Radiated Power Measurements in Reverberation Chambers

The electromagnetic reverberation chamber is widely used for interference and compatibility compliance testing of electronic products. Such a chamber is particularly effective in quantifying the total radiated power from an emitter regardless of the emitter¿s radiation pattern. This feature is useful for characterization of wireless devices and other transmitters, especially as the front-end components and the antenna become more integrated and less accessible. We examine techniques for measuring radiated emissions using power received from an antenna in the chamber, and demonstrate a correlation to free-field measurements.
