Investigation of the Effect of Changing the Stirrer Shape on a Reverberation Chamber With CST Simulation

The reverberation chamber is a test environment that is constructed as an alternative to a fullyreflective or semi-reflective room, coated with internal and external materials with high conductivity, and hasa homogeneous electric field structure limited by certain standards. The biggest advantage is that theinstallation costs are much lower than the full non-reflective room. It is necessary to obtain uniformity ofelectric field in the room so that a room can be a reverberation chamber. A reverberation chamber basicallycontains a few components such as stirrer, transmitter antenna and receiver antenna. According to theoptimization of the components, the uniformity of the electric field inside the room can be provided. Theparameters such as position, shape, size, angle of the stirrer which is one of the most important elements in thechamber, affect the uniformity of the electric field. In this study, the effect of the stirrer shape on the electricfield uniformity was investigated and the results were compared.
