Abstract
A lens system is formed of spaced coaxial hyperboloidal primary and secondary lenses, each having a convex surface described by a hyperboloidal eccentricity equal to the refractive index of the lens with the lenses mounted with their convex surfaces facing each other, and with the lenses having equal beam deviation factors. A feed array is integrated with the secondary lens, with the feed array comprising array elements printed on a substrate which, in turn, is backed by a ground plane. A beam forming and control network is directly connected to the substrate at the ground plane.
