A radiating element may have a dipole arm that may include a first conductive circuit loop and a second conductive circuit loop. The first conductive circuit loop may include at least one narrow conductive segment and at least one wide conductive segment, and the narrow conductive segment may present high impedance characteristics in at least one frequency band outside the operating frequency band of the radiating element to suppress at least partially the current in the at least one frequency band. A base station antenna may include a feed board and the radiating element mounted on the feed board.
