In this article, a reconfigurable frequency selective surface (RFSS) with a wide reconfigurable passband and angular stability property is proposed. In this design, The RFSS consists of three metallic layers and two thin dielectric substrates with metallic via holes. Tunable electromagnetic characteristics are achieved by loading varactor diodes. Because of the symmetry of the structure and the insertion of metal via holes, the RFSS is insensitive to the incidence of TE and TM polarization, thus improving angular stability. The proposed RFSS can be tuned from 5.4 to 15.96 GHz when the incident angle ranges from 0° to 60°. The RFSS was made and tested to verify the proposed design. The proposed RFSS has good performances, which are verified by simulation and measurement results.
