A cellular antenna having at least one MIMO array has at least a first group of elements arranged in horizontal rows and vertical columns and at least a second group of elements arranged in horizontal rows and vertical columns. The first group and the second groups are arranged at least partially side-by side on said antenna. The elements of the first group are arranged in at least one vertical column of elements that is exclusive to elements of the first group. The elements of the second group are arranged in at least one vertical column of elements that is exclusive to elements of the second group. The antenna includes at least one separate common vertical column of elements, that includes elements of both said first group and the second group of elements.
