    opposite edges and are connected by conductive bridges, with the first and second contact groups of the second and third CDs being rotated by 90 ° relative to the corresponding contact groups of the first CD. The third contact groups of the second and third CD are connected respectively with the third and fourth contact groups of the first CD. All P 7 form a rectangular matrix, the number of columns of which corresponds to the number of inputs of the device, and the number P 7 in a column - the number of outputs of the device. In Antenna Switching, the Invention refers to radio engineering and can be used to connect multiple transmitters with multiple antennas.
    The aim of the invention is to reduce the size with an increase in the number of switched feeder lines and expanding switching capabilities.
    FIG. 1 shows an antenna switch in the form of a 3x4 matrix; in fig. 2 and 3
    - accordingly the circuit and the design of the switch; in fig. 4 - antenna switch circuit in the form of a 3x4 matrix; in fig. five
    -antenna switch in the form of a 4x8 matrix; in fig. 6 - antenna switch in the form of a 4x8 matrix with additional columns of switches and an increased number of switches in each column.
    The antenna switch contains the first feeder lines 1 located in the first plane 2 and being inputs of the antenna switch, the second feeder lines 3 located perpendicular to the first feeder line 1 in the second plane 4 parallel to the first plane 2 and being the outputs of the antenna switch, and the third figs. 5 core lines, which are parallel to the second feeder line m 3, are located in the third plane 6, parallel to the first 2 and second 4 planes, and are additional outputs of the antenna switch, the reference in the opposite direction from its exits. The first 1, second 3 and third 5 feeder lines are made in the form of symmetric transmission lines. The first plane 2 may be located between the second 4 and third 6 planes. In each crossing of the first 1, second 3 and third 5 feeder lines, a switch 7 is installed, on the axis
    Additional columns can be entered for the reader with an increased number of P 7 in the column. The antenna switch reduces the size with an increase in the number of switched channels due to the introduction of the third PL and the introduction of the third KD into each P 7 and makes it possible to connect each FL 1 to the required PL 3 or 5. Introducing additional columns P 7 allows you to bypass the faulty and previously involved P 7, which improves the switching capabilities of the device. 3 hp f-ly, 6 ill.
    8 of which, perpendicular to the first 1, second 3 and third 5 feeder lines, in the first 2, second 4 and third 6 planes, the first 9, second 10 and third 11 contact disks are fixed, respectively.
    The first contact disk 9 has four contact groups 12-15, and the second 10 and third 11 contact disks are identical to each other and have respectively three contact groups 16-18 and 19-21. The first and second contact groups 12 and 13, 16 and 17, 19 and 20 of each contact disk 9-11 are located on their diametrically opposite edges, the third contact group 14,
    18 and 21 is located at an angle of 90 ° to them, and the first and second contact groups 16 and 17, 19 and 20 of the second 10 and third 11 contact discs are rotated relative to the first and second contact groups 12 and 13
    The first contact disk 9 on the corner of the 90th. The fourth contact group 15 of the first contact disk 9 is diametrically opposed to its third contact group 14.
    The contacts of the first contact group 12, 16 and 19 of each contact disk 9-11 are connected by conductive jumpers 22-24 with the corresponding contacts of the second contact group 13,17 and 20, the contacts
    the third contact group 14 of the first contact disk 9 is connected by conductive bridges 25 with the corresponding contacts of the third contact group 18 of the second contact disk 10, and the contacts
    the fourth contact group 15 is connected by conductive bridges 26 with the corresponding contacts of the third contact group 21 of the third contact disk 11.
    Each switch 7 can be placed in a rectangular frame 27, on
    using ceramic holders 28, fixed contacts 29 are fixed, connected to the contacts of corresponding contact disks 9-11, to which they can be fixed by means of ceramic holders 30. Current-conducting jumpers 22-26 can be made, for example, of copper tubes. All switches 7 form a rectangular matrix, the number of columns 31 of which corresponds to the number of inputs of the antenna switch, and the number of switches 7 in each column 31 - the number of outputs of the antenna switch.
    The antenna switch matrix may contain at least one additional column 32 from both its outputs and its additional outputs, and at least one switch 7 can be entered into each of columns 31 and additional columns 32 from antenna switch inputs.
    Antenna switch works as follows.
    When transmitting signals to the first feeder lines 1 of transmitters, these signals can be rotated by the axes of the 8 switches 7 and fed to the required feeder lines from among the second 3 and third 5 feeder lines to connect them to the corresponding antennas (not shown). For example, signals from the first feeder links 1 (Fig. 4) are respectively fed to the second output of the antenna switch from among the second feeder links 2, located in the second plane 4, to the second auxiliary output from among the third feeder links 5 ,. located in the third plane 6, and the third output from among the second feeder lines 2. Thus, the antenna switch allows each input of the antenna switch to be connected to any of its outputs or additional outputs. Introducing the third feeder lines 5 with their specified orientation relative to the first 1 and second 3 feeder lines and the third contact disk 11 with the indicated connection of its contact groups 19-21 allows to reduce the dimensions of the antenna switch with a twofold increase in the number of switched channels in comparison with the known switch. An antenna switch in the form of a 4x8 matrix (Fig. 5), consisting of four columns of 31 switches 7, allows 16 channels to be switched, and the same 4x8 matrix of the known is only eight channels.
    In the maintenance of additional columns of switches 7 on the side of the outputs and additional outputs of the antenna switch, and increasing the number of switches 7 in each column 31 and additional column 32 expand
