Frequency Selective Surface for the blocking of multiple frequency bands

A frequency selective surface (FSS) to block the multiple frequency bands has been proposed. As our target frequency bands, Korean cellular mobile communication (800 MHz band), PCS (1.8 GHz band), and 2.4 GHz ISM bands are selected. By applying the proposed design and tuning procedure, we can successfully tune the resonance center frequencies of our FSS where we want to place. As our future work, we are improving our structure to obtain wider bandwidth and stable angular sensitivity, simultaneously
