MIMO ANTENNA ARRAY, MIMO ANTENNA AND BASE STATION

摘要

Provided by the present invention is a Multiple–Input Multiple-Output (MIMO) antenna array, comprising: a first antenna array that is formed by multiple first array elements and a second antenna array that is formed by multiple second array elements, the working frequency range of the first antenna array being at least partially identical to the working frequency range of the second antenna array; each first array element of the first antenna array and each second array element of the second antenna array are alternately distributed in sequence along the direction of a reference axis and do not interfere with one another; the transverse distance between the first array element and the reference axis as well as between the second array element and the reference axis is within the range of 0-0.3λ. The MIMO antenna array may reduce the gap between the widths of left and right boundaries of the first antenna array and the second antenna array so as to improve the symmetry of an image in the radiation direction such that the wave width convergence of half-power beam width is improved, and wave width is narrowed, while the front-to-back ratio and axial cross polarization are improved; furthermore, the windward area may be reduced so as to save antenna surface resources. Further provided by the present invention are a MIMO antenna and base station comprising the MIMO antenna array.
