Design and optimization of H-plane flat shaped dielectric lenses in the 60-GHz band

This paper presents a two-step design methodology with a 2-D modelling approach based on FDTD and Genetic Algorithms to synthesise flat lenses for beam shaping applications. This methodology has been applied to design flat lenses radiating a stable flat-top beam over a 10% bandwidth in H-plane and a nearly omni-directional radiation in E-plane. The results are validated numerically and experimentally in V-band using single-shell and double-shell lenses.
