EMC天线的低不确定度校准(英文)

Low uncertainty calibrations of EMC antennas

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。

Electromagnetic Compatibility （EMC） emission testing of electronic equipment requires the use of accurately calibrated antennas. This paper presents several methods for antenna calibration at frequencies from 9 kHz to 18 GHz developed at the National Measurement Institute Australia （NMIA）. They include the three-antenna method for the measurements of electric antenna factors of dipole-like EMC antennas on an open area test site and above 1 GHz directional antennas in an anechoic chamber, a swept-frequency method for magnetic loop antenna calibrations and associated site validation methods.
