集成滤波器的5G大规模天线的S参数测试方法

集成滤波器的5G大规模天线由于每个通道包含了一组滤波器,使得5G大规模天线的通道之间的幅度和相位一致性指标变得很差,进一步地,使得获取除滤波器以外的纯通道之间的幅度和相位的一致性指标变得非常困难。对集成滤波器的5G大规模天线的测试方法进行了原理分析和实际测试,找到了一种具有便捷的实际应用的测试方案,通过两次测试间接获取了通道间幅度相位一致性,消除了滤波器引起的幅度相位差异。

S-parameter Test Method of 5G Massive MIMO Antenna with Integrated Filter

Since 5G massive MIMO antenna with integrated filter has a set of filters for each channel,the amplitude and phase consistency between the channels are poor,and it is difficult to further obtain the pure consistency indicators of the amplitude and phase between channels excluding the filters.This paper provides principle analysis and practical test of test method for the massive MIMO antenna with integrated filter,and finds a test solution with convenient practical application.The amplitude and phase consistency between channels are obtained indirectly through two tests,and the amplitude and phase difference caused by the filters are eliminated.
