Abstract
The capacity of multiple-input multiple-output (MIMO) systems is strongly dependent on the channel matrix which in turn can be expressed in integrals over the antenna far-field patterns. The effect of mutual coupling on the capacity of a 2×2 MIMO system is studied. The results show that, even though the correlation is reduced, the losses caused by mutual coupling decrease the capacity as we reduce the antenna spacing.
