A Dual-Band Frequency Selective Surface Design for Satellite Applications

In this paper, a single layer dual-band reflective frequency selective surface (FSS) with incident angle up to 60° is designed. This FSS design can be used as a sub-reflector in the design of reflector antennas for satellite communication applications. The designed FSS structure consists of a center placed four arm structure for Ku band, two-legged structures placed in corners and four leg structures placed in each quadrant used for Ka band. The proposed FSS structure is capable of reflective electromagnetic waves in Ku-band (14.1-16 GHz) and Ka-band (29.2- 36.8 GHz). The simulated return loss over the Ku band is less than 0.6 dB when the incident angle is between 0° and 60° for both TE and TM polarizations. On the other hand, the Ka band reflection loss is less than 0.5 dB when the incident angle is between 0° and 60° for both TE and TM polarizations. Obtained results are compared with similar works and discuss.
