Abstract
An antenna assembly is provided which includes: a feeder panel; an array of radiating elements mounted on the feeder panel; a plurality of metal tubes mounted to extend forwardly from the feeder panel, where at least a portion of radiating elements in the array of radiating elements are surrounded by at least four metal tubes spaced apart, respectively. In addition, a base station antenna including the antenna assembly may be provided. The antenna assembly is capable of effectively improving the cross-polarization performance of the base station antenna and improving the radiation boundary of the base station antenna.
