MULTI-WAVE ANTENNA (VERSIONS) Russian patent published in 2017 - IPC H01Q15/16 

FIELD: physics.

SUBSTANCE: multi-beam antenna comprising a focusing system consisting of a concave mirror, an irradiation device for irradiating a concave mirror consisting of a two-dimensional array of irradiators located at a distance from the concave mirror and overlapping the projection zone of the rays at that distance and a beam forming system. The irradiation device comprises at least one subarray of irradiators providing one beam in a predetermined direction. For each such beam, the beamforming system provides such amplitude-time parameters of the transmitted signal for each illuminator in its subarray in order to form a non-planar wave front equidistant through the concave mirror to the plane wave front of such a beam. The radiating surface of the array of irradiators is outside the self-intersection zone of nonplanar wave fronts.

EFFECT: providing a large number of active beams.
