Abstract
A multi-wave-reflector antenna dish simultaneously receives signals from different satellites. The antenna dish comprises a reflector with a superquadric projected aperture and a plurality of LNBF modules. The reflector is formed through process including, projecting the superquadric on the paraboloid, projected aperture cutting and surface distortion of the aperture based on the generalized diffraction synthesis technique. In addition to reflecting signals from satellites, it also generates focusing waves sharing similar radiation patterns and horizontal gain with incoming waves on the focal plane, finally to be received by the LNBF modules.
