Abstract

With the advent of the 3G mobile telecommunication system, the antenna array of the base station is required to be smart and intelligent. And the antenna pattern should be shaped to have filled nulls over the down side and low sidelobe levels over the upper side. Phase weighting of shaped pattern for base station antenna arrays is presented. It is achieved by using the combination of the genetic optimization and particle swarm optimization and statistically sampled optimization algorithms. Phase weighting is easy to be implemented in the feed network of the antenna and efficient for the engineering practice. It is preferred in the antenna design. The example is given and the associated figure also shown.
