| Abstract(in English) | In recent years, in wireless information terminals, MIMO technology using multiple antennas is used to stably communicate large capacity data. In addition to communication performance, since terminals are also required to be miniaturized, downsizing of the antenna volume is also required due to close placement of antennas. However, some problems arise such as strong electromagnetic coupling occurs between the antennas, the antenna efficiency is reduced, and a desired communication distance and capacity cannot be obtained. As a countermeasure against these problems, in this report, we propose a method to reduce couplings between all antennas, for three monopole antenna elements arranged linearly on a plane assuming 3 × 3 MIMO, that does not require a connection between the antennas at both ends and does not need a 3D structure to jump over the central antenna. |
