Calibration of a Reverberation Chamber for Radiated Emission Measurements by Wall Mounted Antennas

This paper reports a novel technique to estimate the total averaged power emitted by a device under test placed inside the working volume of a reverberation chamber in a radiated emission test. The electromagnetic field inside the chamber is stirred by the application of the multiple monopole source stirring in receiving mode, that is a particular way to implement the source stirring technique; in this scenario an array of monopole antenna is placed onto the chamber walls and sequentially connected to the measurement system to get the stirring action. The procedure for the radiated emission estimation requires that chamber has to be calibrated by a set of measurements. In the paper the calibration results are compared to the prediction of the analytical model, developed to predict the chamber's performances.
