Abstract

This paper presents a wide band novel-shaped microstrip antenna with a parasitic element for 5G wireless application. The Rogers RT 5880 substrate (2.2, 0.0009) having a compact size of $32.5\times 25.25mm^{2}$ and a height of 1.575 millimetres is selected for the 5G antenna design. The results of the designed antenna show a reflection coefficient of -38.15dB, a gain of 2.43 dB and directivity of 3.63 dBi at 4.22 GHz. It also shows that the average radiation efficiency of the antenna is 76.2% over the 1.56 GHz large operating band. Moreover, it is found from the simulation results that the voltage standing wave ratio is 1.02 at 4.22 GHz. All the parameters used in designing the antenna help to achieve a large operating bandwidth of 1.56 GHz, which ranges from 3.33 GHz to 4.89 GHz. The antenna described in this paper can be a good contestant for WLAN as well as 5G communications because of its Omni-directional stable radiation pattern, acceptable efficiency and gain with a compact volume.

一种面向5G通信的带寄生元件的全向新型贴片天线

针对5G无线应用，提出了一种带寄生元件的宽带新型微带天线。5G天线设计选用Rogers RT 5880基板(2.2,0.0009)，其紧凑尺寸为32.5\ × 25.25mm^{2}$，高度为1.575毫米。结果表明，该天线在4.22 GHz时的反射系数为-38.15dB，增益为2.43 dB，指向性为3.63 dBi。结果表明，该天线在1.56 GHz大工作频段的平均辐射效率为76.2%。仿真结果表明，在4.22 GHz时，电压驻波比为1.02。设计天线时使用的所有参数都有助于实现1.56 GHz的大工作带宽，范围从3.33 GHz到4.89 GHz。该天线具有全向稳定的辐射方向图、可接受的效率和增益以及小巧的体积，可以成为WLAN和5G通信的良好竞争者。
