Abstract

An FSS based electromagnetic (EM) shield for 5G, X-band and Ku-band indoor shielding applications is proposed in this manuscript. This shield offers a tri-band and polarization-insensitive behavior. A wide rejection bandwidth (10 dB) of atleast 1400 MHz, 3200 MHz and 1100 MHz for 5G, X and Ku-band is observed. The design incorporates meandered square loop (MSL) and slitted Jerusalem cross (SJC) provides shielding for the targeted bands while offering excellent incident wave angular stability up to 75 degrees. In addition to this, a lumped circuit model, metamaterial (MTM) characterization and finite element boundary integral equation (FEBI) investigations are also performed to evaluate and confirm the performance of the FSS. Dual meta-material characteristics are observed including ENG (epsilon-negative)/MNG (mu-negative) while achieving at least 30 dB shielding effectiveness (SE).
