Characterization of spurious emissions of wireless devices in a reverberation chamber

Abstract

The reverberation chamber has been widely studied and described in the past as an efficient measuring tool in EMC, particularly for shielding effectiveness or immunity testing. The new IEC 61000-4-21 standard, published in 2003, acknowledges the possibility to carry out emission measurements for various devices; this paper proposes to analyze intended spurious emissions of two types of WiFi modules with the reverberation chamber.
