PHASED ANTENNA ARRAY Russian patent published in 2003 - IPC

FIELD: microwave engineering; phased antenna arrays. SUBSTANCE: antenna array has microwave-signal distribution system whose input functions as first input of phase antenna array, radiator system, and N double-mode phase shifters each incorporating permanent-magnet polarizer, two absorbers, and phase-shifting section; N outputs of microwave-signal distribution system are connected to first inputs of respective N phase shifters whose output is connected to respective inputs of radiator system. Side-lobe radiation level is reduced due to introduction of polarizer control unit whose first input functions as second input of phased antenna array and its second input, as third input of phased antenna array; each of N outputs of polarizer control unit is connected to control winding of polarizer additionally introduced in each of N double-mode phase shifters and provided with magnetic circuit and control winding. EFFECT: reduced sidelobe radiation. 1 cl, 5 dwg
