Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the technology of MIMO (Multiple-Input Multiple-Output) using multiple antennas and CA (Carrier Aggregation) using multiple frequency bands are introduced in a mobile terminal. If plural MIMO antennas are installed closely, miniaturization of a terminal and improvement communication capacity can be realized. However, coupling between closely spaced antennas must be reduced to suppress deterioration of radiation efficiency and increase of correlation coefficient. In previous studies, a decoupling method between two elements monopole antennas for single-band using branch elements has been confirmed. This paper proposes a decoupling method for dual-band using trifurcation elements. It is realized that the proposed method provides higher radiation efficiency and lower correlation coefficient at two frequencies.
