Base station antenna

A base station antenna, comprising a plurality of linear arrays of radiating elements and a plurality of phase shifters, each phase shifter configured to pass radio frequency (RF) signals to a corresponding one of the plurality of linear arrays of radiating elements,

• wherein each linear array of radiating elements comprises one or more first sub-arrays of radiating elements and one or more second sub-arrays of radiating elements, each of the one or more first sub-arrays of radiating elements including n adjacent radiating elements, and each of the one or more second sub-arrays of radiating elements including m adjacent radiating elements, where n is greater than m,
• wherein said each of the one or more first sub-arrays of radiating elements in said each linear array of radiating elements is electrically connected to a respective one of a first subset of outputs of a respective one of the plurality of phase shifters that corresponds to said each linear array of radiating elements, and said each of the one or more second sub-arrays of radiating elements is electrically connected to a respective one of a second subset of outputs of the respective one of the plurality of phase shifters that corresponds to said each linear array of radiating elements,
• wherein the plurality of linear arrays of radiating elements are arranged spaced apart from each other in a first direction, and the radiating elements in said each linear array of radiating elements are arranged in a second direction that is substantially perpendicular to the first direction, and two adjacent linear arrays of radiating elements are staggered with respect to one another in the second direction,
• wherein first ones of the one or more first sub-arrays of radiating elements and first ones of the one or more second sub-arrays of radiating elements in a first of the plurality of linear arrays of radiating elements are arranged in a first order and second ones of the one or more first sub-arrays of radiating elements and second ones of the one or more second sub-arrays of radiating elements in a second of the plurality of linear arrays of radiating elements that is adjacent the first of the plurality of linear arrays of radiating elements are arranged in a second order that is different from the first order, and the first ones of the one or more first sub-arrays of radiating elements in the first of the plurality of linear arrays of radiating elements are located, in the first direction, on a direct left or right side of the second ones of the one or more second sub-arrays of radiating elements corresponding to the second ones of the one or more first sub-arrays of radiating elements in the second of the plurality of linear arrays of radiating elements.
