Abstract
The results of an experimental study of two compound parabolic reflector antennas are reported. The reflectors were designed to have equal beamwidths at two separate frequency bands. The inner region of the reflector was formed as a conducting metallic surface; the outer region was a frequency-selective surface designed to be highly reflecting at the lower frequency band, and transmitting at the higher band. The performance of the compound reflector is compared with that of an equivalent wholly metallic paraboloid
