Reverberation chambers (RCs) are now widely used for the estimation of various antenna parameters such as radiation efficiency, gain, diversity gain, etc. The accuracy of such measurement relies on the assumption of a well-stirred field within the cavity. This paper evaluates the contribution of remaining unstirred path components as a function of the antenna position and the cavity wall shape. It shows their impacts on the estimated properties of an antenna, and discusses the ways to reduce their effects.
