一种计算赋形天线增益下降的简单方法

内容简介：基站天线常采用赋形技术，以提高通信质量和减小对邻区的干扰，但采用赋形技术会导致天线的增益下降，通过方向图积分方法来计算和评估赋形天线的增益下降，计算过程复杂。介绍了一种通过分析基站天线接收信号过程中馈电网络功率合成的方法，只需几步简单的运算即可得出赋形基站天线的增益下降情况。

Abstract：Shaped beam technology for base station antenna is often used to improve communication quality and reduce the interference on adjacent area, but shaped beam technology will decline the antenna gain. The gain reduction of shaped beam antenna can be calculated through pattern integration method which is complex. A power synthetic method for feed network by analyzing the received signal on base station antenna is introduced, by which the gain reduction of shaped base station antenna can be calculated only by a few simple mathematical operations.
