ORTHOMODE SELECTOR OF REFLECTOR ANTENNA FEED Russian patent published in 2024 - IPC H01Q19/00 H01P1/161 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology, in particular to orthomode selectors of reflector antenna feeds. Disclosed is an orthomode selector of a reflector antenna feed, which includes microwave waveguides, four separate microwave ports, wherein two microwave ports are intended for operation in low-frequency range with orthogonal polarisations, and the other two microwave ports are in the high-frequency range with orthogonal polarisations, according to the invention, the device consists of three parts – a lower part, an upper part and a vertical transition, wherein the lower and upper parts divide two high-frequency microwave ports in half – one along the narrow wall of the microwave waveguide, the second along the wide one, and one low-frequency microwave port along the wide wall of the microwave waveguide, wherein the second low-frequency microwave port is located in the upper part on the vertical transition.

EFFECT: simplified design.
