The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C elements and a ring at two sides of a FR4 board with 3.2mm thickness, dielectric constant of 4.4, and loss tangent of 0.02. The structure has a 24×36 elements with dimensions of 288×432mm. Also the simulation and measurement results are in good agreement.}, keywords = {FSS,Shielding Effectiveness,UWB}, url = {https://jce.shahed.ac.ir/article_459.html}, eprint = {https://jce.shahed.ac.ir/article_459_8dbf2d9028f66bb8273916715fd65164.pdf} }
