【Abstract】 According to the procurement specification of third generation mobile communication standard—TD-SCDMA issued by CATT(China Academy of Telecommunications Technology), a design method of smart antenna used in the base station of TD-SCDMA system with the concept of smart antenna introduced is presented and the circular antenna array adopted. The optimal design for the performance of elements and antenna array is performed by using the method of combining optimal algorithm with method of moment(MOM). Also systematically simulating analysis for the design is processed. Due to the fact that simulating results satisfy specifications of the design, the feasibility of the design method is proved. The method given will give instruction for the design of smart antenna used in 3G system.更多还原
