Abstract
The invention concerns a reflector and a satellite antenna system comprising such a reflector. In the satellite antenna system, microwave radiation from one or more feed horns () is emitted at the reflector (), which comprises first and second reflector elements (). Upon reflection of the radiation from the reflector elements (), a distinct beam shape for the reflected microwave energy is generated. The reflector elements () are disposed at a fixed distance from one another so that radiation that passes the first reflector element () strikes the second element. The first reflector element () comprises a lattice structure aimed toward the feed horn, which lattice structure consists of plates () of electrically conductive material, wherein the distance between the plates and the depth of said plates are adapted for reflection of polarization parallel to the plates. The invention is characterized in that the extent of each respective plate toward the second reflector element is chosen so that the transmission losses in the first reflector element are minimized.
