Abstract
The present invention discloses a method for generating multiple antenna beams and a system for generating multiple antenna beams. The system comprises a first reflector surface that has a primary and at least a first auxiliary surface, and a second reflector surface, and also comprises first, second, and third feed horns. The first feed horn illuminates the primary surface with radio frequency (RF) energy, the second feed horn illuminates the auxiliary surface with RF energy, and the third feed horn illuminates the second reflector surface with RF energy. The first feed horn and third feed horn are removed from an axis of symmetry of the first auxiliary surface. The method comprises illuminating a primary portion of a first reflector surface with radio frequency (RF) energy from a first feed horn, illuminating an auxiliary portion of the first reflector surface with RF energy from a second feed horn, illuminating a second reflector surface with RF energy from a third feed horn, wherein the first feed horn and third feed horn are removed from an axis of symmetry of the auxiliary portion of the first reflector surface.
