AIRBORNE ANTENNA FEEDER SYSTEM Russian patent published in 2014 - IPC H01Q1/28 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and specifically to antenna equipment, designed to service on-board radio equipment for short-range navigation and landing aircraft in the ultra-high frequency range. The airborne antenna feeder system comprises transceiving antennae with corresponding beam patterns, connected to each other by a feeder system which includes amplifiers, radiofrequency feeders connected to the on-board radio equipment, wherein the transceiving antennae are mounted on the front and rear edges of the left-side and right-side wings of the aircraft and have weakly directional beam patterns that are mirror symmetric relative to the longitudinal plane of symmetry of the aircraft, wherein the antennae are designed to be mounted on an object such that the beam patterns of adjacent antennae in the horizontal plane overlap at a level which provides a stable radio link, wherein the output of each antenna is connected to the radio signal carrier frequency-independent input of the served radio equipment, in which there is a device for selecting and turning on a combination of operating antennae, which facilitates processing of radio signals received by the operating antennae and generation of a resultant received information signal, frequency division of transmission and reception signals, alternate turning on of one or two operating antennae during signal transmission.

EFFECT: providing stable operation of on-board equipment for short-range navigation and landing aircraft with circular scanning of space with horizontal polarisation of operating signal.
