EMC Testing of Wireless Systems by the Use of Reverberation Chambers

In the EMC laboratory of the Department of Electrical Engineering of the University of Rome “La Sapienza,” the existing shielding room has been transformed into a reverberation chamber. An aluminum stirrer and a stepping motor were installed in the existing chamber to provide an appropriate mechanical stirring of the EM field. The performances of the reverberation chamber have been characterized by means of calibrations and Q-factor calculations. This paper presents the details of the chamber realization, of the measurement set-up, and reports the early characterization tests performed up to now. Some problems encountered during the chamber realization, along with the adopted solutions are also described.
