Multiple Beam Torus Antenna Study. Volume 1

Abstract

Offset-fed multiple beam torus antennas (MBTA) provide exceptional wide-angle sidelobe characteristics as a result of a blockage-free aperture. The formation of multiple beams at one or more frequency bands using shared apertures on a fixed reflector structure can result in significant cost savings in a DSCS system in which satellites are constrained to a fixed portion of the geosynchronous arc.
