Abstract
A dual polarized reflector antenna assembly, provided with a reflector dish coupled to a feed hub with a feed port there through; a transceiver support bracket coupled to a backside of the feed hub; a circular to square waveguide transition coupled to the feed port; a square waveguide coupled to the circular to square waveguide transition; an OMT coupled to the square waveguide; the OMT provided with an OMT intersection between a square waveguide and a pair of rectangular waveguides oriented at ninety degrees to one another, an output port of each rectangular waveguide arranged normal to a longitudinal axis of the dual polarized reflector antenna assembly. Alternatively, a circular waveguide may be applied between the feed port and the circular to square waveguide transition, eliminating the square waveguide, or the rectangular waveguides may be extended longitudinally, also eliminating the square waveguide.
