A new modified Equivalent Circuit Model (M-ECM) enabled Whale Optimization (WO) assisted electromagnetic (EM) approach is presented for an efficient design of a double square loop frequency selective surface (DSL-FSS) based conformal shielding structure. A simple single-layer DSL-FSS is designed, fabricated, and measured to suppress both wireless local area network (WLAN) bands without affecting the rest of the considered spectrum using ECM enabled WO. The analytical and measured results have been found in quite good congruence with each other. The measured transmission coefficient at 2.4 and 5.0 GHz shows suppression of 35 and 38 dB, respectively. Further, the angular stability, polarization insensitivity, and physical interpretation of the DSL-FSS shielding structure are investigated. Finally, the conformal behavior of the structure has been investigated for different bending radius and good agreement between simulated and measured results shows the effectiveness of the aforementioned technique for planar and conformal WLAN shielding applications.
