US Patent 10931364 Satellite payload comprising a dual reflective surface reflector

A satellite payload (20) including a reflector (22), a network (23) of sources (24) and a beam forming network connected to said sources in order to form beams for carrying signals in a first frequency band, called “band B1”, and in a second frequency band, called “band B2”. The reflector comprises two reflective surfaces (22a, 22b) positioned one behind the other in relation to the network of sources and having different curvatures so that each reflective surface generates an image of the network of sources with a different magnification factor. The reflective surface closest to the network of sources is transparent for all the signals carried on the band B2 and is adapted to reflect signals carried in the band B1. The other reflective surface is adapted to reflect signals carried in the band B2.
