PHASED AERIAL WITH CIRCULAR SPATIAL POLARISATION Russian patent published in 2009 - IPC H01Q21/00 

FIELD: physics; radio.

SUBSTANCE: invention concerns high-frequency antenna systems. The phased array antenna (PAA) with circular spatial polarisation represents the multilayered panel with n - meshes of the square section, forming flared radiators. The present PAA is supplied with a two-network distributive guided-wave system. Internal cavities of through meshes of panels of the first three layers form a uniform volume grid with si - meshes (n - any integer multiple to four), their cavities form the flared radiators representing wave guides of a square cross section with apertures in the form of megaphones with a slope angle of internal walls making 15-25 degrees, from a mesh axis; thus the flare side length at the aperture underplate makes 0.86-0.91 L of mesh side length at height of a flare (0.3-0.4) L. Power dividers in the form of local wave guide contraction simultaneously carry out function of the quarter wave transformer. There are transition angled bends in the form of metal parallelepipeds on exits of wave guides after a divider.

EFFECT: provision of simultaneous transceiving of radio signals with right and left circular polarisation in a frequency range of 10,7-12,7 GHz with high amplification factor.
