摘 要：文章通过对电磁波理论和不同类型天线方向图进行对比分析，结合移动通信网中的实测数据，相互验证，形成了基站天线俯仰角预规划算法，经过分析调整的简易算法可以较好地完成移动通信网络规划初期大规模基站天线俯仰角的初步设定，避免了直接继承现网工程参数与新天线不匹配的问题，可以为覆盖仿真工具提供初步的俯仰角设定值，降低天线调整工作量，也可以为现场勘察人员提供较为准确的参考值，以达到快速、精确完成规划设计的目的。

Abstract：In this paper，through the comparative analysis of electromagnetic wave theory and different types of antenna pattern，combined with the measured data in the mobile communication network，mutual verification，a simple algorithm of base station antenna pitch angle pre-planning is formed. The simple algorithm after analysis and adjustment can better complete the initial setting of the pitch angle of the large-scale base station antenna in the initial stage of mobile communication network planning，avoid the problem of directly inheriting the existing network engineering parameters and mismatching the new antenna，and can provide the preliminary pitch angle setting value for the coverage simulation tool，reduce the workload of antenna adjustment，and also provide more accurate for the field investigators Reference value，in order to achieve rapid and accurate completion of planning and design purposes.
