摘　　要：5G平面波模拟器是一种新型的空口测量系统,通过对系统中阵列天线各个天线单元进行合理的幅度相位激励,在近场距离合成准平面波。在准平面波环境中既可以进行传统的无源天线指标测量,又可以进行基站射频指标和系统性能指标测量。平面波模拟器系统能够有效压缩测量空间,从而大大节省测量系统成本,是空口测量取代传统传导测量的一种重要技术方案。从5G平面波模拟器的发展历程、设计方法及应用等几个方面进行了论述。The plane wave generator(PWG)is a novel measurement system for 5G over the air(OTA)testing.A quasi plane wave in the near-filed is synthesized by exciting the antenna elements in the PWG array gracefully.The PWG system does not only meet the requirements of traditional passive antenna measurement,the radio frequency(RF)parameters as well as system performance of the base station(BS)can be accurately measured in the same system.The application superiority of the PWG system is the spacing saving ability,resulting in a significant cost saving,which prompt it to become an alternative solution of the traditional conducted measurement technology.In this paper,the developing history,the design process and typical scenarios in 5G application of the PWG system are proposed.
