Abstract

This paper addresses a few specific aspects of measuring the lower bound of antenna efficiency in a reverberation chamber. While the initial method for measuring the lower bound of efficiency has been presented, three key revisions are discussed here: (1) an updated notation, (2) a revised method for calculating the lower bound of efficiency, and (3) a new method for combining stirring techniques. The updated antenna model notation is designed to be more general and applicable to situations with n antennas. The revised efficiency calculation targets an issue of the original method where the minimum bounding circle exceeded the unit circle. Introducing a new method of combining stirring techniques addresses a weakness of the original model. For the model to work well, it needs a very large number of paddle positions that generate a good statistical approximation of the environment (in this case, a reverberation chamber). As a possible remedy to this weakness, we propose a different way of combining stirring techniques.
