MULTI-BAND ANTENNA FOR BUNDLED BROADBAND SATELLITE INTERNET ACCESS AND DBS TELEVISION SERVICE

摘要

A multi-band reflector antenna has a main reflector (12) defining a prime focus (11) and a frequency selective surface sub-reflector (50) defining an image focus (40). One or more transmitter or receiver feeds (32, 48) are provided at each of the prime focus and image focus. In one application as a ground satellite terminal, the antenna supports ka-band two-way broadband Internet access bundled with multi-satellite Ku-band direct broadcast television service.
