The article presents the effect of radiation pattern of MIMO antenna system on the capacity for different channel models. A linear array of MIMO antenna system operating in UWB is deployed in a MATLAB simulation to examine the effect of antenna directivity on channel capacity. The One-ring and Kronecker models are used. On the other hand, mutual coupling between the antenna elements is considered in capacity calculation. A comparison between the capacity for nondirective and directive antennas is studied at different frequencies, which confirms the frequency dependency.
