Patent abstract
An antenna may include a primary reflector having a ring focus; a feed body along an axis of the primary reflector, the feed body including a circular waveguide coaxial with the axis of the primary reflector; a sub-reflector disposed facing an end of the circular waveguide; and a generally cylindrical stem extending from a center of the sub-reflector into the circular waveguide to form a section of annular waveguide. A sub-reflector support may mechanically connect a perimeter of the sub-reflector and an outside surface of the feed body. The sub-reflector, the stem, and the feed body may be collectively configured to couple microwave energy between the annular waveguide and the primary reflector.
