Wide angle multibeams

A method using a multibeam antenna for generating multiple spot beams, the method comprising:

• providing at least two antenna reflectors,
• wherein each of the at least two antenna reflectors has its surface shaped from a parabolic shape in order to broaden and shape the reflected spot beams;
• and
• using a plurality of antenna feeds, for each of the at least two antenna reflectors, to radiate radio frequency (RF) energy onto the at least two antenna reflectors in order to produce the multiple spot beams,
• wherein each of the at least two antenna reflectors is configured to contribute, and to be the sole reflector that contributes, to each spot beam of a set of adjacent spot beams of the multiple spot beams.

• providing a plurality of antenna feeds for each of the at least two antenna reflectors;
• providing an antenna sub-reflector for each of the at least two antenna reflectors;
• and
• using the plurality of antenna feeds, for each of the at least two antenna reflectors, to radiate radio frequency (RF) energy onto the antenna sub-reflector associated with the antenna reflector for the plurality of antenna feeds, wherein the RF energy is reflected from the antenna sub-reflector onto the antenna reflector for the plurality of antenna feeds in order to produce the multiple spot beams,
• wherein each of the at least two antenna reflectors is configured to contribute, and to be the sole reflector that contributes, to each spot beam of a set of adjacent spot beams of the multiple spot beams.
