Effects of the Correction for Impedance Mismatch on the Measurement Uncertainty in a Reverberation Chamber

摘要

The impedance mismatches of the antennas, that are used for the measurements of the transmission and reflection coefficients in a reverberation chamber, affect the estimate of the relevant coefficients, according to the importance of the mismatches. Therefore, a correction for impedance mismatch is in general necessary. Besides the mean, such a correction affects the standard deviation and the variation coefficient of the sample distribution of the measured coefficients. By a statistical analysis, the estimate of these impacts is shown.
