DOUBLE POLARIZATION PLANAR ANTENNA Russian patent published in 2006 - IPC H01Q1/38 

FIELD: microwaves planar microstrip antennas.

SUBSTANCE: antenna can be used in radars, radio introscopes, medical systems, and data receiving and transmitting systems. Length of diagonal of square metal plate-irradiator is chosen as resonant size being equal to radiation wavelength. Anti-phase exciting elements of orthogonal linear polarization are connected to metal plate in pairs and in opposition along orthogonal diagonals of square. Amplitudes of signals received by antenna are equalized at different polarization and level of cross-polarization components of signal induced in orthogonal antenna elements is reduced for electronic scanning range being longer than +-45°.

EFFECT: improved precision of operation; improved reliability.
