Abstract :
The novel design of a circular waveguide feed structure for use with a Direct Broadcast Satellite (DBS) reflector dish that can operate in two frequency bands for HDTV, is presented. The dimensions of the waveguide are calculated from theory. The antenna is modelled and simulated in CST Microwave Studio™ with the addition of a dielectric to shrink one of the waveguides to reduce both size and cost. This antenna feed will have applications for those people in the UK and Ireland who do not receive a quality landline broadband service of at least 2 Mbps. The new DBS design will permit much greater bandwidth for multichannel HDTV and broadband duplex at greater than 2 Mbps via satellite to the home.
