PHASED ANTENNA ARRAY WITH ELECTRONIC SCANNING IN ONE PLANE Russian patent published in 2013 - IPC H01Q25/02 

FIELD: radio engineering.

SUBSTANCE: phased antenna array with electronic scanning in one plane includes power distribution device made in the form of two combined metal plates (1) with slots on mating surface of equal depth, which form when being combined two main E-sectorial horns (2) and 2N receiving E-sectorial horns (3) located in their aperture. Inputs of the main E-sectorial horns (2) are connected to outputs of additional waveguide power divider (4) made in the form of 2T-piece. Outputs of power divider are loaded on waveguide phasers (5), to the outputs of which radiators (6) are connected. An individual design of assemblies, their location and connections are specified in additional claims.

EFFECT: possible design of phased antenna arrays with arbitrary amplitude distribution; simple realisation in millimetre wavelength range; possible design of single-pulse phased antenna array.
