A Single-Layer UWB Frequency-Selective Surface With Band-Stop Response

A single-layer compact frequency-selective surface (FSS) covering ultra-wideband application is presented in this letter. The proposed FSS constructed with convoluted elements exhibit band-stop response covering a frequency spectrum of 3.1-13.3 GHz at 10 dB. The prototype of the FSS is fabricated and the measured results seem to be in good agreement with the simulated result. Also, the designed FSS manifest polarization independent performance and good angular stability.
