Abstract

New reflector structure (RS) based on ultra-wide stopband single-layer frequency selective structure (FSS) for mid-band sub-6 GHz 5G applications is designed. The proposed RS is arranged into array of 7 × 7-unit cell of FSS elements for antenna gain and front-to-back ratio enhancement. The single antenna element of volume 30 × 20 × 1.6 (in mm3) consists of a dual-quarter-circular truncated edge-fed rectangular slot (R-slot) loaded rectangular patch (R-patch) antenna with degraded ground structure (DGS) to operate at 3.6 GHz mid-band sub-6 GHz 5G and 5.8 GHz WBAN band. The proposed unit cell FSS element, the RS of volume 55.5 × 55.5 × 13.2 (in mm3) and the associated antenna are designed on lossy thin FR-4 substrate material and investigated numerically using commercial computer simulation technology microwave studio (CST-MS) software. The studied dual-structure based RS made with array of single-layer FSS and monopole R-patch antenna is fabricated and measured. The measured impedance bandwidth (IBW) of 48.28% (3.06–4.85 GHz) and 86.20% (5–10 GHz), peak gain of 5.36 and 7.45 dBi, radiation efficiency of 67.11% and 80.16%, and front-to-back ratio of 12.23 dB and 22.84 dB are achieved at the resonant frequencies 3.5 and 5.8 GHz respectively. The FSS reflector associated with the dual-band monopole R-patch antenna performances are in good agreement with the portable wireless applications requirements.

使用单层阻带 FSS 反射器增强增益的双频双截 R 槽加载单极子贴片天线

本文设计了基于超宽阻带单层频率选择结构（FSS）的新型反射器结构（RS），适用于中频段 6 GHz 以下的 5G 应用。拟议的反射器结构由 7 × 7 单元的 FSS 元件组成阵列，用于增强天线增益和前后比。单个天线元件的体积为 30 × 20 × 1.6（单位：mm3），由双四分圆截边馈电矩形槽（R-slot）加载矩形贴片（R-patch）天线和降级接地结构（DGS）组成，可在 3.6 GHz 中频段 sub-6 GHz 5G 和 5.8 GHz WBAN 频段工作。所提出的单元单元 FSS 元件、体积为 55.5 × 55.5 × 13.2（mm3）的 RS 以及相关天线是在有损耗的 FR-4 薄基板材料上设计的，并使用商用计算机仿真技术微波工作室（CST-MS）软件进行了数值研究。所研究的基于双结构的 RS 由单层 FSS 阵列和单极 R-patch 天线组成，并进行了制作和测量。在谐振频率 3.5 和 5.8 GHz 时，测量阻抗带宽（IBW）分别为 48.28%（3.06-4.85 GHz）和 86.20%（5-10 GHz），峰值增益分别为 5.36 和 7.45 dBi，辐射效率分别为 67.11% 和 80.16%，前后比分别为 12.23 dB 和 22.84 dB。与双频单极子 R-patch 天线相关的 FSS 反射器的性能与便携式无线应用的要求十分吻合。
