ON-BOARD HYBRID MIRROR ANTENNA Russian patent published in 2014 - IPC H01Q5/00 

FIELD: radio engineering, communication.

SUBSTANCE: disclosed is an on-board hybrid mirror antenna having a reflector in the form of a cutting from a paraboloid of revolution, having a plane of symmetry which passes through the focal axis of the paraboloid, and a radiating antenna array, the normal of the aperture plane of which, in the plane of symmetry of the antenna, is inclined by an angle β towards the reflector relative to the focal plane of the paraboloid, and consisting of radiators, the number of which is equal to the number of partial beam patterns, where the centres of the radiators are located equidistant from each other, wherein the radiators in the aperture plane of the radiating antenna array are spaced apart in the plane of symmetry of the antenna by a distance which is (cosβ)^-1 times longer than the distance between centres of the radiators.

EFFECT: on-board hybrid mirror antenna which provides zonal coverage of the same territory of the earth's surface at different levels of the directivity factor in the longitudinal and transverse planes.
