在本文中，低剖面小型化元件频率选择表面（FSS）的数值模拟以及实验。所提出的设计由印刷在超薄（0.0005λ0）FR-4基板的两侧上的曲折图案组成，该基板在750 MHz下具有0.017λ0 × 0.017λ0的单元尺寸的带通特性。该结构本质上是非对称的，选择性地实现特定偏振的带通操作，而透射其他偏振的入射波。与早期报道的结构相比，该设计的新颖性在于其小型化性能以及超薄外形。通过推导等效电路模型和参数变化，进一步分析了所提出的结构。最后，制作了一个频率选择表面的原型，在垂直入射下的测量响应与模拟结果吻合较好。
In this paper, a low‐profile miniaturized‐element frequency selective surface (FSS) is presented numerically as well as experimentally. The proposed design consists of a meandered pattern printed on both sides of an ultra‐thin (0.0005λ0) FR‐4 substrate, which exhibits a bandpass characteristic at 750 MHz having unit cell dimensions of 0.017λ0 × 0.017λ0. The structure, being asymmetric in nature, selectively realizes bandpass operation for a specific polarization, whereas transmits incident wave for other polarizations. The novelties of the design lie in its miniaturization performance as well as ultra‐thin profile as compared with the earlier reported structures. The proposed structure has further been analyzed through deriving equivalent circuit models and parametric variations. Finally, a prototype of the FSS is fabricated and the measured response is in good agreement with the simulated result under normal incidence.
