally polarized modes, in / / two electromagnetic output / input signals, each of which propagates at least two orthogonally polarized modes. In practice it is a device with three physical ports in waveguide (1 input port and 2 output ports, or vice versa), where each physical port transmits at least two electromagnetic signals oriented orthogonally. This means that this structure of three physical ports has at least six electrical ports.
    Currently, there are different bi-modal power splitters / combiners, all of them comprising three physical ports: F. Alessandri el al. "A new cJass 01 dual-mode directional couplers lor compact dual-polarization beam-forming networks", IEEE Microwave. and Guided Wave Letters, vol. 7, no. 9, Sept. 1997; F. Alessandri e / al. "Enhanced dual polariza / ion direc / ional coupler for dual polariza / ion beam forming networks", IEEE MIT..s Int. Microw. Symp Digest, Boston, USA, June 2000; or N.JG. Fonsecaet al. "Design 01 a waveguide dual-mode three-way power
    divider jor dual-polarize / ion beamjorming networks al Ka-band ", IEEE Anlennas and
    Prop. Society Inl. Symp (APSURSI), Orlando, USA, July 2013.
    These structures use the concept of 'directional coupling between two waveguides of
    5 square section to form a power splitter / combiner with three physical ports. Said square bi-modal waveguides are coupled by aligned rectangular grooves that are designed to allow the passage of the electromagnetic signal from a main guide to a secondary guide. However, the bandwidth of such structures depends mainly on the number of sections of
    10, that is, the number of rectangular grooves and, therefore, the total length of the power divider. This implies that the fractional bandwidth that is obtained for these topologies does not exceed 10%, due to limitations in size and manufacturing cost, which is critical in modern antenna beam confronting networks.
    In addition, and because these structures have only three physical ports, it is necessary to chain similar structures such that the splitter / combiner has different N levels. Only from this phonoa, it is possible to obtain a number of outputs (or enlIadas, in the case of the combiner) equal to ZN, However, in this way the total length of the antenna feed system is drastically increased
    20 Therefore, an improved bi-modal power splitter would be advantageous and, in particular, one that had division into at least four ports, good electromagnetic characteristics, compact size, the appropriate topology to obtain, through a dedicated interconnection of N -nivelc :: s, a large number of output ports, and a
    25 easy manufacturing.

    DETAILED DESCRIPTION OF THE INVENTION
    In this text, the term "understands" and its variants should not be understood in the exclusive sense, that is, these terms are not intended to exclude other technical characteristics, additives, components or steps.
    In addition, the terms "approximately." "substantially". "around", "ones", etc. they should be understood as indicating values close to those mentioned by those tenors, since due to calculation or measurement errors, it is impossible to achieve those values with complete accuracy.
    The following preferred embodiments are provided by way of illustration, and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention.
    The proposed bi-modal splitter / combiner aims to: 1) separate an electromagnetic signal into at least four electromagnetic signals; and 2) combine into one
    electromagnetic signal, at least four electromagnetic signals, in such a way that each electromagnetic signal mentioned propagates at least two orthogonal modes polarized linearly or circularly. The term `` bi-modal '' refers hereinafter to the capacity of certain hollow waveguides, such as circular waveguides or
    5 square, to propagate electromagnetic signals while having two orthogonal polarizations related to its fundamental propagation mode.
    To simplify the drafting of this report, and because the device of the invention has a bi-directional operation, on certain occasions we will refer to it only as a divisor, the same operation being understood (but vice versa) in the case of Perform signal combiner functions. Therefore, it is understood that under the operation of the divider, the device has a
    input port (through which the input signal is propagated) and at least four ports
    output (for each WlO of which an output signal is propagated), while in the
    In the case of functioning as a combiner, it has at least four input ports (for each of which an input signal is propagated) and an output port (through which the recombined output signal is propagated).
    In addition, in the present invention it is understood by divisor, combiner,
    20 divider / combiner or structure, to the device of the invention configured to separate and recombine electromagnetic signals that propagate at least two orthogonally polarized modes, on a single level (N = 1); It is not necessary to chain similar structures. Therefore, the device of the invention is the basic operating unit.
    The divisor / combiner of the invention is described below, in accordance with the
    scheme thereof of figures 1, 2 and 3.
    The device comprises two metallic and substantially parallel plates 101, 102
    30 to each other, where at least one of said two plates 101, 102 has a cavity 103 with a side wall 403 along its contour, and such that the two plates 101, 102 are
    they join by means of subjugation elements, such as tominos, closing the space formed between both plates 101, 102 by the at least one cavity 103. In a possible embodiment, and as shown in figures 1 and 2, only one of the two plates 101 have a cavity 103, the surface of the remaining plate 102 being in contact with the plate 101 with a cavity, substantially flat In Figures 1-2 and 6 the two plates 101, 102 are shown separately and without contact , in order to visualize the inside of the cavity 103; however, and as explained above, during operation of the device both plates 101, 102 are perfectly sealed.
    The device further comprises at least five openings 201, 202, located in at least one of the two plates 101, 102 and confined in the space confined by the at least one cavity 103. One skilled in the art will understand that there are so many openings 201, 202 as input and output ports present the device. In a possible embodiment, and as shown in Figures 1 and 2, the device has 1 + 4 putouts, one of the openings 201 being located in the plate 101 having a cavity 103, preferably in the center of symmetry of the cavity 103, and the four remaining openings 202 in the plate 102 without cavity 103. In another possible embodiment, as shown in Figure 6, all openings 201., 202 are located in one of the two plates, namely, in the plate which It has no cavity 103. That is, the relative position between the input and output waveguides can be in opposite directions or in the same direction, without this significantly affecting the electromagnetic operation.
    Each of the openings 201, 202 allows a waveguide to be connected to the device. Said waveguides are capable of propagating electromagnetic energy with at least two orthogonally polarized modes. In order to support two polarizations, and as mentioned above, the structure of each waveguide must be symmetrical, such as: circular, square or rectangular. In any case, the waveguides used are outside the scope of the present invention.
    Preferably, the connection of each waveguide in an opening 201, 202 should be
    such that the electromagnetic signal penetrates or exits the device so
    substantially perpendicular with respect to the plates 101, 102, or what is the same, substantially perpendicular with respect to the plane containing each opening 201, 202. Therefore, all the electromagnetic signals of input and output of the device
    (in figures 1-2 and 6: 1 input and 4 output in the case of functioning as a divider)
    they are substantially parallel to each other, their spindles being substantially
    perpendicular to plates 101, 102.
    The device further comprises in the space enclosed by the at least one cavity
    103, and anchored to one of the two plates 101, 102, as many metal adapter sections 301, 302 as openings 201, 202 are attached to the device.
    Each adapter section 301, 302 faces an opening 201, 202, such that each adapter section 301, 302 and its opposite opening 201, 202 are located in
    101, 102 different plates, and such that preferably the axis of symmetry of each section
    adapter 301, 302 matches the axis of electromagnetic propagation in a
    possible embodiment, and as shown in the figures, the device has five
    openings 201, 202, and therefore five adapter sections 301, 302.
    One skilled in the art will understand that the fan of adapter sections 301, 302
    it must be such that it allows obtaining a bu <. 'Or coupling it to the output of the device. For it,
    each perpendicular cut made to said adapter sections 301, 302 with respect to its rough axis J is variable. preferably being greater at the end in contact with the ploco than at the end closest to the opening.
    In a possible embodiment, each adapter section has a stepped shape, that is, the surface of each perpendicular cut made to said adapter section with
    with respect to its axia axis, it has its maximum and its minimum at both ends, being maximum at the end that is in contact with the plate, and it is gradually reduced as it approaches the opening with which it is located
    faced. In Figures 1-3 and 6, Adaptive Sections 301, 302 composed of cylinders of different mdios are shown (smaller the closer it is to the opening). Figure 4 shows adapter sections 301 composed of parallelograms of different overlapping sizes (smaller the closer it is to the opening).
    In another possible embodiment, each adapter section does not have a stepped shape, but the surface of each perpendicular cut made to said adapter section with respect to its axial axis has its maximum and minimum at both ends, being maximum at the end that It is in contact with the plate, and it is gradually reduced as it approaches the opening it faces. Figure 4 shows possible shapes, such as: cones or pyramids.
    The operation of the device, thanks to these adapter sections 301, 302, is based on the Turnsti / .e junction technique known in the state of the art, with the proviso that in the state of the existing technique only eS can be propagated One way only. To achieve this double polarization in the device of the invention, the confinement of the adapter sections 301, 302 inside the space formed by the at least one cavity 103 is key.
    The adapter sections 301, 302 divide or recombine the electromagnetic input and output signals selectively with the mode. For example, in the specific case of the device of Figures 1 and 2 operating as a splitter, with an input port and four output ports, the bimodal electromagnetic input signal enters the device through the waveguide connected to the corresponding opening 201. Once inside, the axially centered adapter section 302 with respect to said opening 201 divides the bi-modal electromagnetic input signal into four bi-modal electromagnetic output signals, propagating them to the remaining axially centered adapter sections 301 "with respect to the outlet openings 202 Each of said four adapter sections 301,
    it means that a predetermined electromagnetic signal existing within the space formed by] at least one cavity 103, can be routed to the corresponding output. In the output openings 202, the corresponding waveguides are located, through which the four bi-modal electromagnetic signals come out.
    In addition, to achieve a symmetric fimamiento of the device, the shape of the
    minus a cavity 103, the size and size of the adapter sections 301, 302 Yde
    the openings 201, 202, and the arrangement of said adapter sections 301, 302 and openings 201, 202 with respect to the axes of symmetry of the at least one cavity 103,
    They must be symmetric and equal. A structure of
    cavity 103 substantially square., although other forms of cavity 103 are
    possible, as shown in Figure 5. In addition, Figures 1-3 and 6 show
    adapter sections 301, 302 equal t :: n shape and size, composed of cylinders of different radii (smaller the closer it is to the opening), although other possible shapes are shown in Figure 4, such as: cones, pyramids and parallelograms of different overlapping sizes (smaller the closer
    find from the opening). All these adapter sections 301, 302 are disposed of
    symmetrical shape with respect to the center of symmetry of the cavity 103. Lastly, figures 1-3 and 6 show circular openings equal in size, such that the inlet opening in the case of operating the device as a divider (or opening output in the case of working as a combiner) is located in the center of symmetry of the cavity
    103, and the output openings (or input if the device works as a combiner)
    they are arranged symmetrically with resp .. "Cto to the center of symmetry of the cavity 103.
    Therefore, and to achieve symmetrical operation of the device, preferably the shape of the at least one cavity 103, the shape and size of the
    adapter sections 301, 302 and of the openings 201, 202, and the arrangement of said adapter sections 301, 302 and openings 201, 202 with respect to the symmetry shafts
    of the at least one cavity 103 are symmetrical and equal. In this case, a person skilled in the art will understand that if the divisor (or combiner) has 1 input port (or
    output) and n output ports (or input), electromagnetic output signals (or
    input) are equal, their magnitude being the product of the division between the value of the
    input signal (or output) and the number n of output ports (or input).
    However, in another possible embodiment, the shape of the at least one cavity 103 and / or the
    5 shape and size of the adapter sections 301, 302 and of the openings 201, 202, and / or the arrangement of said adapter sections 301, 302 and openings 201, 202 with respect to the axes of symmetry of the at least o cavity 103 They are asymmetrical and / or not equal. This asymmetric operation of the device, which gives rise to n output signals (splitter) or input (combiner) of different magnitude, can be interesting
    10 for different applications, such as: 00 divider where ooa of the outputs is intended to be a reference signal.
    That is, depending on the application, the level of division from the input port to every 000 of the output ports could be diverted from theorists ~ 6.02 dB 1 5 or by simple manipulation of the inherent symmetry of the present invention.
    Preferably, the device comprises Wl. set of posts 303, configured to act as resonance suppressors, thus avoiding unwanted resonances that can degrade the behavior of the device. In a possible embodiment said
    20 posts 303 are metallic. In another possible embodiment said posts 303 are dielectric.
    To achieve symmetrical operation of the device, said posts 303 must be the same in phonoa and size, for example with a square or circular section, in addition to
    25 possessing a symmetrical situation with respect to the symmetry axes of the at least one cavity 103. If, on the contrary, an asymmetric operation of the device were interesting, it is sufficient to alter some of the conditions described.
    Each post 303 is located in the space enclosed by the at least oo cavity 103, of such a sound that each of its two ends is in contact with oo plate 101,
    102 different. In a possible embodiment, said post is ooa only piece. In another possible embodiment, said post is composed of two pieces, such that each ooa of
    they join a different plate 101, 102.
    In or possible embodiment, and as shown in the figures, the device comprises
    5 four metal posts 303 ooa single piece, equal in shape and size and with square section; and o square cavity 103, such that each post is positioned with respect to its two adjacent posts and with respect to the two closest sides of the cavity 103, or at a distance of approximately 1/3 of the length of the side of the cavity 103 , thus obtaining 00 symmetrical operation of the divider / combiner.
    Preferably, the device further comprises a set of adaptation elements 304, preferably metallic, for example with a cross-sectional or rectangular section, configured to improve the adaptability and isolation of the present invention. To achieve 00 symmetric operation of the device, said
    15 adaptation elements 304 must be the same in shape and size, in addition to having a symmetrical situation with respect to the symmetry axes of the at least one cavity
    103. If, on the contrary, it is inh: restraining 00 asymmetric operation of the device, it is sufficient to alter some of the conditions described.
    Each adaptation element 304 is located in the space enclosed by the at least oo cavity 103, and in particular in the wall] atera1403 of said at least oo cavity 103, preferably with symmetry in plane ·· H, and in such a way that each 000 of its two ends is in contact with a different plate 101, 102.
    In the possible embodiment, and as shown in the figures, the device comprises four adaptation elements 304, equal in shape and size; and a square cavity 103, where each adaptation element 304 is located in the side wall 403 in the middle of each of the four sides of the square cavity 103, thus achieving 00 symmetrical operation of the divider / combiner.
    In addition, in alternative embodiments, additional discontinuities, such as
    irises, they can be introduced into the at least one cavity 103 to further improve the overall operation of the divider / combiner.
    The present device pennite the division / combination of electromagnetic signals
    5 bi-modal, comprising at least five ports, preferably 1 input port and 4 output ports (or vice versa), and preserving high performance and a very compact size (approximately 3A. Compared to 12A. Of state devices of the technique). This compact size facilitates manufacturing and operation in N levels of reduced size. For example, in the preferred case of having a
    10 bi-modal splitter with 1 input port and 4 output ports, it is possible, through the chaining of dividers of these characteristics (basic unit), to obtain a final power splitter with 4N outputs. Figure 7 shows an example of this type of embodiment for N = 2, that is, for 16 output ports. The latter feature is particularly advantageous for beam forming networks in systems of
    1 5 antenna feed. In addition, a smaller size implies a lower weight, and therefore a lower cost.
    The divider / combiner of the invention has good electromagnetic characteristics and easy manufacturing. For example, the two plates can be
    20 easily made from two metal blocks, using classical numerical control milling techniques, although alternative machining methods can be used. In principle, the component could be manufactured by melting the aluminum, or even from metallized plastic.
    2 5 Finally, the bandwidth obtained with the divider / combiner of the invention is significantly greater (double or triple) than that obtained with devices existing in the state of the art.
