Abstract
A device and method are described for duplex satellite communication over a single satellite antenna. A satellite ground terminal may utilize a frequency-selective surface module including a frequency-selective surface as a subreflector acting as a frequency diplexer to separate signals received and/or transmitted by a first feed and a second feed of a satellite ground terminal, where each feed has a separate antenna horn. The frequency-selective surface module may be used in combination with a second subreflector such that a first feed and a second feed of the satellite ground terminal are implemented on the same side of the frequency-selective surface module.
