The present invention discloses an antenna element preferably for a base station antenna. The antenna element comprises: a support structure being a single part and comprising a foot, a top and a wall connecting the foot to the top, the wall surrounding a hollow area; a first metallization arranged on a first surface area of the support structure, the first metallization forming at least a first radiating element extending along the wall from the foot to the top; and a second metallization arranged on a second surface area of the support structure, the second metallization forming at least a first feeding circuit for the first radiating element. The first surface area of the support structure and the second surface area of the support structure are arranged opposite to each other, and wherein either the first surface area or the second surface area is adjacent to the hollow area.
