Abstract :
Reverberation chambers (RC) are becoming a popular alternative testing facility for a wide range of electromagnetic applications. In particular, these chambers are ideally suited for performing radiated power measurements of either an antenna or a device under test, and as such, it is possible to estimate the efficiency of antennas. In previous work we presented a two-antenna approach that allows for estimating the efficiency of two antennas under test without the need for a reference antenna, nor the need to assume that both antennas are identical. In this paper, we validate this two-antenna approach by showing comparisons with other methods (i.e., comparing measurements made in different test facilities and comparisons to other techniques, including numerical calculations) for various antennas.
