Abstract

With the proliferation of wireless devices in recent years, there is a growing need to test the operation and functionality of these various devices in different multipath radio propagation environments, ranging from a direct line-of-sight environment to a pure Rayleigh environment, as well as anything in between (i.e., Rician). In this paper we discuss how an electromagnetic reverberation chamber can be used to simulate a controllable Rician radio environment. It will be shown that by varying the characteristics of the reverberation chamber and/or the antenna configurations in the chamber, any desired Rician K-factor can be obtained for the testing of a wireless device. Expressions for the desired K-factor as a function of the chamber and antenna characteristics will be presented. Experimental results will be presented to illustrate the validity of these expressions, to show how the reverberation chamber can be used to simulate different environments, and to show the realization of a controlled K-factor test facility. We will present both a one-antenna and a two-antenna test configuration approach.
