Abstract

Satellite multibeam antennas are becoming increasingly popular for satellite applications. Their main attractions are due to higher gain, and smaller beamwidth for interference rejection and frequency reuse. These characteristics become more advantageous as the frequency goes up. In the paper, an experimental millimetre-wave receive multibeam antenna with low side lobe levels and nulling capability is presented. Experimental results are given.
