Abstract:
A tri-passband three-dimensional frequency selective surface(3D FSS)with high selectivity and small band ratios is designed based on the topology of the microwave filter. The unit cell of the proposed 3D FSS consists of an air-filled square waveguide and a cuboid dielectric block,and three concentric square loops are printed on both the top and bottom layers. Due to electromagnetic coupling between the resonant elements on both the top and bottom layers,original single resonant mode will split into even- or odd-resonant modes,multiple transmission zeros/poles are introduced,three second-order passbands and stopbands are achieved,and its frequency selectivity is greatly improved. Square loops with very close sizes are designed to realize small band ratios. To understand the working principle of the proposed 3D FSS,the surface current distributions at the frequencies of transmission poles are investigated. Meanwhile,the fabrication and measurement methods of the proposed 3D FSS prototype are discussed. According to the literature comparison,the proposed 3D FSS has the advantages in high selectivity,small band ratios,good angular stability,dual polarizations and no grating lobes.
