Abstract

High gain, compact and lightweight antennas are highly requested in nowadays communications. To this end, a novel stacked-disk dielectric lens useful for converting linear to right-hand circular polarization (RHCP) or to rotate the field polarization towards a slant-45°, while increasing gain and limiting the overall antenna weight is presented. The lens, of simple manufacturing, is based on a new construction technology which allows an overall weight lens reductions of the order of 90%. Numerical results concerning the gain enhancement and polarization conversion of the field radiated by a horn antenna equipped with the proposed lens are presented and analyzed in detail.
