Claim:
1. A multiple-input multiple-output (MIMO) antenna, comprising 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; wherein the antenna radiation part comprises a monopole part, a coupling gap, a coupling branch node, an open stub, and a grounding branch node; wherein: the monopole part is connected to the feeding point, extends from the feeding point and along a front surface of the antenna support, changes its extending direction on to a top surface of the antenna support, and extends from the top surface of the antenna support to form a transverse radiation patch; the coupling branch node is connected to the grounding branch node, and extends from the grounding branch node along the top surface of the antenna support to form a lateral branch node; the lateral branch node is separated from the transverse radiation patch of the monopole part via the coupling gap; the open stub is connected to the grounding branch node, extends from the grounding branch node and along the top surface of the antenna support, and changes its extending direction on to a right surface of the antenna support; and the grounding branch node is connected to the coupling branch node and the open stub, extends from the top surface of the antenna support, change its extending direction on to the front surface of the antenna support, and then is connected to the feeding grounding branch node.
