Abstract

This manuscript presents the design and simulation of a wideband antenna for millimetre-wave (mmWave) 5G wireless communication. The antenna is designed using Rogers RT5880 substrate of thickness 0.254 mm and with dielectric constant 2.2 to cover the 5G FR-II New Radio (NR) bands n257, n258, and n261. Initially, a narrowband antenna is designed by using mathematical equations and then the structure is modified by incorporating a partial ground plane (PGP) with a slot and inserting a circular tapered slot in the patch to achieve a wide bandwidth. The optimization is performed by using CST Microwave Studio and Ansys HFSS software, and the results are validated. The proposed antenna depicts an effective impedance bandwidth of 17.13 GHz, ranging from 19.5 GHz to 36.63 GHz with a fractional bandwidth of 61%. The characteristics achieved are adequate such as the value of the VSWR and the minimum to maximum radiation efficiency ranges from 96% to 99%. This research provides a promising solution for a wideband antenna designed for mmWave 5G wireless communication.

超薄宽带印刷天线FR-II NR n257, n258和n261，用于5G无线应用

本文介绍了用于毫米波(mmWave) 5G无线通信的宽带天线的设计和仿真。该天线采用厚度0.254 mm、介电常数2.2的Rogers RT5880基片设计，覆盖5G FR-II新无线电(NR) n257、n258和n261频段。首先利用数学方程设计窄带天线，然后对天线结构进行改进，将带插槽的部分地平面(PGP)加入到贴片中，并在贴片中插入一个圆形的锥形插槽，从而获得更宽的带宽。利用CST Microwave Studio和Ansys HFSS软件对优化结果进行了验证。该天线的有效阻抗带宽为17.13 GHz，范围为19.5 GHz至36.63 GHz，分数带宽为61%。所获得的特性是足够的，例如VSWR值和最小至最大辐射效率范围为96%至99%。该研究为毫米波5G无线通信的宽带天线设计提供了一个有前途的解决方案。
