Abstract

In this paper, a defected ground-structured antenna with a stub-slot configuration is proposed for future 5G wireless applications. A simple stub-slot configuration is used in the patch antenna to get the dual band frequency response in the 5G mid-band and the upper unlicensed frequency region. Further, a 2-D double period Electronic band gap (EBG) structure has been implemented as a defect in the metallic ground plane to get a wider impedance bandwidth. The size of the slots and their positions are optimized to get a considerably high impedance bandwidth of 12.49% and 4.49% at a passband frequency of 3.532 GHz and 6.835 GHz, respectively. The simulated and measured realized gain and reflection coefficients are in good agreement for both operating bandwidths. The overall antenna structure size is 33.5 mm × 33.5 mm. The antenna is fabricated and compared with experimental results. The proposed antenna shows a stable radiation pattern and high realized gain with wide impedance bandwidth using the EBG structure, which are necessary for the requirements of IoT applications offered by 5G technology.

摘要

本文提出了一种具有短截线-缝隙结构的缺陷接地结构天线，用于未来的5G无线应用。在贴片天线中采用简单的短截线-缝隙结构，以在5G中频段和上部非授权频段获得双频段频率响应。此外，二维双周期电子带隙（EBG）结构被实现为金属接地平面中的缺陷，以获得更宽的阻抗带宽。对缝隙的尺寸及其位置进行了优化，在3.532 GHz和6.835 GHz的通带频率下分别获得了相当高的12.49%和4.49%的阻抗带宽。在两个工作带宽内，模拟和测量的实现增益与反射系数都吻合良好。天线的整体结构尺寸为33.5 mm×33.5 mm。制作了该天线并与实验结果进行比较。所提出的天线利用EBG结构展现出稳定的辐射方向图和高实现增益以及宽阻抗带宽，这对于5G技术提供的物联网应用需求而言是必要的。
