Abstract
A wideband shaped beam antenna having steep beam edge slopes in one plane is disclosed. An optical multiple beam antenna such as a geodesic lens antenna, a Luneberg lens or a circular folded pillbox, is coupled at selected points to a feed system having a power divider and phasing control. Coupling of the feed system to the optical multiple beam antenna is effected with a power transition having a wide frequency bandwidth and a capability of conducting high power levels. To shape the beam further, selected beams may be amplitude weighted. An aperture control device such as an E-plane sectoral horn, is attached when required, to narrow the beamwidth in the E-plane. By overlapping multiple beams of the optical multiple beam antenna in accordance with the invention, a sector beam having a constant position and constant steep edge slopes over an octave frequency bandwidth is obtained.
