Design aspects of non-regular multibeam coverage for Ka-band broadband communication satellites

Abstract

The paper reports the results of a research project aiming at investigating an innovative non-regular multibeam antenna systems enabling the generation of shaped beams of different size and shape, whose profiles are able to match an assigned irregular lattice of polygonal cells. System analyses demonstrate the superiority of this approach with respect to conventional regular spot-beam and non-regular spot-beam payloads.
