Multi-beam-reflector dish antenna system and method for production thereof

摘要

A multi-beam-reflector dish antenna system and a method for production thereof are disclosed. Signals from different satellites are simultaneously received using a single compound LNBF module. The multi-beam-reflector dish antenna system includes a reflector with N-th order projected aperture and a single compound LNBF module constituting multiple LNBF units. The reflector is formed by projected aperture cutting and surface distortion of the aperture in accordance with the method of analysis and synthesis. In addition to reflecting signals from satellites, it also generates focused waves sharing similar radiation patterns and horizontal gain with incoming waves on the focal plane to be received by the compound LNBF modules.
