摘　　要：本文设计了一种工作于5G毫米波频段的低副瓣高增益平面阵列天线。该天线结构由128个天线阵元组成,采用泰勒分布综合法构建阵列天线的非等幅馈电网络,从而降低阵列天线副瓣幅度,提升天线阵列的辐射效率。经过仿真验证,阵列天线阻抗带宽达到3.95 GHz,工作频段内天线最高增益为19.10 dBi,E面主副瓣电平比低于﹣20 dB,符合设计要求。通过优化馈电网络的设计,成功实现了低副瓣高增益的目标。同时,还对天线的性能进行了全面的仿真和验证。结果表明,在5G毫米波频段内,该天线具有较宽的阻抗带宽和较高的增益;天线的副瓣电平较低,可以有效降低干扰和提高信号的质量。在未来的5G通信系统中,该天线可用于增强覆盖范围、提高通信质量和容量。由于其适用于毫米波频段,还可以应用于雷达系统、无线传感器网络等领域。因此,本研究对于5G通信技术的发展以及相关领域的应用具有一定的推动作用。This article designs a low sidelobe high gain planar array antenna operating in the 5G millimeter wave frequency band.The antenna structure consists of 128 antenna elements,and a non-uniform feed network of the array antenna is constructed using the Taylor distribution synthesis method,thereby reducing the sidelobe amplitude of the array antenna and improving the radiation efficiency of the antenna array.After simulation verification,the impedance bandwidth of the array antenna reaches 3.95 GHz,and the maximum gain of the antenna in the operating frequency band is 19.10 dBi.The E-plane main and side lobe level ratio is less than-20 dB,which meets the design requirements.By optimizing the design of the feed network,this article successfully achieved the goal of low sidelobe and high gain.At the same time,this article also conducted a comprehensive simulation and verification of the performance of the antenna.The results show that the antenna has a wide impedance bandwidth and high gain in the 5G millimeter wave frequency band;The sidelobe level of the antenna is relatively low,which can effectively reduce interference and improve signal quality.In future 5G communication systems,this antenna can be used to enhance coverage,and improve communication quality and capacity.Due to its applicability in the millimeter wave frequency band,it can also be applied in fields such as radar systems and wireless sensor networks.Therefore,this study has a certain promoting effect on the development of 5G communication technology and its application in related fields.
