Abstract (in Japanese) (See Japanese page) 
(in English) The recent increase of needs for the wireless communication quality has induced the development of multi-antenna system for handsets such as diversity and multiple-input multiple-output (MIMO) applications. Since the mutual coupling occurring between the radiators affects on the antenna performances, it is necessary to consider some simple methods of reducing the mutual coupling without the performance degradation, especially when we attempt to introduce multiple antennas on a mobile handset terminal. This study analyzes about the reduction of the mutual coupling between two L-shaped folded monopole antennas (LFMAs) for handset. As the analytical results, we found that, from the viewpoint of the mutual coupling and the total antenna efficiency, it is desired to place the shorting strips of LFMA elements facing each other. Moreover, by linking the two antennas with a bridge line, we obtained a sufficient reduction on the mutual coupling and greatly improved total antenna efficiency.
