N2 - Parabolic reflectors and, to some extent, dielectric lenses are typical candidates for high-gain microwave and millimeter wave antenna systems. The latter are sometimes used as alternatives to reflectors in situations where the aperture blockage caused by the feed antenna becomes a problem. Conventional dielectric lenses have curved profiles, typically convex or plano-hyperbolic, and they suffer from limitations of relatively high weight and transmission losses. In addition, it is not easy to fabricate them in a cost-effective manner.
