Abstract: A multi-input multi-output (MIMO) antenna system includes multiple antennas, a ground part and an isolating part. The isolating part is disposed between each two adjacent antennas. The isolating part is electrically connected to the ground part. A distance exists between an end of the antenna and an end of the isolating part. A circuit board applying the MIMO antenna system is also disclosed. Since the isolating part is disposed between each two adjacent antennas, signal interference between the antennas can be prevented, and the MIMO antenna system and the circuit board applying the same have better isolation.
