Abstract
A microwave lens broadens the radiation pattern of an antenna feedhorn so as to result in improved illumination of the reflector surface. The lens, constructed of dielectric material in the shape of a half-torus, provides feed radiation patterns suitable for use with deep paraboloidal reflectors, typically ones having focal-length-to-diameter ratios between 0.25 and 0.35.
