Abstract
Lensed antennas are provided that include a plurality of radiating elements and a lens positioned to receive electromagnetic radiation from at least one of the radiating elements, the lens comprising a composite dielectric material. The composite dielectric material comprises expandable gas-filled microspheres that are mixed with an inert binder, dielectric support materials such as foamed microspheres and particles of conductive material that are mixed together.
