Measurement of Wireless Devices in Reverberation Chambers

Abstract

When the antenna is integrated into the body of a wireless device, as it is for cell phones and many other portable devices, performance testing is typically done under free-field conditions. In this overview presentation, we will discuss free-field characterization of some key wireless- device parameters by use of reverberation chambers. Measurements in reverberation chambers must be averaged over a sufficient number of samples in which the modes of the chamber are randomized or “stirred.” We will discuss recent research on the use of these chambers for testing devices that transmit modulated signals.
