摘要

本文提出了一种新的稳定的频率选择曲面。提出的设计包含单面FR-4衬底，具有一个方形和两个交叉形状的环路，可实现三频段抑制(1.8 GHz, 2.5 GHz和3.5 GHz)特性。FR-4衬底的介电常数为4.4，损耗正切为0.02，尺寸为0.12 λ × 0.12 λ。由于结构对称，投影FSS设计与偏振无关。因此，在垂直的TE和平行的TM波模式下，它都产生了稳定的法向和斜入射角谐振频率响应。仿真结果验证了所设计的FSS的稳定性，并在CST微波工作室中基于FDTD方法的频域求解器中实现。分析了在1.8 GHz、2.5 GHz和3.5 GHz带阻/陷波频率下的传输和反射特性。更重要的是，所提出的FSS非常适合于移动和无线室内应用中的电磁屏蔽，覆盖广泛的频谱，具有更广泛的就业能力。

A novel polarization independent triple bandstop frequency selective surface for the mobile and wireless communication

In this paper, a novel and stable frequency selective surface has been proposed. The proposed design has incorporated a single sided FR-4 substrate with one square and two-crossed shaped loops which led to triple band reject (1.8 GHz, 2.5 GHz and 3.5 GHz) characteristics. The FR-4 substrate has a dielectric constant of 4.4 with loss tangent of 0.02 and dimension of 0.12 λ × 0.12 λ. The projected FSS design is polarization independent due to symmetrical structure. Therefore, it has produced a stable resonant frequency response at normal and oblique angles of incidences for both perpendicular TE and parallel TM wave modes. This stability of designed FSS has verified by its simulated results and realized in CST Microwave studio in frequency domain solver based on FDTD method. The transmission and reflection characteristics have analyzed at the selected band-stop/notch frequencies 1.8 GHz, 2.5 GHz and 3.5 GHz. More importantly, the proposed FSS is well suited to electromagnetic shielding in mobile and wireless indoor applications covering a wide spectrum with wider employability.
