Abstract
A convoluted meander line integrated cross dipole metallic structure with a dual-bandstop feature is presented in this manuscript. The investigated frequency-selective surface (FSS) exhibits the bandstopping characteristics for the Bluetooth (2.4 GHz) and WLAN (5.5 GHz) applications with a miniaturized unit cell size of 9.7 × 9.7 mm2. The proposed design has a polarization insensitivity feature for the TE and TM polarized waves’ incidents at 0°–60° with an interval of 15° angle. The equivalent circuit model of the presented FSS unit cell is also discussed and their limped element values are presented. The FSS design has a compact size which makes it favorable for low-profile band-filtering systems and multipath EM wave’s insensitivity. The suggested FSS configuration has good correspondence with modelled and measured results.
