Abstract  To solve the size limitation problem of the frequency selective surface in engineering application, a novel miniaturized frequency selective surface (FSS) was proposed. The miniaturized size was achieved by increasing the values of equivalent inductance and capacitance of the unit cell. Compared to previous miniaturized structures, the proposed FSS had better miniaturization performance with a unit cell of only dimensioned as 0.079λ0×0.079λ0, where  λ0 represented the wavelength of the resonant frequency. The high stability of the FSS was gained by a high degree of symmetry of the new structure. The simulation and measurement results showed that this structure kept the excellent transmission stability with respect to different incidence angles and modes of plane wave.

Key words： frequency selective surface      miniaturization      angle stability      polarization stability

基于方环型频率选择表面的小型化设计

为解决频率选择表面（frequency selective surface, FSS）在工程应用中的尺寸限制问题，提出了一种新型小型化FSS. 新结构通过增大方环谐振单元的等效电容和等效电感实现频率选择表面的小型化，与前人提出的小型化FSS比较，该新型FSS单元的尺寸更小，仅为0.079λ0×0.079λ0（λ0为阻带中心频率点对应的波长）.另外，新结构的高度对称性确保了其性能的高稳定性，仿真和实测结果表明：新结构对不同角度和不同模式的入射波保持了十分稳定的传输特性．
