Abstract

A shaped, segmented multi beam reflector antenna comprising a single reflector segmented into separate surfaces, upper segments having higher focal lengths than the corresponding lower segments, said segments are shaped according to geophysical optics based interactive optimize operating in conjunction with mini max algorithm for simultaneous gain optimization and side lobe cancellation and individual clusters of feed horns for illuminating each of said segments to generate contiguous but inter based beams.
