DOUBLE-POLARIZED ARRAY Russian patent published in 2006 - IPC H01Q21/06 

FIELD: microband microwave arrays for use in radars, microwave imagers, medical apparatuses, information receiving and transmitting systems.

SUBSTANCE: the radiators are positioned in the points of the hexagonal grid with a horizontal pitch determined by the required band of absence of the combination lobes in the directivity pattern, antiphase exciting elements of orthogonal linear polarizations are connected to the plate in antiphase on the orthogonal diagonals of the square.

EFFECT: reduced level cross-polarized components of the signal induced at polarizationally orthogonal outputs of the array for the band of electronic scanning exceeding +-45 deg.
