摘　　要：详细分析了天线增益下降、旁瓣信号泄露、前后比不达标、覆盖异常等常见的天线问题,通过研究信号传播理论以及小区覆盖模型,提出了一种基于天线水平波瓣区间化成形分析的故障天线定位算法,把天线水平辐射波瓣按照不同方向角度区间进行划分,分别是±[0,15°]、[16°,30°]、[31°,60°]、[61°,90°]、[91°,120°]、[121°,150°]、[151°,180°]共7个区间,通过不同区间的路测数据(如Rxqual、Rxlev Average、过覆盖指数、绝对通信距离)进行多维度关联分析,定位故障以及天线覆盖异常点。The problems such as decrease of antenna gain,the leakage of side-lobe signal,and the degradation of front-to-back ratio,were mainly discussed,and an algorithm of faulty antenna location based on interval analysis of horizontal beam-width was proposed,by dividing the horizontal beam-width with different radiation angle：±[0,15°],[16°,30°],[31 °,60°],[61 °,90°],[91 °,120°],[121 °,150°],[151 °,180°].At last,through relational analysis of Rxqual,Rxlev,over-coverage index,and communication distance in different radiation angle interval,the location of faulty antenna was realized.
