A Comparison of Antenna Efficiency Measurements Performed in Two Reverberation Chambers Using Non-reference Antenna Methods

摘要

In this paper, we inter-compare the antenna efficiency obtained from two different reverberation chambers using non-reference antenna methods in order to assess the chamber effects on the methods. A directional antenna and an omni-directional antenna are used for this study. It is found that the difference between the results is relatively small with a maximum up to around 10% within their operational frequency bands. These results demonstrate that the non-reference antenna measurement technique, especially the two-antenna method, is robust.
