Theory and Measurements of Antenna Radiation Pattern in a Perfectly Chaotic Reverberation Chamber

This article presents first how antenna radiation pattern could be theoretically performed in a reverberation chamber which could be considered as perfectly chaotic. In such kind of reverberation chambers, the appearance of unstirred paths should be totally cancelled and anechoic measurements could be easily performed at the price of the repetition of the measurements for different stirring conditions and the computation of the average of these measurements. Encouraging measurement results on a double-ridged horn antennas at 12 GHz obtained in a vibrating intrinsic reverberation chamber (VIRC) are then presented. Indeed, a VIRC is a good candidate to be considered as perfectly chaotic.
