Transmitting Antenna's Reflected Power and its Influence on Reverberation Chamber Calibration

For the reverberation chamber operating at low frequencies, the reflected power at the transmitting antenna's terminal is very large. In this paper, we analyzed the statistical property of this large reflected power. Furthermore, two different normalization methods used for chamber calibration are compared. Through measurement results, it is shown that using net power to do the normalization will give better chi-square and uniformity results than using transmission power to do the normalization. However, from the view of the practical testing, the later one greatly reduces the testing complexity and is accurate enough for the engineering application
