Modeling and Design of Reconfigurable Multi-Band Frequency Selective Surface

In this paper, we have proposed a reconfigurable multiband cell frequency selective surface with high selective frequency performance. A single layer ring loop, square loop and cross dipole elements with four switch form the reconfigurable multiband frequency selective surface (RFSS) unit cell proposed in this paper. The cross dipole structure is combined with the square loop and ring loop components to provide multi-band function. The proposed structure of RFSS can be used for many applications to pass or reject different frequency bands below 12 GHz. The proposed design is simulated and optimized using commercially available Ansys HFSS software.
