Abstract
An array of antenna elements including a feed board that includes a power divider network and a balun section. According to one aspect of the invention, there is provided a horizontally polarized antenna arrangement including a feed board, a plurality of horizontally polarized antenna elements, and a reflector. The antenna elements are a plurality of dipole pairs. The feed board has two faces. The first face includes a power network and a balun section, that feeds power to the plurality of antenna elements, and the second face includes a ground plane. The fact that the feed board includes a balun section allows the antenna elements to be etched on an inexpensive board or, in the alternative, allows the antenna elements to be individual wires or plates. The antenna arrangement also includes two tuning means, line extensions in the power network and tuning stubs etched to the ground layer, which make it easier to tune the antenna. In addition, one embodiment of the invention is configured so that the dipole arms are soldered to the feed network at points that are farther away from each other than existing antenna arrangements. This lowers the risk of solder bridging.
