本文介绍了适用于 5G mmWave（毫米波）应用的薄型双负 (DNG) 超材料单元结构的设计和分析。该结构由双槽矩形环贴片组成，在磁共振附近经历峰值电流值，导致超材料在 28 GHz 下谐振，在该频率下表现出负的有效介电常数和磁导率。 3.05 mm x 2.85 mm 紧凑结构设计在 Rogers RT/Duroid 5880 基板上，可在 5G 频率范围 (27.1-29.2 GHz) 内实现更好的有效介质比 (EMR)。进行严格的参数研究以获得拟议的设计。全波电磁仿真软件工具 CST 和 HFSS 用于生成用于分析的散射参数。采用Nicolson-Ross-Wier方法来观测负有效介电常数和磁导率。此外，还研究了不同的输出量，例如表面电流以及电场和磁场分布。该结构还使用 1 x 2、2 x 2 和 4 x 4 阵列进行了进一步测试，结果显示与 5G 毫米波应用的考虑程度足够一致。
This article presents the design and analysis of a low profile double-negative (DNG) metamaterial unit structure for 5G mmWave (millimeter wave) applications. The structure, comprised of double-slotted rectangular ring patches, experiences the peak current value near the magnetic resonance, causing the metamaterial to resonate at 28 GHz where it exhibits negative effective permittivity and permeability. The 3.05 mm x 2.85 mm compact structure is designed over a substrate Rogers RT/Duroid 5880 to attain better effective medium ratio (EMR) in the 5G frequency range (27.1-29.2 GHz). A rigorous parametric study is conducted to obtain the proposed design. Full-wave electromagnetic simulation software tools CST and HFSS are used to generate the scattering parameters for the analysis. The Nicolson-Ross-Wier method is used to observe the negative effective permittivity and permeability. In addition, different output quantities, e.g., surface current and electric and magnetic field distribution, are investigated. The structure is further tested with 1 x 2, 2 x 2, and 4 x 4 arrays, where the results show adequate agreement to be considered for 5G mmWave applications.
