Abstract
A feed assembly and feed support arm for parabolic antennas with circular or linear polarization is provided in a streamlined configuration. The feed assembly contains a septum polarizer with parallel transmit and receive ports, or a similarly configured ortho-mode transducer. Through a common waveguide transition, the ports connect to transmit and receive filters joined together in parallel to form a square-profile structure that serves as the feed support arm. The receive filter terminates in a low noise block downconverter while the transmit filter connects to a waveguide flange at the base of the reflector, which is the output port of an up-converter/power amplifier mounted behind the reflector. Alternatively, the power amplifier is integrated into the feed support arm, connecting to the rest of the transmitter behind the reflector.
