Equivalent circuit model of the frequency select surface is given, and a feasible method of design of multi-pass frequency selective surface is discussed. Based on the method, a novel frequency selective surface with two pass bands is presented. The simulation results indicate that, the center frequencies of the bands are at 2.95GHz and 8.6GHz, and the 3dB bandwidth is 3.5% and 5%. Also the center frequencies and the transmittance of the pass bands are affected less by the polarization direction and incident angel of the wave, or the structure exhibits a great filter feature as a frequency selective surface.
