This paper introduces a new high-isolation 2×2 multi-input multi-output antenna array design. The antenna array adopts multi-objective optimization method and fragment structure to achieve better performance. The results show that the isolation structure of this design can reduce the mutual coupling between different units of the antenna array. Compared with the traditional mutual coupling suppression technology in the microstrip array antenna, the isolation structure also improves the front-to-back ratio of the array.
