Abstract

This study introduces a novel phase compensation-based, asymmetric frequency selective surface (FSS). Aimed at enhancing angular stability, the phase compensation method utilizes the reflected phase gradient changes generated by two FSSs at large grazing angles. The ultimate improvement in angular stability comes from unit amalgamation to achieve phase complementarity, effectively dealing with the phase shift of incident waves caused by large grazing angles. Based on this principle, the asymmetric FSS structure is built with 3 components: a Minkowski fractal cell, a bent-line square-loop cell, and a thin square-loop parasitic cell. Simulation results show the structure demonstrates a 0 relative shift of resonant frequency within an incidence range of 0-80° under transverse electric (TE) polarization. However, it exhibits a maximum relative shift of 5.12% in resonant frequency at an 80° incidence under transverse magnetic (TM) polarization. Compared with E 1 and E 2 units, this structure significantly reduces frequency deviation—by 100% at 80° incidence under TE polarization and by 80.12% and 83.26% compared with E 1 and E 2 units under TM polarization. Finally, the proposed FSS model was fabricated and processed, with measured data basically aligning with the simulated results.

利用相位补偿法增强频率选择性表面设计的角度稳定性

本研究介绍了一种基于相位补偿的新型非对称频率选择表面（FSS）。为了增强角度稳定性，相位补偿方法利用了两个 FSS 在大掠角下产生的反射相位梯度变化。角度稳定性的最终改善来自于通过单元合并来实现相位互补，从而有效地处理大掠射角引起的入射波相移。根据这一原理，非对称 FSS 结构由三个部分组成：闵科夫斯基分形单元、弯曲线方环单元和薄方环寄生单元。仿真结果表明，在横向电（TE）极化条件下，该结构在 0-80° 入射角范围内的谐振频率相对偏移为 0。然而，在横向磁（TM）极化条件下，其谐振频率在 80° 入射角范围内的最大相对偏移为 5.12%。与 E 1 和 E 2 单元相比，该结构大大减少了频率偏差，在 TE 极化条件下，入射角为 80°时，频率偏差减少了 100%；在 TM 极化条件下，与 E 1 和 E 2 单元相比，频率偏差分别减少了 80.12% 和 83.26%。最后，对提出的 FSS 模型进行了制作和处理，测量数据与模拟结果基本一致。
