With new third and fourth generation mobile communication systems emerging; there has been an increased focus on the antenna performance of mobile terminals. Common for most new communication systems currently deployed and under development is the demand for multi-antenna technology, such as multiple-input-multiple-output (MIMO). In order to reach increased data rates it is essential to be-able to make use of the potential spatial multiplexing gain of a multipath propagation environment. For design optimization of these multi-element antennas, a reliable and relevant measurement method for characterizing the antenna performance is important. In this paper, a method using the reverberation chamber is presented together with a discussion on how to analyze the results in order to distinguish good and bad antenna designs from each other.
