Abstract
A reflector antenna system having a diplexer for providing isolation between transmitted and received signals, which eliminates the need for a diplexer to be inserted into the waveguide or coax transmission line coupling the antenna system with an external antenna electronics subsystem. The antenna system includes a main reflector to which is coupled a low effective dielectric tube. Transmit and receive feedhorns are supported within the tube. A hyperboloidal receive bandpass filter is supported in front of the receive feedhorn and a hyperboloidal transmit bandpass filter is disposed in front of the transmit feedhorn. The receive bandpass filter allows the received signal to pass therethrough but blocks the transmitted signal from the transmit feedhorn. Conversely, the transmit bandpass filter reflects the received signal received from the subreflector surface back towards the receive feedhorn while allowing the transmitted signal from the transmit feedhorn to pass therethrough.
