Abstract
This paper describes a multibeam antenna system which produces transmit and receive beams simultaneously using multiple-feed-per-beam (MFPB) scheme. Compared with the current widely used mutibeam antenna with more than two apertures, the proposed antenna configuration required only one main reflector aperture. Combined with a frequency selective sub-reflector (FSSR), a transmit feed array and a receive feed array, this antenna system can produce equalized beams to cover the desired area. Based on the beam deviation factor (BDF) of the parabolic reflector, a simple and accurate design process is proposed. And a Ka-band multibeam antenna is designed, and the preliminary results are simulated. The simulated results show that the multibeam antenna using one reflector aperture is feasible.
