In trhis paper, commercial Ku band ground terminal antennas for satellite reception, such as DirecTV's, have played a major role in the digital revolution. Another step further, commercial Ka and Ku band Tx/Rx terminals are evolving around applications requiring data rates from 100Kbps to a few 100Mbps. Examples of these applications include high speed internet, telemedicine, entertainment on- demand, and remote video monitoring, just to name a few. To meet these requirements, Raytheon has developed a family of commercial Ka and Ku band dual-offset shaped reflector antennas with three diameters, including 65cm, 75cm, and 95 cm.
