Abstract
A method and system are disclosed for wide angle multibeam antennas. The method and system involve a multibeam antenna system for generating high performance multiple spot beams. In one or more embodiments, the multibeam antenna system includes an oversized antenna reflector and a plurality of antenna feeds. The oversized antenna reflector has its surface shape optimized from a normal parabolic shape in order to broaden and shape the reflected spot beams to improve antenna performance. In addition, the diameter of the oversized antenna reflector is greater than ((100*λ)/δ), where λ is the wavelength in inches and δ is the beam to beam spacing in degrees. In some embodiments, the ratio of the focal length of the oversized antenna reflector to the diameter of the oversized antenna reflector (F/D) is greater than 0.7. In at least one embodiment, the system further includes an antenna sub-reflector.
