Design of low cost 33° base station antenna

Current wireless communication market has a demand for high performance and low cost 33° base station antenna. In this paper the design topology of a low cost 33° base station antenna is presented. The frequency band is 1710–2170MHz. The single antenna element used in the antenna array is an aperture-coupled cross polarized patch antenna. The antenna array has a 3-column staggering structure with 30 elements in total. With a novel design of feeding network, a high performance and low cost 33° base station antenna was successfully developed.
