Power Loss in Reverberation Chambers by Antennas and Receivers

Reverberation chambers – design and application for EMC

Reverberation chambers are a promising EMC test environment which has several advantages. The set-up and design of reverberation chambers are discussed in the first part of the paper. The second part deals with their application for EMC. Several performance and comparison tests are presented and discussed which show a good reliability and reproducibility of the reverberation chamber as a test e...

Measurement of sound power and absorption in reverberation chambers using energy density.

Reverberation chamber measurements typically rely upon spatially averaged squared pressure for the calculation of sound absorption, sound power, and other acoustic values. While a reverberation chamber can provide an approximately diffuse sound field, variations in sound pressure consistently produce uncertainty in measurement results. This paper explores the benefits of using total energy dens...

Measurements of Radiated Power and Radiated Receiver Sensitivity in Reverberation Chambers

Chalmers and Bluetest AB have the last years shown that it is possible to measure radiated power and total isotropic receiver sensitivity in the statistic field environment created by a reverberation chamber. The new measurement method has been developed for mobile and wireless terminals such as mobile phones. However, the approach is also valid for measurements at higher frequencies, and e.g. ...

THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Characterization of MIMO Antennas and Terminals: Measurements in Reverberation Chambers

The reverberation chamber (RC) has drawn considerable attention as a multipath emulator over the past decade for both passive and active over-the-air (OTA) tests. This thesis is about RCs for OTA applications. The overview of this thesis is given in Chapter 1. Although the main purpose of this thesis is characterizations of MIMO (multiple-input multiple-output) terminals based on RC measurement...
