Study of cluster of hard horns feeding an offset multi-beam reflector antenna for dual band operation at 20/30 GHz

• The study of a multibeam reflector antenna system with hard horn feeds is extended to include the defocusing effects encountered in the actual cluster. This is done by using the ARECIBO code, a reflector program for analysis of multi-reflector antennas. There are many different analysis models for offset reflectors implemented in ARECIBO. The one used for the present study is aperture integration after Fourier series expansion of the aperture field. This is fast and accurate within main beam and first sidelobes, but it is of course slow compared to the BOR model.
