MULTIPURPOSE AIRCRAFT ANTENNA FEEDER SYSTEM Russian patent published in 2015 - IPC H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: multi-purpose aircraft antenna feeder system contains the antenna part, the switching and separating device, the control unit, the antenna part contains front UHF antenna, the right and left horizontal polarization antennas of ranges L, S, the vertical polarization antenna of ranges L, S, the back horizontal polarization antenna of ranges UHF, L, S and the vertical polarization antenna of ranges L, S, the switching and separating device, the control unit, five switchboards for two ways, five frequency and dividing devices, the operated phase shifter, the input control unit is connected to UHF, L, S radio equipment, the vertical gyro reference, identifier of course angle of radio beacon, and outputs - to the switching and separating device, switchboards and the phase shifter, the first switchboard is connected from one side to the switching and separating device, and from another side - to antennas directly or through frequency distributing devices, and from back horizontal polarization antenna - through the phase shifter.

EFFECT: stable operation of UHF radio equipment during circular scanning of space in the azimuthal plane, including in interference zones and in L, S frequency ranges with considerable roll of the aircraft.
