| 摘 要： | 天线系数在EMC 测试中是一项重要参数。然而天线生产者提供的天线系数都是在一定前提下进行校准的,
如果直接使用会带来测量误差。所以必须进行校准。本文介绍几种常用的校准方法，详细阐述了如何用三天线法测量
校准天线系数，并对影响测量结果因素进行分析，给出改进方法。

| Abstract: | the antenna coefficient is the important parameter in EMI test. The antenna coefficient must be calibrated
because the antenna coefficient, provided by the antenna manufacturer, is calibrated under certain conditions and it will cause
the measurement error if the antenna coefficient is used directly. Several common calibration methods are introduced in this
paper, and the tri-antenna method used for measure and calibrate the antenna coefficient are illustrated in details, and the
improvement is put forward after the analysis of the factors which will affect the result. |
