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...
The design, simulation and fabrication of a dual band waveguide structure for the direct broadcast satellite (DBS) market is presented. Using two frequency bands under study; 19.7–20.2 and 29.5–30 GHz, we have created a corrugated waveguide structure with a second higher band waveguide nested inside the outer waveguide. The design and simulation was carried out using CST's Microwave Studio 2010 Suite...
The design and simulation of a dual band, coaxial waveguide feedhorn structure for a satellite reflector dish is presented using CST's Microwave Studio™. The feedhorn operates on the satellite television frequencies, commonly referred to as the Direct Broadcast Satellite (DBS) frequencies of, 10.7-12.75, 19.7-20.2 and 29.5-30 GHz. The feedhorn structure consists of two separate waveguides that are...
