Statistical analysis of three different stirrer designs in a reverberation chamber

A reverberation chamber (RC), is an economical facility in EMC, because it allows many directions for illumination an object with a higher field strength compared to conventional techniques, for the same input power. For emission measurements there is no need for moving an antenna. The field uniformity and statistical behaviour of the field are important in a RC. This paper presents an evaluation of the performance for three different stirrer designs inside a 1.00 m × 1.30 m × 1.50 m reverberation chamber. The evaluation was done in the frequency range from 300 MHz to 1000 MHz using both simulation and measurement results.
