Evaluation of multi-band reflector antennas with frequency selective subreflectors
The design and performance of a dual-screen FSS (frequency selective surface) with double-ring elements are demonstrated. Representative transmission data of this FSS are presented. In addition, the hybrid GO-PO (geometrical optics/physical optics) approach is employed to assess a dual reflector antenna with this FSS subreflector. Representative computed far-field patterns with and without the FSS are given for frequencies of 2.3, 8.4, 13.8, and 32 GHz. As expected, the sidelobe and cross-polarization levels are higher with the presence of the FSS. The peak gain is reduced with the FSS.<>
