Effect of Stochastic Diffractors on Antenna Measurements in a Source Stirred Reverberation Chamber

We analyze the measured reflection coefficient of antennas in unconventional multiple monopole source stirring reverberation chambers. The reverberation chamber that we used is equipped by stochastic diffractors that are used to break the geometrical symmetries of the baseline metallic cavity. The experimental measurements of the average reflection parameter show reduced frequency fluctuations over a broad frequency range. Furthermore, the average reflection coefficient measured in the reverberant environment is in good agreement with the measurement of the same antenna in free space conditions.
