【摘要】 本文设计了一款具有较好的极化稳定性和角度稳定性的带通小型化频率选择表面。该FSS结构基于优化后的方螺旋图形,单元尺寸仅为0.062λ₀×0.062λ₀。通过HFSS软件的仿真计算,该FSS在3.86GHz附近形成了一个明显通带,在满足插入损耗不高于3dB的前提下,通带带宽为490MHz。当不同极化的电磁波以不同角度入射时,FSS传输曲线呈现出很好的稳定性。更多还原

【Abstract】 In this paper,we design a band-pass miniaturized frequency selective surface with good polarization stability and angle stability.The FSS structure is based on the optimized square helix pattern,and it has a small unit size of 0.062λ₀×0.062λ₀.The simulation results of HFSS indicate that there is an obvious pass band around 3.86 GHz and the pass band bandwidth is 490 MHz in which the insertion loss is less than 3dB.The FSS keeps excellent performance in a wide angle range for different polarized electronic waves.更多还原
