Design of new reverberation chamber for electromagnetic compatibility and wireless device measurement applications and its reproducibility performance validation

Abstract

This article proposes new reverberation chamber structure for electromagnetic compatibility and wireless device measurement applications. It consists of dual plate type mode stirrers and two types of reflectors that improve its original field uniformity. Based on the SD and eigenmode analysis, their effect is demonstrated, and through the final measured results, it is shown that the proposed reverberation chamber has excellent SD characteristic of <2.5 dB at 650 MHz or higher. In addition, from the viewpoint of its utilization, it is verified that for over the air performance of a commercial long-term evolution mobile phone, its experimental reproducibility is very high, and its results show little difference from those obtained in the anechoic chamber.
