Abstract (in Japanese) (See Japanese page) 
(in English) We proposed a novel communication scheme, which uses short range MIMO transmission. In the short range MIMO transmission, the distance between two facing array antennas is comparable with the size of the array antenna aperture. We found that the channel capacity with an optimal antenna spacing is higher than ergodic capacity in i.i.d. channel since the short range MIMO scheme has a high similarity with a parallel data transmission. In this paper, the channel capacity and transmission rate are compared due to actual transmission schemes which are used in MIMO systems. When the optimal element spacing is obtained, the channel capacity by Zero forcing (ZF) is almost same with that by Eigen-mode beamforming (EM-BF). On the other hand, we clarify that \emph{perfect} parallel transmission is very difficult because inter-stream interference occurs even in wide antenna spacing. We show that the optimal element spacing is a key parameter in the short range MIMO communication; it is very effective to design array antennas with the optimal element spacing for a simple hardware configuration.
