COMPENSATORY ANTENNA Russian patent published in 2000 - IPC

FIELD: applicable in radio- engineering devices of interference protection in radio-relay and satellite communication systems of the microwave band. SUBSTANCE: the compensatory antenna has an omnidirectional antenna in the form of a parabolic reflector, conductive cone and an antenna feed located on a common axle, it is provided with an additional parabolic reflector, conductive cone and an antenna feed, whose axial symmetry axis is shifted relative to the axial axis of the omnidirectional antenna at a distance equal to a quarter of the wavelength, and the lengths of the supply lines of the antenna feeds differ by a quarter of the wavelength. EFFECT: creation of cardioid space pattern with a decrease of the directive antenna gain in one direction and an increased directive antenna gain in the other directions. 2 dwg
