Antennas are designed for specific system requirements such as gain, radiation pattern, bandwidth and input impedance and patterns. During this design and testing process, one of the most important steps is the measurement of its radiation pattern to define these critical parameters. Anechoic chambers are used for indoor testing purposes. Ideally they are isolated from all kinds of electromagnetic noise and have absorber coated walls inside. They also are used for radar cross-section (RCS) measurements and electromagnetic interference tests. This thesis examines the performance of the current Naval Postgraduate School anechoic chamber. Different absorbers and antenna patterns are simulated using the Urbana Wireless Toolset. It also includes a noise evaluation of the anechoic chamber. The results of this thesis can be used to guide the users of the existing chamber configuration in setting up tests and assist in any future redesign.
