| Abstract(in English) | Recent mobile terminal, the introduction of Diversity and MIMO technology using multiple antennas are examined. Because stable to communicate large data such as music and video are required to ensure better communication quality and communication capacity. If placed close to the MIMO multiple antennas in one location, Terminals can be gotten reducing antenna volume for improving design and reducing RF lines between antennas and radio for reducing propagation loss. But throughput may be reduced by lower radiation efficiency and higher correlation coefficient for antenna's coupling. In this paper, close to the 2 element monopole antenna placed parallel is studied for how to eliminate coupling for close placed MIMO antenna. When this decupling circuit is used in high coupling MIMO antennas, this circuit can be reduced coupling at 2 frequencies. And MIMO antennas can be gotten higher radiation efficiency, lower correlation coefficient, lower matching loss and its higher stability. |
