大功率对数周期天线电气参数变化原因分析

Analysis of Causes of Change in Electrical Parameters of High Power Log Periodic Antenna

本文介绍了对数周期天线工作原理以及对数周期天线在大功率短波广播发射使用时,因阻抗不匹配造成电气参数的变化。通过对天线进行测试并对数据进行分析,查找原因,分析问题,拟定改造计划。

This paper introduces operating principle of log periodic antenna and its electrical parameters change caused by impedance mismatch during high power SW radio transmitting. Through testing the antenna and analyzing data, we i nd out the reasons, analyze the question, and put out a reform plan.
