1. A cellular antenna comprising:
at least a first array of elements arranged in horizontal rows and vertical columns; and
at least a second array of elements arranged in horizontal rows and vertical columns,
wherein said first array and said second array are arranged at least partially side-by side on said antenna,
wherein said elements of said first array are arranged in at least one vertical column of elements that is exclusive to elements of said first array,
wherein said elements of said second array are arranged in at least one vertical column of elements that is exclusive to elements of said second array, and
wherein said antenna includes at least one separate middle vertical column of elements, between the at least one vertical column of elements that is exclusive to elements of said first array and the at least one vertical column of elements that is exclusive to elements of said second array, wherein said middle vertical column of elements includes some elements in said first array and some elements in said second array,
wherein said antenna has three vertical columns of elements, and wherein said first array is a left side array and the at least one vertical column of elements that is exclusive to elements of said first array is a left vertical column, wherein said second array is a right side array and the at least one vertical column of elements that is exclusive to elements of said second array is a right vertical column, with said middle vertical column of elements therebetween
wherein said left side array and said right side array together form a 4×4 MIMO antenna,
wherein said 4×4 MIMO antenna has either an approximate 45 degree or 65 degree azimuth beamwidth; and
wherein distances between said left, right, and middle vertical columns of elements, combined with setting azimuth and vertical splitting power between the antenna elements of said left, right, and middle vertical columns of elements, is sufficient to provide said either approximate 45 degree or 65 degree azimuth beamwidth with increased gain relative to prior art 45 degree or 65 degree antennas, but without said antenna exceeding 500 mm in width.
