a Compact Size FSS Unit Cell Design For UWB Filtering and Shielding Applications

In this paper, a Frequency Selective Surface (FSS) Unit Cell (UC) for UWB filtering and Shielding applications is presented. The suggested UC is designed on an FR-4 substrate with dielectric constant $\varepsilon_{r}$=4.3 with a compact size of 6 x6mm

. the designed structure operates on a very wide frequency band of14 GHz (from 2 to 16 GHz) with very high Shielding effectiveness (maximum SE of 49.2 dB at 9.9 GHz) through the same operating band. The proposed design was discussed with simulations and good results were obtained.
