An antenna (11) comprises notched semi-elliptical radiators (26, 28, 126, 128). Each of the radiators (26, 28, 126, 128) has a first substantially planar surface. A ground plane (14) has a second substantially planar surface (29) that is generally parallel to the first substantially planar surfaces of the radiators (26, 28, 126, 128) by a generally uniform spacing. The ground plane (14) has a central axis. Feeding members (32) are adapted for conveying an electromagnetic signal to or from each radiator. Each of the feeding members (32) is spaced radially outward from the central axis of the ground plane (14). A grounded member (34) is coupled to each radiator and spaced apart, radially outward from the feeding spacer (32). |
