“…The corresponding expanded uncertainty of one specific RC facility is shown in Figure 1. Based on the statistical equivalence of RCs [6], we can conclude that the reproducibility of measurements within one specific RC facility at different locations is equivalent to the reproducibility of RC measurements in different chambers. This expanded uncertainty of 3 dB is comparable to the expanded uncertainty in the 10 m SAR [8].…”

The Reverberation Chamber (RC) method has many advantages above the Semi Anechoic Room (SAR) method. The RC method is specifically useful to measure emissions at high frequencies (>1GHz). This is an important property when we consider the trend of increasing operating frequencies of products and wireless applications. Furthermore, the RC method is useful for immunity tests, where we only need moderate power for generating suitable test levels. However, when different methods are used, the topic of conversion arises. In this paper, we specifically consider practical evaluation of the conversion factor of emission results of a CISPR 22 systemtest EUT configuration. In addition, we investigate the practical conversion factor of an artificial EUT. From these evaluations, it could be concluded that the RC method is suitable for performing compliance emission measurements and that a conversion factor of around 4 dB is applicable.

“…The procedure is applicable even for the case when more than one antennas are present in an RC. In (20), η o is the wave impedance, represents the permittivity of the RC propagation medium, and η depicts the efficiency of the antenna which can be estimated using (19). The term 1 − | S 11 | 2 in (20) also represents antenna efficiency (see 19).…”

“…This research topic has significantly constructive and standardized values, i.e., the experimental methods could be interchanged and selected where appropriate in terms of the different category of equipment under test (EUT) and its specific working electromagnetic environment applying the existing correlation coefficients between AC and RC. A statistical correlation [9] between AC and RC was demonstrated to be possible in automotive applications. A statistical theory [10] for assessing the directivity of emitters based on the electrical size of the device was reported.…”

This paper studies the correlation of a receiving thin dipole with an arbitrary load in both anechoic chamber (AC) and reverberation chamber (RC). In both cases, the method of moments is employed to calculate the current distributions along a thin dipole induced by external fields. In AC, a plane wave with a fixed incident angle and polarization is illuminated on the dipole; whereas in RC, the field is represented by an appropriate superposition of many incident plane waves with stochastic incident angles, polarizations and phases. Numerical results for the current distributions of a thin dipole with different loads and electrical lengths are presented and discussed in both chambers. It is demonstrated that the ratios with respect to current magnitudes at the arbitrary load of the thin dipole between AC and RC are determined by its directivity. In particular, the ratios with respect to current magnitudes along the entire dipole whose electrical length is less than half a wavelength are nearly constants regardless of the terminating load, which indicates that results obtained in both chambers are well correlated.
