摘要：

The computer-aided optimization of a small, five-wavelength-diameter reflector antenna with a center-supported dipole-disk feed is described. The primary radiation is controlled by using a patented beamforming ring. The efficiency is maximized by controlling and taking advantage of the multiple reflections between the feed and the reflector. This has inspired the name 'resonant reflector antenna. ' The gain from the feed reflector resonances is so large that it compensates almost completely for the approximately 1 dB loss due to center blockage of the aperture.
