DOUBLE-REFLECTOR ANTENNA Russian patent published in 2013 - IPC H01Q19/18 

FIELD: radio engineering.

SUBSTANCE: double-reflector antenna includes main reflector (1) with parabolic generatrix, auxiliary mirror (6) with elliptical generatrix and irradiator (5). Double-reflector antenna is provided with polarisation converter in the form of two plates (2) and (3), in at least one of which there are slots of rectangular section, which form waveguide channels (when being combined with each other) of polarisation converter with a partition wall, on the side surfaces of which there is output and input waveguide flanges; at that, polarisation converter is fixed on the side of input flanges on main reflector (1), and irradiator (5) made in the form of a conical horn is installed on output flange of polarisation converter.

EFFECT: structural and technological simplification; enlarging functional capabilities at simultaneous improvement of reliability.
