| Abstract(in English) | We have examined the efficiency in the introduction of the directional antenna to the base station for the indoor propagation environment. When the directional antenna is used for an actual environment, there are a lot of variety of room shapes, such as, office, meeting room, and etc. Then, the beamwidth and the beam direction of base station antennas should be optimized to maximize the channel capacity depending on the room shape. This paper presents the optimum beam width and the direction of base station antenna for various room shapes using by ray-tracing method to obtain the maximum channel capacity in MIMO system used under indoor propagation environment. |
