Reverberation chamber field modeling for application to the source stirring technique

The paper describes an analytical model applied to study the behavior of an antenna moving inside a resonant cavity. It is the basic step to develop a source stirring mode reverberation chamber (RC). The model is able to account for the different coupling of the source with the many cavity modes. The results obtained for a simple dipole are used to design an array of 50 dipoles, whose generated electromagnetic field shows a good statistics when checked by the CDF and by means of a polar plot diagram. The antenna array allows to use a fixed source for the chamber. Finally, the paper presents how to practically fabricate a well working array using broadband antennas, more suitable for actual RC applications.
