A shaped reflector antenna, illuminated by a corrugated horn, has been designed, fabricated, and tested. The test results show that the feed blockage and the strut support blockage cause performance degradation. The deficiency can be corrected by using a shaped lens, illuminated by a corrugated horn. The lens antenna avoids both the feed and the strut blockage. The lens surface is shaped to provide a nearly uniform coverage over a +or-90 degrees cone. A good axial ratio at 44 GHz is achieved by designing the corrugated horn with nearly equal E- and H-plane patterns.<>
