摘要
导出了用天线方向图的半功率波束宽度快速计算口径天线方向性系数和增益的简单表达式 ,分析讨论了这些公式的应用范围。最后 ,给出了卫星通信天线的增益测量实例 ,实验结果表明 :用半功率波束宽度快速计算的天线增益与其它方法测量的天线增益吻合很好 。
The simple formulae of fast calculating aperture antenna directivity and gain are derived using antenna beamwidths. Applied range of these formulae are analyzed and discussed. At last, examples of measuring gain of satellite communication antennas are given. Experimental results show that the fast calculated antenna gains using beamwidths agree well with the measured antenna gain using other methods, and the correctness of this method is verified.
