Predicting low frequency behavior of arbitrary reverberation chamber configurations

This paper demonstrates that a simple signal ratio can transform low frequency monopole antenna data between different reverberation chamber configurations. Applicable chamber differences include DUT and antenna position, size and shape of chamber. The signal ratio deduced empirically or analytically, is shown to be accurate to about 5 MHz. Method efficacy is demonstrated using measurements for variations in antenna position and chamber size. Finite element calculations of signal ratios are compared to measurements. The signal ratio is useful in correlating results between chambers and test configurations. Results indicate that low frequency correlation of different chambers should be straightforward.
