Considering the very short distance between transmitter and receiver in the near-field MIMO system, the impact of the radiation pattern of each antenna element is not neglectable. In this paper, the dual-dipole arrays are utilized to investigate the effect of HPBW (half-power beamwidth) on channel capacity. The HPBW can be changed by varying the internal distance between two dipoles in one element. With a proper HPBW of the antenna element, the channel capacity of a dual-dipole array is improved obviously from a conventional dipole array. And the optimum HPBW is found to be approximately 50°.
