ABSTRACT:
A reflector-feed assembly for a reflector dish antenna system includes a feeding waveguide and a reflector plate. The feeding waveguide is operable to support the propagation of a signal therethrough, the feeding waveguide having a major axis along which the signal is propagated, and one or more apertures operable to pass the propagating signal therethrough. The reflector plate is coupled to the feeding waveguide, and extends along a major axis which generally orthogonal to the major axis of the feeding waveguide. The reflector plate includes one or more reflecting surfaces which are positioned to reflect signals passing through the one or more apertures, the one or more reflecting surface extending at an acute angle relative to the feeding waveguide major axis.
