Title: Characterizing Large-Form-Factor Devices in a Reverberation Chamber
Published: July 15, 2013
Abstract: Abstract,With new technologies such as machine-to-machine communications there is a growing need to test large-formfactor devices in reverberation chambers. The performance of the reverberation chamber can be degraded by the physical characteristics of these devices. In this paper it is discussed how the spatial uniformity of the received stirred power and the received total power (stirred + unstirred power) are affected by a large object. A distinction is made between reflecting and absorbing objects. It is shown that large metallic objects cause minimal degradation in the spatial uniformity. Absorbing objects can cause substantial degradation in the spatial uniformity.
