摘　　要：根据我国提出的3G系统标准(TD-SCDMA)的技术规范,提出了一种用于3G系统基站的智能天线的设计方案,在设计中引入了智能天线的概念,采用了圆形阵列结构形式,利用优化算法和矩量法相结合的方法对阵元及阵列的性能进行了优化设计,并且对设计方案进行了系统仿真分析.仿真结果符合设计指标要求,从而证明了设计方案的可行性.该方案的提出对于指导3G系统中智能天线的设计工作具有指导意义.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.
