Abstract
An antenna for cellular communications is provided having a reflector and at least a first array of dipole antenna elements on the reflector operating at a first frequency ban. The dipole antenna elements of the first array having a printed circuit construction and composed of a balun feed and dipole arms. At least a second array of dipole antenna elements is provided on the reflector operating at a second frequency band the dipole antenna elements of the first array having a printed circuit construction and composed of a balun feed and dipole arms. The dipole antenna elements of the first array include one or more resonant structures causing a substantially closed circuit at the first frequency band and a substantially open circuit at the second frequency band. The resonant structures on the dipole antenna elements of the first array are located at least in part on the balun feed of the dipole antenna elements.
