在进行电子设备的电磁兼容辐射骚扰测量时,所用天线的精确校准是必不可少的。给出几种9 kHz到18 GHz的天线校准方法。这些方法主要包括以三天线法为基础的自由空间天线系数的测量方法及相关场地检测法。天线包括偶极子天线和相似天线及1 GHz以上的方向性天线。场地包括开阔场地和全电波暗室。天线校准方法也包括一个环形天线的磁天线系数校准的扫频方法及相关场地检测法。
Precise calibration of the antennas used is essential when making EMC measurements of electronic equipment. Several methods of antenna calibration from 9 kHz to 18 GHz are given. These methods mainly include the measurement method of free space antenna coefficient based on the three-antenna method and the related field detection method. Antennas include dipole antennas and similar antennas and directional antennas above 1 GHz. Venues include open space and anechoic chamber. The antenna calibration method also includes a frequency sweep method of magnetic antenna calibration of the loop antenna and associated field detection method.
