摘　　要：高铁5G网络覆盖面临车体穿越损耗大、多普勒频移、业务切换频繁和基站间距大等诸多问题。透镜天线具有高增益、垂直波瓣宽、损耗小和天线效率高的特点。为有效解决高铁覆盖面临的问题,本文通过在高铁5G覆盖中试点应用透镜天线与普通板状天线,分析得出相同覆盖距离透镜天线覆盖更优,相同覆盖效果透镜天线覆盖更远,透镜天线相较板状天线可显著提升5G网络覆盖性能。The coverage of high-speed rail 5G network faces many problems such as high vehicle traversal loss,Doppler frequency shift,frequent business switching,and large base station spacing.To solve these problems,this article piloted the application of lens antennas in high-speed rail 5G coverage.With its advantages of high gain,vertical lobe width,low loss,and high antenna efficiency,it can significantly improve the coverage performance of 5G network compared to ordinary plate antennas.Lens antennas with the same coverage distance have better coverage,Lens antennas with the same coverage eff ect cover farther.
