Abstract

In this article, the design and performance of a novel rectangular microstrip patch antenna (RMPA) utilizing the dielectric substrate material FR4 of relative permittivity (Ԑr = 4.3) and thickness (h = 0.254 mm) is proposed to operate at (fr = 28 GHz). Three different feeding techniques (microstrip inset line, coaxial probe, and proximity coupled line) are investigated to improve the antenna radiation performance especially the antenna gain and bandwidth using Computer Simulation Technology (CST) and High Frequency Structure Simulator (HFSS). The simulated frequency responses generally reveal that the proximity-coupled fed provides extremely directive pattern and maintain higher radiation performance regardless of its antenna size which is larger than the other considered feeding ones. With the presence of the three feeding techniques, the gain is improved from 5.50 dB to 6.83 dB additionally, the antenna bandwidth is improved from 0.6 GHz to 3.60 GHz at fr = 28 GHz when the reflection coefficient S11= -10 dB. Compared to the previously designed RMPA, the proposed design has the advantages of reliable size, larger bandwidth and higher gain, which make it more suitable for many 5G application systems.

5G应用中不同馈电技术矩形微带贴片天线的设计与性能分析

本文提出了一种新型矩形微带贴片天线(RMPA)的设计和性能，该天线采用相对介电常数(Ԑr = 4.3)和厚度(h = 0.254 mm)的介电衬底材料FR4，工作在(fr = 28 GHz)。利用计算机仿真技术(CST)和高频结构模拟器(HFSS)研究了三种不同馈电技术(微带插入线、同轴探头和接近耦合线)对天线辐射性能的改善，特别是天线增益和带宽的提高。模拟频率响应结果表明，无论天线尺寸如何，邻近耦合馈电都能提供极好的定向方向图，并保持较高的辐射性能。在三种馈电技术的作用下，增益从5.50 dB提高到6.83 dB，天线带宽从0.6 GHz提高到3.60 GHz，在fr = 28 GHz时，反射系数S11= -10 dB。与之前设计的RMPA相比，本文设计的RMPA具有尺寸可靠、带宽更大、增益更高的优点，更适合多种5G应用系统。
