Summary:
In this paper we propose improvement method of MIMO channel capacity using tunable transmit-array antenna for an environment with the limited propagation paths. The channel capacity is maximized by tuning the termination condition of the antenna elements in the transmit-array. The improvement effect by the transmit-array with tunable elements on the MIMO channel capacity is evaluated based on the raytrace analysis in indoor environment. Also, the effect of the element spacing and aperture size of the transmit-array are studied to show the proposed transmit-array has a fair performance even with a feasible configuration.
