摘要
讨论了PLC电磁辐射的近场测量问题,从近场耦合和相位不均2方面仿真分析了CISPR规定的鞭天线、环天线的适用性,为实际测量中天线的选用提供了依据。通过分析证明,近场时可以忽略两天线之间的近场耦合。
This paper discusses the near field measurement of PLC electromagnetic radiation, analyzes applicability of CISPR-defined whip and loop antennas by simulating from two aspects of near field coupling and phase inequality. It provides some evidences for antenna selection in practical measurement. The analysis proves that near field coupling between two antennas can be neglected.
