摘要：
In recent years, MIMO technology which uses multiple antennas has been introduced to the mobile terminal to increase communication capacity per unit frequency. However, if MIMO antennas are put closely, a strong mutual coupling occurred. Moreover, CA which uses multiple frequencies is also utilized to improve communication speed. Therefore, reducing mutual coupling in multiple frequencies is required. In this paper, we propose a dual-band decoupling method by using a short stub and a branch element and confirmed that the proposed model performed decoupling, increased radiation efficiency.
