Abstract

While we are moving towards a digitized era where everything is getting digital, then the transmission of the signal at the desired frequency range becomes a matter of apprehension. Signal transmission has affected by various propagation effects, path loss, interference etc. As is well acknowledged that Frequency selective surface is a filter which has a stable frequency response even though the electromagnetic waves to surface are fluctuated. A Bandpass FSS is proposed in this paper that has stable frequency response as the proposed structure symmetrical and insensitive towards polarization. The proposed structure contains a single sided FR4 substrate with dielectric constant 4.4mm, thickness 1.6mm tangential loss 0.025 and the dimension of the unit cell is 0.24 λ × 0.24λ. The structure consists of a square and two octagons that provide stable frequency response at 2.4GHz, 3.5GHz, and 5.5GHz. The simulated results shows good insertion loss in both TM and TE wave modes at various angles of incidence. Simulation is carried out in CST microwave studio that is based on FDTD method in frequency domain solver.

一种用于增强WiMax和WLAN传输应用的三带通频率选择表面

当我们走向数字化时代，一切都变得数字化，那么在期望的频率范围内传输信号就成了一个棘手的问题。信号的传输受到各种传播效应、路径损耗、干扰等因素的影响。众所周知，频率选择表面是一种滤波器，即使到达表面的电磁波是波动的，它也具有稳定的频率响应。本文提出了一种具有稳定频率响应的带通FSS，其结构对称且对极化不敏感。该结构包含单面FR4衬底，介电常数为4.4mm，厚度为1.6mm，切向损耗为0.025，单元胞尺寸为0.24λ × 0.24λ。该结构由一个方形和两个八边形组成，在2.4GHz、3.5GHz和5.5GHz下提供稳定的频率响应。仿真结果表明，在不同入射角下，TM波和TE波都具有良好的插入损耗。在基于频域求解器FDTD方法的CST微波工作室中进行了仿真。
