Provided is a base station antenna radiator, which may provide polarization isolation with regard to a wide band. The base station antenna radiator comprises: a first radiation element and a third radiation element for radiating a first polarization signal; a second radiation element and a fourth radiation element for radiating a second polarization signal; first to fourth baluns coupled to the first to fourth radiation elements, respectively, and having vertical structures, respectively; a first feeder line including a vertical portion vertically extending from a first feeder and a horizontal portion bent from the vertical portion and extending in a horizontal direction, wherein the vertical portion passes through the first radiation element and the horizontal portion extends from an end of the vertical portion to the third radiation element; and a second feeder line including a vertical portion vertically extending from the second feeder, and a horizontal portion bent from the vertical portion, and extending in a horizontal direction, wherein the horizontal portion extends from a lower portion of the second radiation element to the fourth radiation element. The first to fourth radiation elements are positioned on the same plane. |
