Patent ID: 8283998

Claim:
An antenna feed device comprising: a first waveguide assigned to feed a signal having a first polarization to a dedicated antenna; a second waveguide separated from the first waveguide, and assigned to feed a signal having a second polarization to the antenna; each of the first and second waveguides having substantially an overall L-shape in which at least one section of each L-shaped waveguide is parallel to at least one section of the other L-shaped waveguide, and each L-shaped waveguide comprising: an antenna end terminating in a first plane at one end of the first and second waveguides, and configured to connect the first and second waveguides to an ortho-mode transducer; and a radio end disposed at opposite ends of the first and second waveguides, each radio end terminating at a corresponding single waveguide port disposed on opposing sidewalls of the antenna feed device and configured to connect to respective radio equipment comprising first and second radio units; and the first and second waveguides being formed to connect the antenna and the radio equipment in a substantially compact T-shape interconnection configuration.
