PHASED ARRAY Russian patent published in 2010 - IPC H01Q25/02 

FIELD: radio engineering.

SUBSTANCE: device comprises 4K panels of radiators, 4K units of phase changers, 4K liners of wave guide distributing system (WDS), every of which consists of a single manifold wave guide (MW) and branched channels, and also the main distributor made of microwave summator, adding device and directional couplers. In order to achieve technical result, in plane of the main distributor the second MW is introduced into each of 4K liners of WDS, being arranged behind the first MW so that their wide walls lie in the same plane, and branched channels have common sections of wide walls with both MW. Elements of connection in common sections of MW are arranged alternately both with the first and second MW, and outlets of branched channels are arranged pairwise, having elements of connection with the first MW directly, and those having elements of connection to the second MW through phase-aligning sections are connected to inlets of wave guide H-bridges. Outlets of H-bridges are connected to inlets of phase changer units. Main distributor includes four second additional liners of directional couplers, outlets of which are connected to inlets of second MW liners of WDS, and inlets - to outlets of the second microwave summator, functionally to similar first ones.

EFFECT: reduced level of side tabs in differential directivity pattern in plane, where liners of waveguide distributing system are arranged.
