摘要

本文研究了CISPR 25夹具“长线天线”产生的电场分布，该夹具被放置在半消声室的地板上，或放置在高架地平面上，如在1米距离测试中使用杆天线。通过对电场分布的分析，提出了棒状天线布置和电气操作两种方案。这两种选择目前没有被标准考虑，但可以产生无共振响应和测量电平，与当前的标准测试设置兼容。实验结果证实了预测，并在半消声和全消声设备中获得。

Resonance free operation of the rod antenna for 1 m distance testing up to 30 MHz

The electric field distribution generated by the CISPR 25 fixture named “long wire antenna” is here investigated both in the case where the fixture is placed on the floor of a semi-anechoic chamber or on an elevated ground plane as in 1 m distance testing with rod antenna. The analysis of the electric field distribution suggests two options for rod antenna placement and electrical operation. These two options are not presently considered by the standards but can produce resonance free response and measured levels compatible with current standard test setups. Experimental results are offered that confirm predictions and that are obtained in both semianechoic and fully-anechoic facilities.
