Influence on Q-Factor of Proximity and Orientation with Respect to Large-Form-Factor Loads in a Reverberation Chamber

Abstract

In this paper, it is shown that the presence of largeform-factor loads in close proximity to an antenna under test can affect the measured Q-factor (if measured improperly) in a reverberation chamber, possibly influencing the results of further calculations such as antenna efficiency. Furthermore, it is shown that the slope of the power delay profile of a measurement in a reverberation chamber is unaffected by the antenna's proximity to large-from-factor loads.
