ANTENNA UNIT WITH A CONTROLLED BEAM PATTERN USING A DIELECTRIC LENS Russian patent published in 2020 - IPC H01Q1/28 H01Q3/34 

FIELD: antenna equipment.

SUBSTANCE: disclosed is an antenna unit with a controlled beam pattern for receiving a plurality of falling radio frequency signals under a plurality of angles of incidence, comprising an approximately spherical dielectric lens, aperture unit of waveguides, aperture matrix of switches and radial combiner of apertures. Spherical dielectric lens receives and focuses a plurality of incident radio frequency signals, which provides creation of multiple focused radio-frequency signals on multiple focal points approximately along rear surface of spherical dielectric lens. Aperture block of waveguides is located near the rear surface of the spherical dielectric lens and receives a set of focused radio-frequency signals. Switch aperture array controls electronically beam pattern's beam generated by antenna unit with controlled beam pattern, and switches between plurality of focused radio-frequency signals based on beam electronic control.

EFFECT: technical result is higher efficiency of UAV tracking.
