Abstract
A novel dual-band feed for reflector antennas is presented. This feed is a combination of a novel circular Eleven feed for C band and a compact choke horn for Ku band. The combined feed has been characterized in terms of total feed efficiency of reflector antenna and coupling coefficient of C and Ku bands (< -18 dB) over all operating frequencies. An experimental model has been manufactured and measured. The measured results agree well with the simulated ones. The dual-band feed is compact in size and can be a good candidate for satellite terminals and other applications.
