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.
