摘　　要：提出并设计了一种工作在5G N41频段的高隔离度皮基站4×4 MIMO全向天线系统,该天线系统由1 mm厚度的铝基板、4个平面倒F天线单元和2个L形隔离单元组成,天线整体结构尺寸为180 mm×180 mm×10 mm。仿真研究表明,该4×4 MIMO天线阵列的4个单元天线,在主要工作频带内输入端回波损耗均小于-10 dB,单元天线之间的隔离度均大于25 dB,单元天线在水平面的增益大于1 dBi。该4×4 MIMO全向天线具有低剖面、高隔离度、结构简单易于加工集成等特点,具有良好的应用前景。In this paper,a high isolation omnidirectional 4×4 MIMO antenna system operating in 5G N41 is presented and designed.The antenna system is composed of an aluminum substrate,four planar inverted F antennas,and two L-shaped isolation units.The size of the antenna system is 180 mm×180 mm×10 mm.The numerical simulation results show that the planar inverted F antenna has an input return loss less than-10 dB,the isolation between two antenna ports is more than 25 dB,and the antenna gain reaches 1 dBi.The omnidirectional 4×4 MIMO antenna system has the characteristics of low profile,high isolation and easy processing and integration,which has a better application prospect.
