摘要：
Radiation efficiency is one of the most difficult to measure quantities of antennas. Established methods are mostly either based on the Weehler-Cap-Method and limited to small antenna, or require a full 3D scan around he antenna under test. We present an alternative method for the measurement of antenna efficiency in the reverberation chamber. The measurement is based on an emission measurement method presented in [1]. Using this method, antenna efficiencies can be estimated along with the emission measurement of the equipment under test (EUT). This can help to reduce the uncertainty during radiated emission testing in the reverberation chamber. Of course, the method can also be used without an EUT present in the chamber to characterize the antenna only.
