Antenna Efficiency Measurements in a Reverberation Chamber Without the Need for a Reference Antenna

This letter proposes a reverberation chamber approach for antenna efficiency measurement that does not require a reference antenna, that allows the antenna efficiency to be determined over a potentially wide frequency, range and which is applicable to electrically large antennas, thus demonstrating clear advantages over currently employed techniques for antenna efficiency measurement. This letter outlines the proposed method and presents results for a monopole antenna that demonstrate the efficiency can be obtained with reasonable accuracy over a range of frequencies.
