PROBLEM TO BE SOLVED: To achieve an antenna arrangement for preventing performance of MIMO from being deteriorated in a propagation environment where direct wave is dominant.SOLUTION: An antenna arrangement is provided which is for a short-range MIMO where direct wave is dominant. At this antenna arrangement, a distance (r) between a transmitter and a receiver, propagation coefficients (α, &bgr;, γ ) between the transmitter and the receiver, an offset (δ) between the transmitter and the receiver, and a distance (d) between antennas on the transmitter side or a distance (d) between antennas on the receiver side are included in parameters. Then, at least two parameters are assigned from these parameters. As a result, the antenna arrangement is determined which increases or decreases channel capacity (c). |
