Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the research and development of MIMO(Multiple Input Multiple Output) technology is advanced because of materializing high speed data communication under the limited frequency band. The MIMO antenna for mobile terminal using folded loop antenna has been proposed as basic study on mobile terminal installed MIMO technology. In this paper, the characteristics of the antenna performance on the hand-held condition have been calculated to investigate the MIMO chracteristics(Channel capacity) under the indoor actual propagation environment. Also, this paper examined causality of the directivity pattern of mobile terminal and inclination of polarization as the channel capacity. In the results, the MIMO antenna for mobile terminal using folded loop antenna had wide frequency bandwidth, low correlation and small influence of the human hand have been confirmed, and it has been able to be confirmed to restrain with several bps/Hz degradation in channel capacity of MIMO. Also, it has been able to be confirmed to get high channel capacity of MIMO when it equals the directivity pattern of mobile terminal and the inclination of polarization of incoming wave(XPR).
