采用通信基站轴向功率衰减公式与均匀直线天线阵模型，对联通WCDM A基站产生的电磁辐射在轴向、水平及垂直方向上进行了系统计算与预测。结果表明：通信基站电磁辐射主要集中在其轴向区域，当距离超过19m时，功率密度衰减至限值标准以下。当距离天线垂直距离小于3m时，电磁辐射在水平方向上的分布有超标空间，大于4m时，已经没有超标空间。WCDM A 基站的水平、垂直防护距离可分别定为19m ，4m。现场实测结果与理论预测符合性较好，表明采用的预测公式与模型具有较好的应用性。

Adopting axial power attenuation formula and uniform linear array model of communication base station , this article calculates and predicts the ER distribution in the axial ,vertical and horizontal direction of WCDM A base station .Results suggest that the ER is mainly focused on the axial area and when the distance is more than 19m ,the power density decreases to below the limitation standard .When the vertical distance is less than 3m ,there are some spaces exceeding the standard .But when the distance is more than 4 m in vertical ,there is no excessive space . Therefore ,the horizontal and vertical protection distance of WCDMA base can be set as 19m and 4m respectively . The practical monitoring results and simulation results fit well with the suggested in this article ,which indicates that the formula and model have better applicability .
