PHASED ARRAY Russian patent published in 2012 - IPC H01Q25/02 

FIELD: electricity.

SUBSTANCE: phased array (PA) comprises four quadrants of aperture and the main distributor (1), having three inputs and four outputs. Each of aperture quadrants comprises a distributor of a column (2) with N outputs and N distributors of lines (3) with microstrip phase changers (4) installed on them. Distributors of lines are combined pairwise with group radiators into nodes. Distributors of lines (3) comprise coaxial-strip transitions, multichannel power dividers, made as circular power dividers on the basis of a symmetrical strip line with a suspended substrate with absorbing elements of circular dividers in the form of tubular microwave resistors, directly installed microstrip phase changers (4), every of which with its input is connected to one of the outputs of the multichannel power divider, and with the output - to one of strip group radiators, made on the basis of an asymmetrical strip line with a suspended substrate, and are combined with distributors of column (2) by coaxial lines. Column distributors are structurally combined with the main distributor.

EFFECT: reduced weight and dimension characteristics of a phased array during its operation in low-frequency ranges.
