Abstract
A high-throughput multi-beam telecommunication antenna is configured to cover a geographical area from a geostationary orbit.It comprises a single reflector and a feed block configured so that each elementary feed is able to generate a different unique beam, the angular separation of any two adjacent primary beams is substantially equal to the angular separation of any two adjacent secondary beams, and the spillover energy losses associated with each source are between 3 and 10 dB, preferably between 3 and 7.5 dB.
