Base station antenna

A base station antenna comprising a first column and second column of radiating elements adjacent in the horizontal direction and a first phase shifter and a second phase shifter that are electrically connected to the first column and the second column, respectively, wherein each column of radiating elements includes a plurality of radiating elements arranged in the vertical direction, and the first and second columns of radiating elements are staggered from each other in the vertical direction,

• wherein each column of radiating elements comprises one or more first subset composed of n adjacent radiating elements, and one or more second subset composed of m adjacent radiating elements, wherein n is greater than m,
• wherein the first and second subsets of the first column of radiating elements are alternately arranged in the vertical direction in a first pattern, and the first and second subsets of the second column of radiating elements are alternately arranged in the vertical direction in a second pattern,
• wherein the first pattern is different from the second pattern, so that in the horizontal direction, each first subset in the first column of radiating elements is located on the direct left or right side of the second subset of the second column of radiating elements corresponding to the first subset in the first column of radiating elements,
• wherein each subset of the first column is electrically connected to a respective output of the first phase shifter, and
• wherein each subset of the second column is electrically connected to a respective output of the second phase shifter.

A base station antenna comprising:
