چکیده
|
In this paper a frequency selective surface (fss) as a uwb electromagnetic shield is introduced. 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
