Extension of site attenuation for radiated emission test site evaluation above 1 GHz
We developed a conical dipole antenna that operates in the frequency range of 1 GHz to 6 GHz as a broadband antenna. In this paper we describe site attenuation measurements in the 1 GHz to 6 GHz frequency range using this antenna for the CSA (Classical/Conventional Site Attenuation) and NSA (Normalized Site Attenuation) methods, and we verified that measuring site attenuation using this conical dipole antenna is an appropriate method for evaluating radiated emission test sites above 1 GHz. Site attenuation is more sensitive for detecting unwanted reflection waves than Site VSWR. Therefore site attenuation is superior to Site VSWR for use in site validity evaluation. Site attenuation in the 30 MHz to 1000 MHz range has been the standard method with logical underpinnings used for more than 20 years and is recognized by CISPR and many countries as the national standard. The method proposed above permits the same method of evaluation of the suitability of radiated emission test sites to be extended to the 1 GHz to 6 GHz frequency range; coherence and continuity are maintained, which we believe to be highly significant.
