移动通信基站天线互调的参数化分析方法

摘要

针对当前基站天线设计生产厂家的互调经验分析方法，提出了基站天线互调的参数化分析方法。通过引入能量和相位的概念，介绍了基站天线互调设计原则，研究了基站天线互调生产参数化管控手段，分析了基站天线互调返修中的参数化故障定位方法，并通过实验证实了在3个环节之间建立有效的参数化反馈机制可以实现参数化分析基站天线互调。%According to analysis method on passive intermodulation (PIM) of base station (BS) antenna’ manufacturer at present, a parametric analysis method on PIM of BS antenna was proposed. The concepts of energy and phase were introduced and design principle of BS antenna PIM was described. Parametric control means of BS antenna PIM production was studied and parametric default location method of BS antenna PIM in repair was analyzed. It is veriifed through experiment that the establishment of effective parametric feedback mechanism between three links can achieve parametric analysis on PIM of BS antenna.
