The planar lateral wave antenna

A novel planar lateral wave antenna concept that promises impedance matching over factor a one to three bandwidth, very high efficiency, and high directivity in one plane in presented. The structure realizes a planar elliptical dielectric lens antenna for focusing the beams in the H-plane. A broad band feed launches wave within a parallel plate waveguide region, filled with dense dielectric. These waves realize a directive and almost frequency independent aperture field configuration, exploiting a novel lateral wave propagation mechanism.
