Abstract
A reflector antenna for use on a geosynchronous spacecraft or satellite for providing Earth coverage has a gain or directivity which is two or three dB greater at the edges than at the beam center, to provide coverage with more or less uniform field strength at the Earth's surface. The reflectors may be based on diverging prime focus or offset-feed parabolas, in which case the reflective surfaces of shaped reflectors have, in at least one plane, a central convex region and an “edge” convex region, separated by a concave region. The reflectors may be based on converging prime focus or offset-feed parabolas, in which case the reflective surfaces of the shaped reflectors have, in at least one plane, a concave central region.
