    The invention relates to antenna technology, in particular to phased antenna arrays (PAIR) with electric beam scanning
    Equidistant PAAs with an open beam scanning sector are known, in which the diameters of the controlled radiator of the array are realized, close to rectangular, so that the interference maxima outside the specified scanning sector are effectively suppressed. The directional pattern of the controlled emitter is close to rectangular, achieved by introducing communication circuits of the emitter grating with neighboring emitters, while the aperture in the array is effectively excited when one controlled emitter is excited by a single emitting element TI 3-
    In the specified device, communication elements are included between the radiators. When one controlled input is excited in the lattice, three emitters are excited, and the amplitude-phase distributions when two neighboring controlled inputs are excited are, as it were, overlapped. The possibility of forming a diagram of a controlled emitter close to a rectangular in the specified device is limited due to the small number of excited emitters when powered from one controlled input.
    The closest to the present invention is an antenna array, which contains modules located along a certain spatial line, each of which consists of two groups of emitters and an excitation unit. The excitation unit, in turn, contains an input, a power distributor for two channels, the outputs of which are connected by transmission lines to each of the groups of emitters of the corresponding module. These transmission lines include communication elements with groups of emitters of other modules.
    The communication elements are made in the form of two segments of transmission lines with directional couplers, so that when the input of one module is excited, groups of emitters of other modules are excited in series. The size of the effectively excited aperture when excited
    d of each of the modules is commensurate with the entire aperture of the lattice. The amplitude-phase distribution approximates well the sinX / X type function, which makes it possible to realize the directivity pattern of the controlled element that is very close to rectangular 2.
    However, such a device is due to the serial characteristics of the connections between the groups of emitters in a narrow band.
    The purpose of the invention is to expand the working frequency band by limiting the number of modules with which each corresponding module is connected.
    This goal is achieved by the fact that in an antenna array with a limited scanning sector made of modules located along a certain spatial line, each of which consists of two groups of emitters and an excitation unit containing the input, the power distributor for two channels, the outputs of which are connected transfer to each of the groups of emitters of the corresponding module and the communication elements included in the transmission line with the group of emitters of emitters of other modules, the communication elements are made in the form of two groups per sequential taps connected sequentially to each transmission line modules, with the first group of directional taps having a first output for connecting via a transmission line to the second input of a non-neighboring group of directional taps related to the radiators of the non-neighboring module, and the second output for connection via a transmission line with the first input of a neighboring directional group. taps belonging to the radiators of the adjacent module, and the second group of directional taps have at least the first input for connecting via a transmission line to the second output of the neighboring group of directional taps, relating to the radiators of the neighboring module, and the second input for connecting - via a transmission line with the first output of a non-adjacent group of directional couplers belonging to the radiators of the non-neighboring module.
    In addition, the total number of directional couplers of each of the two groups included in the transmission lines of the module is equal to the number of modules excited when the input power of the corresponding module is energized.
    When executing a block of excitation of one or a group of modules on. single-layer printed circuit board at the intersection of the strip transmission lines included three-way directions. full couplings with; intersecting strip lines are connected to the diagonal arms of said coupler c. full bond.
    The entrances or entrances of the direction tilters of the Modules, located near the edge of the antenna array, are connected to the agreed load.
    FIG. 1 shows the electrical circuit of the proposed antenna solution to FIG. 2 - dvuhshleyfovy directional coupler in microstrip, in plan; in fig. 3 is the same section; in fig. 4 - three-stringed microstrip directional coupler; in fig. 5 shows a microstrip communication device.
    The device diagram (Fig. 1) consists of 8 modules (1 ... 1g). Each of the modules consists of two beams (... 2g, 2g) (or two groups of bodies in the case of two-dimensional wobble emitters) and an excitation unit that includes an input (3 ... 3g) and a two-channel power distributor (4. ..40), transmission lines (5.5; .. 50 ,, connecting the outputs of the power distributor to two channels (4.4jJ.. 4c {4d) and groups of radiators (2.2:, ..28, 2d). In each of the Transmission lines (5.5 ... 5d, 5d), communication elements are included in the form of two groups of directional couplers (b ... 6d) and (7 ... 7g). These groups are highlighted by a dotted line in module 1. The first group of directional couplers (b ... 6d) has extremely th
    0 as one 8, which is connected with the help of transmission line 9 with the second input of 10 non-adjacent groups of directional couplers belonging to radiators (2.2 ... 2g, 2g) of the non-neighboring module (1 ... 1e).
    5 There is also a second output 11 connected by a transmission line to the first input 12 of the second group of directional couplers belonging to the radiators of the adjacent module. The second group of directional couplers (7 ... 7 d) has at least the first input 12 connected by a transmission line to the second output 11 of the neighboring group of directional otvety 5 related to the radiators of the neighboring module, and the second input 10 connected by a transmission line with the first output of an unbounded group of directional taps, related to the radiators of the non-neighboring module (Fig. 1, the indicated connections are shown in modules 1, 12 and 13)
    The antenna array operates as follows.
    five
    When excited, for example, module 1 from the 34SPC input, power is supplied to the power distributor on two channels 4 4 and on two transmission lines 54 and. Through the first group of directional couplers 6 microwave
    0
    ; power is fed to the inputs of the directional couplers of the second group both in adjacent modules x 1z and 15, and in non-neighboring 12 and 1 g. Thus, upon excitation of modulus 1 (from microwave input 3, power excites groups of radiating elements both in the module being excited and in the modules of Fig. 1 by vectors conditionally showing the amplitude-phase distribution on the lattice aperture. Selecting the coupling value of the directional couplers in each of the groups, it is possible to realize a diagram of a controllable element (mod 5 L) in the lattice approximating sufficiently well, which is required. When excluding the inputs of the module, groups of radiating elements in two adjacent modules are excited.
    0 the number of directional couplers in each of the groups can accordingly increase the number of adjacent excited modules. The proposed device by selecting the number of bw zan-. 5 modules with each other allows one to gain an advantage over the prototype device, namely, to expand the operating frequency band in which the required radiation pattern of the controlled element is realized.
    An important feature of the proposed device in comparison with the prototype is the possibility of an independent choice of the magnitude of the connection between the modules, which provides ample opportunities for synthesizing the required radiation pattern of the controlled element in the lattice. A large number of directional openers and a large number of transmission lines connecting inputs and outputs of various directional couplers, make it preferable to perform the device using the technology of belt-shaped stripline systems.
    FIG. 2 and. 3 shows a known device — a two-loop microdisciplinary directional coupler used in the invention. A two-loop directional coupler 13 is provided on the dielectric plate. On one side of the board 14 there is a wire screen 15, and on the other is a printed circuit 16. The printed circuit contains microstrip lines 17 and 18 of the transmission, connected by loops 19 and 20.
    The magnitude of the connection between the lines 17 and 18 is determined by the thickness C of the loops 19 and 20. If microwave power is supplied to the channel P, the channel P will be uncoupled. The power of the channels P and P is divided in relation to the ratio of the wave conductivities of the loops 19 and 20 and the wave conductivities of the transmission lines 17 and 18.
    FIG. 4 shows a three-loop coupled directional coupler 21 implementing a zero decibel coupling. The parameters of loops 22, 23, and 24 are chosen so that when power is supplied from the input P of the 2.5 transmission line, all the power minus the ohmic sweat falls into the shoulder of the relay protection line 26 of the transmission. By virtue of the symmetry of the coupler when power is supplied to the shoulder P. Line 25, the power falls into the shoulder P of line 26.
    These three-lane directional coupler 21 with a link of zero decibels or full link is used at the intersection of two / transmission lines. Moreover, the intersecting transmission lines are connected by 0 to the diagonal arms of a three-loop coupler with full coupling.
    FIG. 4 and 5, the dimensions of A and B are close to a quarter of the wavelength in the dielectric. FIG. 5 shows a diagram of the extraction of the communication elements of a module in microstrip design using the devices shown in FIG. 2 and 4. The circuit contains an input 3. Power distributor
    0 to two channels 4. The first groups of directional couplers 6 are the first output 8 and the second output 11. There is a second - a group of directional taps 7. the first 12 and the second 10 inputs. The second outputs 11 of the first communication elements 64 are connected by transmission lines 9, for example, coaxial, to the first inputs of 12 second groups of directional responses of adjacent modules Ij and 1. The connection of non-neighboring modules includes transmission lines 27 and three-directional directional couplers 21 included in the intersection of the transmission lines 5 and 3, the module
    - and transmission lines 27.
    The outputs and inputs of the directional peripherals of the Field Modules are connected to matched loads 28 (Fig. 2).
    0 The proposed technical solution in comparison with the prototype device allows to realize greater broadband. In addition, the proposed device provides
    5, it is possible to independently choose the magnitude of the connection between the radiating elements (groups of elements) of modules in the lattice, which makes it possible to more flexibly solve the problem of synthesizing the required diagram of the controlled element E of the PAR.
