| Abstract(in English) | Our previous second paper proposed a newly developed conical dipole antenna that operates in the frequency range of 1 to 6GHz and provides a separation of more than 25dB between vertically and horizontally polarized waves. We have shown that when using this antenna at an EMI measurement site being evaluated and moreover the measured attenuation of the vertically and horizontally polarized waves are identical, free space characteristics of the site are verified. In this paper we describe site attenuation measurement in the 1 - 6MHz frequency range using this antenna for the CSA (Conventional Site Attenuation)/NSA (Normalized Site Attenuation) methods, and we verified that measuring site attenuation using this conical dipole antenna is an appropriate method for evaluating EMI sites. Moreover, evaluation of EMI sites by their attenuation in the 30 to 1000MHz range has been the standard method with logical underpinnings used for more than 20 years and recognized by CISPR and many countries as the national standard. The method proposed above permits the same method of evaluation of suitability of EMI sites to be extended to the 1 - 6GHz frequency range, coherence and continuity are maintained, which we believe to be highly significant. |
