基站天线室内测量系统的误差分析

内容简介：分析了基站天线室内测量系统的误差源,理论证明微波暗室是影响测量结果(电压驻波比,隔离度)的重要因素.根据对测试结果的分析,得出了关于微波暗室对天线性能参数影响的几点结论.最后指出了所用方法的不足之处,提出了新的分析方法.

Abstract：This paper analyzes the potential error sources in the indoor test system for base station antenna and proves theoretically that the absorber chamber has an important influence on the measuring results (Voltage Standing Wave Ratio - VSWR, Isolation). According to the data analyses on the measuring results of different antennas in different absorber chambers, some conclusions are drawn on influences from absorber chambers. Finally, a new analysis method is proposed.
