Abstract
A multi-beam antenna includes a plurality of radiating elements and a lens that is positioned to receive electro-magnetic radiation from at least one of the radiating elements, the lens comprising a composite dielectric material. The composite dielectric material comprises a foamed base dielectric material having particles of a high dielectric constant material embedded therein, the high dielectric constant material having a dielectric constant that is at least three times a dielectric constant of the foamed base dielectric material.
