Abstract :
Complete radiation pattern of a focus-fed offset parabolic reflector antenna is presented. Forward radiation and wide-angle radiation is calculated using the geometrical theory of diffraction. Effects of the offset angle and the feed pattern asymmetry on the cross-polar isolation are presented. Design criteria of an offset reflector satisfying the WARC-DBS requirements for receiving antenna, and for a given feed radiation pattern are presented. It is also shown how to determine the antenna noise temperature experimentally, using direct satellite signal.
