Abstract
A relatively low cost, easy to install and aesthetically pleasing multi-band, multi-port digital video broadcast from satellite (DVBS) elliptical horn antenna designed as part of a reflector antenna system to simultaneously receive satellite television broadcast signals with circular polarity on two frequency channels. This type antenna may be implemented with a single antenna feed horn with multiple feed horns that may be arranged separately or in one or more integral feed horn blocks. The antennas may be designed to achieve acceptable circular polarity performance over broad and multiple frequency bands through the use of oppositely sloped differential phase differential sections.
