Abstract

Determining the absolute antenna efficiency has been a difficult task since the inception of the antenna itself. While there are methods that can measure an antenna’s efficiency, most are complicated and prone to high uncertainties. A new method is presented for determining the lower bound of absolute antenna efficiency using a reverberation chamber. This method is able to characterize both the transmitting and receiving efficiency of an antenna. The proposed method is first validated using numerical simulations. These simulations can provide insight into the behavior of the equations and necessary assumptions. Then, the method for transmitting efficiency is validated using measured data from two different types of antennas: a wide band dual-ridged horn, and a narrow-band meta-material inspired antenna. Following the measurement data, possible areas for improvement of the method and it’s optimization are discussed.
