Abstract

We performed a study of the spatial uniformity of the averaged fields in a reverberation chamber at millimeter-wave frequencies based on measurements of the power transfer function for six different reverberation chamber loading configurations. We show that chamber spatial uniformity is strongly influenced by loading, such that an unloaded chamber can be considered as a nearly uniform environment, while uniformity decreases with increased loading. The loading of the chamber is key for wireless tests involving modulated signals. Its purpose is to create a frequency flat channel, which enables successful demodulation of the signal without distortion. Consequently, understanding this effect is important in quantifying measurement uncertainty in loaded conditions.
