Antenna (100) capable of producing a rectangular radiation pattern for use in a stadium, including a ground plane (1 10), a feed network (130) for processing RF signals in a plurality of frequency to or from two or more sets of outputs (140), each set providing RF signals on a respective one of the plurality of frequency bands. The antenna (100) also including at least two arrays (120) of radiating elements (122), each being fed by a respective one of the two or more sets of outputs of the feed network (130) for producing the rectangular radiation pattern in a respective one of the plurality of frequency bands. Each array having plurality of dual polarization radiating elements for producing dual polarization of the rectangular radiation pattern. The at least two arrays being suspended above one side of the ground plane, while the feed network feeding the at least two arrays being on the other side of the ground plane. |
