In this paper we present simulation and measurement results of the channel capacity of a 3?3 MIMO antenna system. The aim of this research is maximization of a MIMO channel capacity for indoor environment. The dependence of the channel capacity on the antenna position was analyzed by simulations. We have also examined the effect of the frequency dependence of the antenna system (in case of conjugate-matching and non-conjugate-matching) for the channel capacity. Based on the simulation results in the created and measured antenna system the antennas were at a right angle to each other. At the two chosen different structures we measured the antenna parameters and the channel capacity. In this paper we present the results of the measurements which clearly confirm our simulations. We will point out to the differences between the two antenna structures.
