ABSTRACT:
A dome antenna including a dome of solid dielectric material and scannable feed array positioned in the base plane thereof. The dielectric material of the dome constructed to provide a dielectric constant that varies with the perpendicular distance from the base plane. Rays emanating from the base plane are continuously refracted within the dome and refracted at the surface thereof, the interface with free space, to accomplish sufficient a scan angle amplification for scanning beam to the horizon and below.
