Compact, Directive and Loss Free mmW Antenna

A directive planar surface wave launcher enables an efficient excitation of a guided surface wave in the grounded dielectric slab. Conductor losses are minimized by the reduction of conductor elements and by the introduction of an isolation film or an air gap between the dielectric slab and the ground plane. The curved ground plane allows to radiate the waves into free space without strong reflections.
Finally, a planar lens placed directly on top of the dielectric slab shapes/focuses the wave in the H-Plane.

Features
