Corrugated dual band waveguide and EM signal generators — An overview for future satellite communication possibilities

In this paper we present an overview of work carried out to design, manufacture and test a corrugated waveguide section for a feedhorn, suitable for a reflector antenna to receive digital satellite television. A system has been designed to carry circularly polarized waves in a two concentric waveguide system. Waveguide transitions are also designed, constructed and tested in linear polarization to permit the testing of the corrugated section. Initial results show that the signal generators measured performance is comparable to simulation results. We aim to focus on improving these results with a target return loss performance of -20dB across the band of 19.7-20.2 GHz.
