The MIMO antenna comprises at least two single antennas arranged on a printed circuit board (PCB); the single antenna comprising: an antenna support, a feeding grounding branch node used for shielding low-frequency coupling between the single antennas, a feeding point, a grounding point and an antenna radiation part, wherein the antenna support is arranged on the PCB, and the antenna radiation part is arranged on the antenna support; and the feeding grounding branch node is connected with the antenna radiation part via the feeding point and the grounding point.

Abstract: The present invention discloses a multi-input multi-output antenna system comprising a first radiation unit, a second radiation unit, a radiation floor, a dielectric plate and a parasitic element. The first radiation unit, the second radiation unit and the parasitic element are printed on an upper surface of the dielectric plate, and the radiation floor is printed on a lower surface of the dielectric plate. The first radiation unit and the second radiation unit are planar monopole antennas, and the parasitic element is positioned between the first radiation unit and the second radiation unit. The system in accordance with the present invention can implement miniaturization of the antennas, and ensure two ports of an antenna have high isolation while maintaining good radiation performance.
