Abstract
This paper presents a novel and highly miniaturized single-layer frequency selective surface (FSS) for RF shielding. The FSS unit cell is comprised of a meandered crossed dipole structure designed over a low-profile laminate. The FSS achieves a shielding effectiveness of 43 dB at the 10 GHz frequency. Moreover, it provides a fractional bandwidth of 34% for the TE and 46% for TM mode at normal incidence. In addition, it exhibits highly stable spectral responses over a wide range of oblique angles for the vertical and horizontal polarization states. The unit cell is compact and has overall dimensions of 5×5 mm 2 . Hence, the FSS has virtuous potential for EM field suppression applications.
