Fast Evaluation of the Antenna Efficiency by a Determined Reverberation Chamber

Recently, reverberation chambers (RCs) have become a hotly discussed research area in electromagnetic compatibility (EMC). Researchers focus on the theoretical or physical explanations and their applications. As a concise method, RC provides another method to determine the efficiency of an antenna using a known chamber. The method is introduced in detail in this paper, including deducing the computational process and finding independent frequency points. Combining the obtained quality factor (Q) and new data, we present the experimental results to illustrate its validity.
