| Abstract: | The design method of the reverberation chamber and the prediction analysis of its performance were described in detail. A real reverberation chamber was constructed according to the design. The performance of the reverberation chamber was calibrated strictly using the automotive measurement software. Some parameters such as field uniformity and quality factor were analyzed sufficiently. Measurement data indicate that the performance of the proposed reverberation chamber conforms to the IEC standard and show excellent repeatability in this chamber. The lowest usable frequency is 200MHz and the field uniformity is less than 3dB. This reverberation chamber can be used to evaluate the radiated emission or susceptibility of equipments under test. |
