[0004] OBJECT OF THE INVENTION
[0005]
[0006] The present invention relates to a signal phase shifter, more particularly, it refers to a mechanical type phase shifter for feeding an antenna.
[0007]
[0008] The signal phase shifter of the invention makes it possible to produce a gap between the input signals to the system mechanically. In addition, it allows controlling the magnitude of the offset produced in each of the signals. In this way, the reconfiguration of a radiation pattern of a given set of radiant slots is allowed.
[0009]
[0010] BACKGROUND OF THE INVENTION
[0011]
[0012] Today, there is a wide variety of signal distribution methods for feeding antenna clusters. These methods make use of both traditional electromagnetic guidance systems, as well as newer systems, based on pin beds. Usually, this distribution is done so that the input signal is guided to all the antennas with the same phase.
[0013]
[0014] Sometimes, however, it is necessary to feed the antennas with different phases. The radiation pattern transmitted by the antenna can be controlled thanks to the variation in the relative phase of the transmitted signal. The control of the radiation diagram makes it possible to electronically orient a transmission beam without any movement of the antenna.
[0015]
[0016] Therefore, in the feeding of antennas, it is interesting to generate a radiation pattern determined at each moment, and, therefore, a lag in the determined signal.
[0017]
[0018] There are different methods to produce the desired offset in a signal. The simplest is the use of connection cables of different lengths in order to connect each antenna element with a common power point. However, in this way the offset between the signals is fixed, so it is not possible to modify the offset between the signals depending on the direction to which the transmission beam is to be transmitted.
[0019] Another method that can be used to achieve a radiation pattern determined by the signal offset consists in the use of electronic phase components. However, the use of this class of components is very expensive and may not be appropriate for all applications as they introduce losses to the system.
[0020]
[0021] Finally, a method that has been used to produce a lag in a signal, is the use of waveguides that define circular and concentric paths, which allow to cause a progressive lag in the signal, which obeys a specific formula because it depends on the Different distance traveled along the guide. However, this solution also sets a certain offset in the signal that cannot be modified later.
[0022]
[0023] DESCRIPTION OF THE INVENTION
[0024]
[0025] The invention relates to a system capable of controlling the offset produced to each of the signals of a set of signals by mechanical movements, comprising:
[0026] - a phase shifter module, comprising:
[0027]
[0028] or a first circular sector, with a first center located on one side of the phase shifter module and covering a first angle, and
[0029]
[0030] or a second circular sector, with a second center located on the side opposite to the first center, and covering a second angle, rigidly attached to the first circular sector;
[0031] where the first and the second circular sector comprise a first pin bed located on a flat surface, the first pin bed being configured to include a first set of waveguides selected from the slot types with recess (GGW) and crest with hollow (RGW);
[0032] - a mobile rotation axis, adapted to be coupled to the phase shifter module; - a fixed external support;
[0033] - a first cover located on the phase shifter module, at a certain distance above the height of the first pin bed, attached to the external support, and comprising a first set of grooves, located on the waveguides of the first set of guides cool;
[0034] - a first set of metal planes, which act as short circuits, adapted to be introduced inside the waveguides of the first set of waveguides, the first set of metal planes being rigidly attached to the first cover, at a certain distance from the first set of slots;
[0035] - an output module, comprising a second pin bed attached to the top of the first cover and configured to include a second set of waveguides selected from the GGW and RGW types, located next to the first set of slots ;
[0036] - a second cover located on the second pin bed, and attached to the external support.
[0037]
[0038] The inclusion of a rotation axis connected to the phase shifter module allows its rotation, without the rest of the system moving, so that the distance between the signal input to the phase shifter module is modified, and the metal plane that It acts as a short circuit. In this way, the offset between the signals that enter the phase shifter module can be modified, because by turning the phase shifter module completely the distance traveled by the signals is modified differently in each one, because for the same angle variation in two Waveguides that define concentric circular paths, but with a different radius, the distance traveled varies differently depending on the radius. Thus, by varying the angle traveled by all the signals, the phase of these signals is modified differently from each other and the gap between them is varied.
[0039]
[0040] The use of gap-type guides, allows the relative movement of the modules with respect to the covers, without causing leakage of the electric field, because the confinement of energy occurs through the application of high impedance conditions, making use of the beds of pins.
[0041]
[0042] Alternatively, the waveguides of the first set of waveguides of the phase shifter module may be equally spaced, to produce a linear progressive offset.
[0043]
[0044] The application of a progressive lag is necessary in certain applications, so the system's ability to adopt such a lag allows greater versatility in the applications in which the system can be used.
[0045]
[0046] Preferably, the metal planes of the first set of metal planes may include two recesses in their lower zone.
[0047] This form makes it possible to prevent the electric field from passing through the margins that are left between the metal plane and the pins that surround the waveguides in order to allow relative movement.
[0048]
[0049] In an alternative embodiment, the second angle, of the second circular sector, can be null, such that the phase shifter module is in the form of a circular sector that encompasses only the first angle.
[0050]
[0051] In this way, the construction of the phase shifter module is simplified, still allowing to control the offset by the relative movement of the phase shifter module with respect to the metal planes.
[0052]
[0053] The first angle can also be equal to the second angle, thus producing a null offset.
[0054]
[0055] In this way, it is possible to separate the output of the splitter module from the input to the output module avoiding the power coupling that can be produced, without the need to apply a lag in the output signals.
[0056]
[0057] In the described signal system, the second cover can comprise a set of radiant slots, allowing to feed an antenna.
[0058]
[0059] In this way, the signal shifting system can be used to feed an antenna, in particular, to direct the beams radiated by the radiating slots, originated by the signals entering the phase shifter module, by controlling the gap between these signals. The electronic orientation of the signal simplifies the process of feeding the antenna. In addition, the generation of the offset by the system of the invention, allows to obtain a high reliability in the feeding of the antenna, since it can be applied to any number of guides, with a good bandwidth, and to reduce the costs.
[0060]
[0061] Preferably, the phase shifting system of the invention may further comprise:
[0062] - a splitter module, to divide an input signal into several output signals, comprising a third pin bed located on a flat surface, the third pin bed being configured to include a third set of waveguides selected from among the GGW and RGW types, where the splitter module it is connected to the phase shifter module and the first and third covers can be rigidly connected; Y
[0063] - a third cover located on the divider module, some distance above the height of the third pin bed, and attached to the external support.
[0064]
[0065] The inclusion of a divider module in the offset system allows the phase shifter module to be used to produce the offset of a single signal, divided into several equal signals. In this way, the system can carry out the control of the radiation diagram, and therefore the addressing of the beams of that single signal, to ensure the correct supply of the antenna with that signal.
[0066]
[0067] In one embodiment, the waveguides of the splitter module may be configured in the form of a tree. This configuration allows to obtain the maximum bandwidth in the transmission of the signals through the waveguides.
[0068]
[0069] Alternatively, the waveguides of the splitter module can be configured in series. This configuration simplifies the manufacturing process of the splitter module, and also allows the input to be maintained at a fixed point, avoiding the need to use a connection that allows the movement of the input points. Thus, the input to the splitter module simply rotates, without scrolling, facilitating the input connection.
[0070]
[0071] Preferably, the first and third set of waveguides are of the GGW type and the second set of waveguides is of the RGW type, and where the output module further comprises a set of coaxial pins, located in the vicinity of the slots. of the first set of slots, to transform the horizontal electric field generated in the waveguides of the GGW type into a vertical electric field adapted for the waveguides of the RGW type.
[0072]
[0073] The use of RGW waveguides, in the output module, makes it possible to simplify the control of the radiation emitted by the slots to allow the addressing of the signal beams. In addition, the inclusion of a coaxial pin allows the lower signal of type GGW to be coupled with the upper signal of type RGW.
[0074]
[0075] Preferably, the output module may further comprise a set of transition zones, located between the slots of the first set of slots and the RGW type waveguides of the second set of waveguides, where the transition zones can have a configuration similar to the waveguide type RGW, but with an anterior zone with a lower height than that of the guide, and a posterior zone with a height less than the height of the previous zone.
[0076]
[0077] The inclusion of a transition zone prior to the RGW waveguide allows the correct adaptation of the signal from the coaxial pin to the waveguide. The shape of the adaptation zone is the one that allows a better adaptation.
[0078]
[0079] Preferably, the system may comprise a motor, coupled to the axis of rotation and configured to produce rotation of the axis of rotation.
[0080]
[0081] The engine allows the rotation of the system, and therefore the control of the offset produced automatically.
[0082]
[0083] Alternatively, the arrangement of the elements of the phase shifting system can be modified, so that the phase shifter module is located on the third cover of the splitter module, and where the third cover also comprises a second set of slots and a second set of planes metallic, acting as short circuits, rigidly attached to both sides of the third cover, the metal planes being adapted to be introduced inside the waveguides of the first and third waveguide sets, at a certain distance from the second set grooves, so that the signal passes through the grooves, where the axis of rotation is rigidly attached to the third cover, so that the divider module and the phase shifter module remain fixed.
[0084]
[0085] The placement of the divider and phase shifter modules on two levels allows the input to the divider module to be maintained in a fixed position, so that the input connection to said module is greatly simplified. In addition, in this embodiment, the only element coupled to the mobile rotation axis, is the third cover, of the splitter module, making the power necessary to modify the offset in the signal to be less, having to produce less rotation. elements.
[0086]
[0087] Preferably, the third set of waveguides is configured in series and the slots of the second set of slots are rotated an angle ( y ) with respect to the direction of the waveguides of the third set of waveguides.
[0088] In a series embodiment, which is easier to manufacture, the use of rotated grooves, allows the correct adaptation of the lower, rectilinear guides, to the upper, curvilinear guides, avoiding the sealing of the groove when rotating the mechanism.

[0115] PREFERRED EMBODIMENT OF THE INVENTION
[0116]
[0117] Figure 1 shows a preferred embodiment of the mechanical phase shifter system (1), where the system (1) comprises a phase shifter module (2), which in this case is broadband by means of retarding filters (True Time Delay, TTD), with a first cover (14), an output module (17), with a second cover (20), a divider module (5), with a third cover (22), a rotation axis (12) and a motor.
[0118]
[0119] Figure 2 shows a detail of the splitter module (5), which in turn comprises a pin bed (8) located on a flat surface, in which waveguides (9) of the GGW type are located, where The pin bed (8) allows the application of high impedance conditions. On the other hand, the guides (9) that are on the pin bed (8) have a tree-shaped configuration, which provides a greater bandwidth, with an input and 8 outputs. In this way, the splitter module (5) allows the input of a signal through its single input, which forks through the waveguides (9) allowing 8 signals to be produced at the 8 outputs of the bed of pins (8).
[0120]
[0121] Figure 3 shows the splitter module (5) including a third cover (22) located above said module (5). Specifically, the cover (22) is located above the height of the pins of the pin bed (8), defining an air gap between the edge of the pins and the cover (22). Even so, an effective confinement of the energy in each of the guides (9) is achieved by applying high impedance conditions on the surrounding pins of the first pin bed (8). The application of these conditions allows to avoid electric field leaks in the distribution of the signals.
[0122]
[0123] Figure 4 shows a detail of the phase shifter module (2). The phase shifter module (2) is shaped like a circular sector (3), with an inner radius (Ri) and an outer radius (Re), and covers an angle (a). The phase shifter module (2) comprises a pin bed (10) located on a flat surface. In the pin bed (10) a set of waveguides (11) of GGW type are defined, which define inputs to the phase shifter module (2), all located in the foreground, and outputs, all located in the background. . Waveguides (11) define circular and concentric paths that are located at radii other than the circular sector (3), being concentric with said circular sector (3). Specifically, they are placed in an equally spaced manner, which allows the gap between them to be progressive. The space between the guides (11) is large enough to prevent a power coupling between the signals flowing through the different waveguides (11).
[0124]
[0125] By guiding the signal through waveguides (11) that define circular and concentric paths with different radii, there is an offset of each of the signals with respect to the others, which is due to the difference in distance That runs through each signal. In each of the waveguides (11) of the phase shifter module (2) the distance traveled corresponds to the formula:
[0126]
[0127] d = R i * a
[0128]
[0129] Where it corresponds to the radius of each of the waveguides (11), so that the larger said radius, the distance traveled will be greater.
[0130]
[0131] The splitter module (5) is rigidly connected to the phase shifter module (2), the splitter module (5) having as many outputs as inputs has the phase shifter module (2), in this case 8. The arrangement of the outputs of the splitter module (5) ) also coincides with the layout of the inputs of the phase shifter module (2), so that the signal that has been divided into the splitter module (5), exits through the outputs of the splitter module (5) and enters the module phase shifter (2), each of the signals traveling a different distance to the output of the phase shifter module (2), and thus obtaining 8 outdated output signals from an input signal.
[0132]
[0133] The phase shifter module (2) has a first cover (14), which, as in the case of the splitter module (5), is located above the height of the pin bed pins (10), defining between the edge of the pins and the cover (14) an air gap. In addition, an effective confinement of energy is also achieved through the application of high impedance conditions, thus avoiding leakage of the electric field in the distribution of the signals.
[0134]
[0135] Figure 5 shows the assembly of the phase shifter module (2), and the output module (17), where the first cover (14), located on the phase shifter module (2) further comprises grooves (15) located on each of the waveguides (11) of the phase shifter module (2), and metal planes (16) rigidly attached to said first cover (14), which are shaped circular. The metal planes (16) are located inside the waveguides (11) of the phase shifter module (2) at a distance equal to a quarter of the wavelength of the signal in the waveguide (11) of each of the slots (15).
[0136]
[0137] In this way, the metallic planes (16) act as short circuits, since they reflect the signal that passes through the waveguides (11) of the phase shifter module (2). The signal reflected in the short circuit (16) intersects the signal that travels through the waveguides (11) generating a maximum electric field at a distance equal to a quarter of the wavelength of the signal in the waveguide (11). At that point, there are the slots (15) of the first cover (14), which are excited to make the signal travel through them, moving from a lower level to a higher level.
[0138]
[0139] Figure 5 also shows the output module (17), which is placed on the first cover (14) and comprises a pin bed (18) configured to include waveguides (19) of the RGW type, which are placed in parallel , after each of the slots (15). Thus, the signal that rises through the excited slot (15) passes to the RGW guide (19). The signal that rises through the slot (15), however, is not adapted to be transmitted properly through the waveguide (19). Therefore, a coaxial pin (23) is placed in the vicinity of the slot.
[0140]
[0141] Figure 6 shows a detail of the metallic plane (16) that acts as a short circuit, which has two recesses in its lower zone. This particular form allows to avoid the propagation of the electromagnetic wave through the margins between the metallic plane (16) and the pins of the pin bed (10), necessary to allow the relative movement of these two elements.
[0142]
[0143] Figure 7 shows a detail of the groove (15) and the coaxial pin (23), whose function is to convert the horizontal electric field generated in the waveguide (11) of the GGW type of the phase shifter module into a vertical electric field adapted for the waveguide (19) of the RGW type of the output module (17). In addition, the output module (17) comprises a transition zone (24), which can also be seen in Figure 7, located between the slot (15) and the waveguide (19) type RGW. The transition zone comprises an anterior zone (25) with a shape similar to that of the waveguide (19), but with a lower height, and a posterior zone (26) having a configuration similar to the waveguide ( 19), but with a height less than the height of the previous area (25).
[0144] On the pin bed (18) of the output module (17) a second cover (20) is placed which is located above the height of the pins of the second pin bed (18).
[0145]
[0146] Placing the output module (17) in a plane above the plane containing the phase shifter module (2) and the divider module (5) through the proposed system allows relative movement between said output module (17) and the modules divider (5) and phase shifter (2).
[0147]
[0148] In order to cause this relative movement, the phase shifter module (2) is connected to a rotation axis (12). The axis of rotation (12) is moved by means of a motor, causing the whole assembly that make up the divider modules (5) and phase shifter (2) to move in solidarity. On the other hand, the first (14) and third (22) covers, in the proposed embodiment are rigidly joined and form a single piece, both of which are attached to an external support (13). Thus, the axis of rotation (12) produces a rotary movement of the divider module (5) and the phase shifter module (2), while the third (22) and first (14) caps, and their corresponding grooves (15) , the metal planes (16), the output module (17) and the second cover (20) remain fixed as they are attached to the external support (13). This varies the distance the signal travels from the input in the splitter module (5) to the metal plane (16) that serves as a short circuit and that sends the signal through the slot (15) of the first cover (14) to the output module (17). The variation of said distance implies a variation in the phase of the output signals. In this way, it is possible to control the magnitude of the lag that occurs between the signals. Thus, the effective distance traveled by a signal (d ’) through the phase shifter module (2) responds to the formula:
[0149]
[0150] d '= R * a'
[0151]
[0152] Where a ' is the defined angle between the plane comprising all the inputs to the phase shifter module (2) and the plane where the metal planes (16) are located.
[0153]
[0154] For example, when rotating the divider module (5) and the phase shifter module (2) in the counterclockwise direction, the distance that the signals must travel through the phase shifter module (2) is shorter, since they meet the metal plane (16) ) correspondent. As explained, the distance on each path decreases depending on the variation in the angle {a - a '), and consequently the magnitude of the gap between two of the paths also decreases as a function of the variation in the angle ( a - to').
[0155] In an alternative embodiment, the splitter module (5) may be configured in series. In this case, the signal enters through a side located on the axis of rotation, so that by rotating the phase shifter module (2), the input of the splitter module (5) does not shift, but rotates.
[0156]
[0157] Figure 8 shows an alternative embodiment of the phase shifter module (2), where the flat bottom surface comprises a first circular sector (3), whose center (4) is located on a first side of the phase shifter module (2) and encompasses a first angle (a) and then a second circular sector (6) whose center (7) is located on a second side of the phase shifter module (2), opposite the first side, and encompassing a second angle (P), allowing thus obtain positive offsets, if the first angle (a) is greater than the second angle (P), and negative, if the first angle (a) is less than the second angle (P).
[0158]
[0159] In a preferred embodiment, the first angle (a) may be the same as the second angle (P), so that the offset is zero. However, in this embodiment, the advantage is also obtained that since the outputs of the splitter module (5) are separated from the outputs of the phase shifter module (2), the power coupling that could occur between the splitter module (5) is reduced. and the grooves (15), of the first cover (14), excited.
[0160]
[0161] Figure 9 shows an alternative embodiment, where the divider module (5) and the phase shifter module (2) are located in different planes. The first (14) and the third cover (22) are not joined, but are in different planes. In addition, the third cover (22), like the first cover (14), also comprises a set of grooves (27) aligned with each of the waveguides (9) of the divider module (5). The third cover (22) also comprises a set of metal planes (28) rigidly connected to both sides of said third cover (22), and adapted to be introduced inside the waveguides (9, 11), both of the divider module (5) and of the phase shifter module (2).
[0162]
[0163] Thus, the dividing module (5) comprises an input that is divided by providing several signals, each of these signals encounters one of the metallic planes (28) that acts as a short circuit and reflects the received signal thus exciting one of the slots ( 27) of the third cover (22), which allows the signal to pass through it to the phase shifter module (2).
[0164] In this embodiment, the third cover (22) is rigidly attached to the axis of rotation (12), while the first cover (14), the phase shifter module (2), the divider module (5), the output module (17 ) and the second cover (20) are fixed. Thus, it is only necessary to move the third cover (22) with the short circuits (28), instead of moving the two phase shifter modules (2) and divider (5).
[0165]
[0166] Figure 10 shows the splitter module (5) with a series configuration, where the grooves (27) of the third cover (22) are preferably rotated an angle ( y ) with respect to the waveguide (9 ) of the divider module (5). In this way, it is possible to adapt the rectilinear waveguides (9) of the divider module (5) to the curvilinear waveguides (11) of the phase shifter module (2), so that, by moving the third cover (22), The slots (27) are capable of effectively connecting the waveguides (9) of the divider module (5) with the waveguides (11) of the phase shifter module (2).
[0167]
[0168] The system set (1) phase shifter can be used to power an antenna. To this end, the second cover (20) comprises a set of radiant grooves (21), as seen in Figure 11, which allows radiation of the signals to be emitted from inside the waveguide (19), outward, each with an appropriate offset. The variation of the phase in each guide (19) modifies the aiming of the radiation diagram, thus concentrating the field radiated in one direction or another.
[0169]
[0170] In order to provide adequate addressing of the emitted radiation and improve the efficiency of the antenna feeding process, the radiating slots (21) have a width smaller than the waveguides (19) on which they are placed, and are they have longitudinally alternatively closer to one edge of the waveguide (19) and closer to the other edge of the waveguide (19).
