A Compact Polarization Selective Surface (PSS) for Dual-Band Wi-Fi and Wi-Max Shielding Applications

This article reports on a compact, single layer, and angularly stable Polarization Selective Surface (PSS) for dual-band Wi-Fi and Wi-Max shielding applications. The unit cell consists of a square loop loaded with stubs and rectangular loops. Unlike conventional FSS, the proposed unit cell generates two stopbands by rotating it 90° without the use of any active components for polarization selective operation. A finite prototype containing 20 × 16 elements is fabricated and tested for verification. Measured results show good agreement with the simulations. The performance of the proposed PSS establishes its application as polarization converters and in wave generators.
