Abstract

A novel horizontal polarization sensitive Active Frequency Selective Surface (AFSS) without biasing networks at 2.4GHz WiFi band is presented. The AFSS structure is composed of two mirrored parts and a varactor is set to connect them. Resistors put between the unit cells are used to provide DC connections. No additional biasing networks is required. The structure is sensitive to horizontal polarization wave, which is perpendicular to the unit extending direction. Simulation results show that the structure can offer a wide tunable frequency range from 2.21GHz to 2.71GHz. This behavior makes the AFSS structure suitable for the design of Electronically Steerable Radiator and Reflector Array (ESRRA) antenna at 2.4GHz WiFi band.
