Abstract
An antenna comprises notched semi-elliptical radiators. Each of the radiators has a first substantially planar surface. A ground plane has a second substantially planar surface that is generally parallel to the first substantially planar surfaces of the radiators by a generally uniform spacing. The ground plane has a central axis. Feeding members are adapted for conveying an electromagnetic signal to or from each radiator. Each of the feeding members is spaced radially outward from the central axis of the ground plane. A grounded member is coupled to each radiator and spaced apart, radially outward from the feeding spacer.
