N2 - The reverberation chamber (RC) has been widely applied to antenna measurements. With decades of researches, RC has been proven to be an efficient and effective means to determine antenna efficiencies. Various methods have been proposed for accurate estimation of the antenna efficiency. However, all of them determine antenna efficiency through a single measurement. In this paper, we proposed moment estimator (ME) and maximum likelihood estimator (MLE) for two non-reference antenna methods (i.e., one-and three-antenna methods), utilizing several sets of measurements. Both simulations and measurements are conducted to verify the proposed models. It is shown that ME and MLE provide more stable and accurate estimations compared with a single measurement. ME and MLE can also cope with unpredictable and indeterminate overestimations and underestimations due to finite samples of the random process.
