Sažetak
A fast and accurate CAD tool for synthesizing layered circular-cylindrical dielectric lens antennas fed by pyramidal horn antennas has been recently developed. It is based on the G1DMULT (Green’ s functions for 1D MULTilayered structures) algorithm which presumes that circular-cylindrical lenses are of infinite length. In this paper we study the effects of length truncation upon the lens radiation characteristics and define the range of validity of G1DMULT. Two height reduction techniques are also proposed. It is shown that they allow reducing the antenna size by a factor two, while preserving fan-beam radiation patterns and beam scanning capabilities.
