On the Design of Conformal Radomes for Beam-shaping of Antennas

In this paper, we describe a systematic approach to synthesizing conformal radome., comprised of phase shift structures (PSSs), which is designed to reshape the primary beam in a desirable way. The reshaping technique proposed herein is based on the application of Generalized Law of Refraction (GLR). The design procedure for the beam-shaping conformal radome is discussed and a design example is presented to demonstrate that the reshaping technique can be used to successfully modify the primary beam of a feed horn, placed behind the radome, to a flat-top radiation pattern, which was our desired goal.
