PHASED ANTENNA ARRAY Russian patent published in 2014 - IPC H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and can be used in microwave antenna engineering in phased antenna arrays employing a monopulse bearing method. The phased antenna array consists of radiator panels, phase changer units, WRC lines and a main distributor, having a microwave adder, four main lines of directional couplers, a summation device, four additional lines of directional couplers, a directional coupler, phasing sections and matching loads, wherein for operation at different frequencies, each of the four main lines of directional couplers of the main distributor are made with two main waveguides, arranged parallel to each other such that branched waveguide channels alternately have common wide walls with coupling elements in them with either main waveguide, wherein the first and second main waveguides are linked at the inputs by a balance bridge, inputs of which are two independent inputs of the lines of directional couplers.

EFFECT: broader functional capabilities by enabling operation of both the whole antenna and independent operation of separate quadrants of the antenna while operating at different frequencies.
