Abstract

An ultra-wideband reject, polarization-insensitive patch-type frequency-selective surface (FSS) with great angular stability is designed, and results are well demonstrated. The proposed FSS is fabricated on single-layer FR4 substrate with a compact size of \(0.083\lambda_0 \times 0.083\lambda_0 \times 0.013\lambda_0\). The proposed FSS covered the complete ultra-wide frequency band of 2.5–16.24 GHz. The covered \(< -10\,{\text{dB}}\) and \(< -20\,{\text{dB}}\) fraction bandwidths are 146.63% and 76.67%. The proposed FSS is polarization-insensitive and offers angular stability up to 80°. The measured results are compared with the reported ultra-wideband FSSs in the literature to establish the novelty of this work.

用于电磁屏蔽的偏振不敏感大扫描角宽带阻挡频率选择表面

设计了一种具有极高角度稳定性的超宽带剔除、偏振不敏感贴片型频率选择表面（FSS），并对结果进行了很好的演示。所提出的 FSS 是在单层 FR4 衬底上制作的，尺寸小巧（0.083\lambda_0 \times 0.083\lambda_0 \times 0.013\lambda_0\）。拟议的 FSS 覆盖了 2.5-16.24 GHz 的整个超宽频段。覆盖的（< -10,{text{dB}}）和（< -20,{text{dB}}）分数带宽分别为146.63%和76.67%。所提出的 FSS 对偏振不敏感，并且具有高达 80° 的角度稳定性。测量结果与文献中报道的超宽带 FSS 进行了比较，从而确定了这项工作的新颖性。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
