Characterization of Reverberation Chambers at 60 GHz for Wireless Device Testing

Reverberation chambers (RC) have been widely used to perform Electromagnetic Compatibility (EMC) testing due to their statistically uniform, isotropic, and well-scattered fields. Recently, because they can emulate realistic multipath propagation environments and provide repeatable test environments, their use in wireless device testing has increased rapidly. However, as the operating frequencies of wireless devices increase, it becomes essential to study and characterize RCs at these frequencies. This paper presents the characterization of a 60 GHz RC for millimeter-wave (mmWave) wireless testing through key metrics such as the quality factor (Q) and the Rician K-Factor, highlighting the differences with respect to lower frequency ranges. The testing on a real device confirms the results obtained during chamber characterization.
