Abstract :
We describe how to measure the radiation efficiency, correlation, diversity gain and capacity of a six-monopole antenna array in a reverberation chamber in order to characterize it by these parameters for a MIMO system. We show how these measurements can be used to find the channel capacity when a particular antenna array is used in a MIMO system. We also explain how numerical modeling of the MIMO array in a commercial code can be used to find the channel capacity.
