Abstract
The present invention provides antenna feed assemblies that allow the common waveguide portion of an antenna feed assembly to be rotated independent of a fixed communication waveguide. When rotated, the ports of the common waveguide are altered in terms of polarization with respect to signals propagating in the common waveguide, while the predetermined polarization between the ports remains the same. A rotatable coupling between the common waveguide and the fixed communication waveguide allows for communication of signals between the two waveguides, even though their ports are rotated with respect to each other. As such, the polarization of the waveguides associated with the antenna may be reconfigured, even though one of the waveguides remains at a fixed position.
