Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, next generation systems have been actively studied to realize high speed and capacity data communication within mobile environments. MIMO (Multiple-Input Multiple-Output) systems with multiple antennas on the transmit and receive sides can perform parallel transmission at the same time and frequency by taking advantage of multi-path environment. The communication capacity depends on the mutual coupling and the correlation coefficient between antenna elements and varies with the propagation environment around the mobile terminal. In addition, the small terminal is affected by human hands. In this report, the interaction between MIMO antenna and human hands under the mobile urban environment is investigated. The correlation coefficient and radiation efficiency close to the simplified model of the human hand are calculated and measured changing the antenna configuration.
