PHASED ANTENNA ARRAY WITH TWO INDEPENDENT BEAMS AND CONTROLLABLE POLARIZATION IN CUMULATIVE BEAM (VARIANTS) Russian patent published in 2006 - IPC H01Q3/26 H01Q21/00 

FIELD: antenna UHF equipment engineering, possible use in pass or reflective phased antenna arrays with electric scanning of beam for various purposes, including that in radiolocation stations for finding, tracking and determining coordinates of targets.

SUBSTANCE: phased antenna array contains emitters, controllable phase shifters, phase shifters excitation system, connected to transmitting-receiving channels, and system for controlling the beam, while as emitters, longitudinal type emitters are utilized, meant for operation on orthogonal polarizations of signal being emitted and signal being received, each one of which has two outputs decoupled by high frequency, appropriate for two orthogonal polarizations, one geometry axis for both polarizations of signal being emitted and signal being received, coinciding phase centers and coinciding direction diagrams, while excitation system consists of two irradiators or feeder distribution system, two circulators, connecting receiving and transmitting channels, two switches of type of operation and an adder.

EFFECT: creation of adaptive phased antenna array, which can generate two independently controlled beams with orthogonal polarizations of UHF field and amplification coefficient, appropriate for full coefficient of surface usage by each beam, may form cumulative beam with double emitted power while providing control in this mode over different polarization types, while all three beams work simultaneously on one and the same frequency of working range.
