Summary:
A wireless channel can be parallelized by using MIMO technology. In contrast to the conventional MIMO, however, the near-field MIMO system operates in near-field region of antenna elements, and each antenna directly communicates with each other. In order to construct a near-field 2x2 MIMO system, the antenna array, which is composed of short electric dipole and small loop (short magnetic dipole) antennas, can be used as the transmitting and receiving arrays. When the small antennas are used, the characteristics of the channel matrix can be simply analyzed based on the addition theorem, and thus the capacity can be also easily estimated.
