Abstract
A dual polarized base station antenna is provided, including a reflector having a longitudinal axis and an array of tri-pole elements disposed on the reflector. Each tri-pole element has a first side arm and a second side arm. The tri-pole element also includes a center arm which is approximately perpendicular to the first and second side arms. The tri-pole elements are oriented such that either the side arms or the center arm are parallel to the longitudinal axis of the reflector. The antenna further includes a feed network having a first signal path coupled to the first arms of the tri-pole elements and a second signal path coupled to the second anus of the tri-pole elements. In this example, the array of tri-pole elements produces a cross-polarized beam at +45 degrees and −45 degrees from the longitudinal axis. Tri-pole arrays may be used in a multiband antenna.
