Abstract
Two efficient small dual reflector antenna designs are analyzed using the method of moments. One is based on the standard Cassegrain system and the other is a displaced axis design. Both incorporate a low-blockage feed consisting of a dipole radiating in the presence of parasitic elements. In the first case, efficiencies greater than 55% were obtained for 20-wavelength main reflectors; in the second, an efficiency greater than 67% was achieved for a 22-wavelength main reflector
