A one-stop computer simulation method for multiple-input and multiple-output (MIMO) channels including a full-wave characterisation of the antenna characteristics is introduced. Unlike previous channel simulation methods which use antenna radiation patterns, the effect of the antenna response on the MIMO performance in this method is directly built into channel simulation through numerical calculation. This enables the effects of the antenna gain, antenna radiation characteristics, antenna mutual coupling, antenna terminal load, antenna dimensions, etc, to be directly included into the channel response without any additional analytical supplementary procedure. This method starts simulation from the input ports of the transmitting antennas and traces the multipath signals all the way from the transmitting antennas to the signal voltages developed at the terminal ports of the receiving antennas in a one-step complete simulation. The validity and accuracy of this method are demonstrated by numerical examples.
