PLANAR ANTENNA WITH CONTROLLED POLARISATION CHARACTERISTIC Russian patent published in 2011 - IPC H01Q13/00 

FIELD: physics.

SUBSTANCE: basic radiating elements of a two-dimensional array lie in nodes of a square grid whose period is of the order of the wavelength in a planar dielectric waveguide (3), wherein the width of central orthogonal series of basic radiating elements have dimensions of the order of the period of the array, and linear arrays (1, 2) of auxiliary radiating elements which form the excitation device (5) lie orthogonal to each other, having a common central input (9), and the screen (4) is fitted with a crossed slot (8) lying under central basic radiating elements of the two-dimensional array.

EFFECT: operation of the antenna in normal radiation mode with controlled polarisation and a wider operating frequency band.
