Convoluted FSS Structure for Shielding Application In X-Band Frequency Response

Abstract

A compact single-layer frequency-selective surface (FSS) covering X-band frequency range for shielding application is presented in this study. The proposed FSS structure, constructed with a convoluted element printed on both sides of FR4 material, exhibits band-stop response covering a frequency spectrum of 8–12 GHz at 10 dB level of insertion loss. The designed FSS provides polarization-independent performance and good angular stability. The simulated result and the measured results seem to be in a good agreement.
