ABSTRACT:
An antenna of the geodesic lens type is disclosed. The antenna structure is based on optical principles and provides wide angle scanning of a narrow base. The exact shape of the domed structure is found by solving an integral equation and results in nearly perfect focus in the scan plane. A dielectric loaded flared horn is attached to the feed circle of the domed structure and focusses energy in the plane orthogonal to the scan plane. The cross sectional shape of the outer curvature of the dielectric is elliptical. Since the structure is circularly symmetrical, constant beam shape, wide angle scanning, and a rapid scan rate are possible.
