Electromagnetic shielding by frequency selective surface
This paper presents a dual-layer Frequency Selective Surface (FSS) that exhibits a significantly wide stop-band of 9.5 GHz in 4.91-14.41 GHz range. It demonstrates more than 35 to 45 dB attenuation that can be effectively used to shield X-band satellite signals and in other low-profile stop-band and...

| Summary: | This paper presents a dual-layer Frequency Selective Surface (FSS) that exhibits a significantly wide stop-band of 9.5 GHz in 4.91-14.41 GHz range. It demonstrates more than 35 to 45 dB attenuation that can be effectively used to shield X-band satellite signals and in other low-profile stop-band and shielding applications. The unit-cell generates significant 98.3 bandwidth percentage. The design consists of two symmetrical patterns printed over the surfaces of FR4 layers. Due to simple schematics, it bears a low fabrication cost. |
