Abstract
A multiple beam antenna system including a reflector that is at least partially parabolic in one dimension, a pair of dielectric lenses, and a pair of waveguides. Multiple received beams are received and reflected by the reflector into an orthogonal mode junction which separates signals of a first polarity from signals of a second orthogonal polarity. The signals of the first polarity are forwarded into a first waveguide and the orthogonal signals of the second polarity are forwarded into a second parallel waveguide. A plurality of satellites may be accessed simultaneously thus allowing the user to utilize both signals at the same time. In certain embodiments, each of the dielectric lenses may be of the bifocal type.
