Design considerations for multi-beam communication satellite's antennas
Abstract
Four uses of multibeam antenna systems are considered. These uses are to increase the energy potential of the radio line in separate spaced areas, to increase the energy potential of the radio line within a wide service area, to increase the energy potential as in the first case with provision for reuse of the frequency spectrum in different areas, and to increase the energy potential as in the second case with provisions for reuse of the frequency spectrum in separate beams. Design characteristics which correspond to these uses are described, and design features are analyzed. The advantages of a double-reflector antenna are explained, and it is concluded that double-reflector antennas are most suitable for use on geostationary communication satellites.
