In this work, we study the effect of mutual coupling between multiple antennas on the outage capacity of a 2x2 multiple-input mUltiple-output (MIMO) system in flat fading channels. We model the effect of mutual coupling as an extra coupling matrix on top of the correlation matrix due to the propagation environment. The results show that mutual coupling reduces the correlation between the antennas from the propagation environment. On the other hand, mutual coupling also introduces extra power loss when the antennas are placed too close. The combination of these two effects on the outage capacity of MIMO systems is investigated. The simulations show that mutual coupling results in extra degradation of the outage capacity.
