Errors of antenna factor and improved method for NSA test

  • 摘要: 总结了归一化场地衰减(NSA,The Normalized Site Attenuation)测试中存在的误差,指出误差主要来源于天线系数.通过对天线互阻抗的分析,说明它是天线系数误差的主要来源.简单介绍了天线系数的标准计量方法,发现其中并未考虑互阻抗的影响;修正了天线系数计量中采用的方程组,证明该方程组不能求解.分析了减小测试天线间互阻抗误差的因素,重新设计了一种新的测试方法.新方法使用天线增益替代天线系数,利用天线增益测试的必要条件避免互阻抗的影响;证明了新方法与原方法的原理间的等价条件;通过实测验证了新方法的有效性.
