摘要
使用遗传算法 (GeneticAlgorithm)设计了智能天线系统前端的扇区天线阵列。该天线阵列用于TD SCDMA基站系统中。依据智能天线系统扇区覆盖模式(即广播波束 )对方向图的要求 ,利用GA的全局搜索性能 ,综合了阵列结构及单元激励相位。对该阵列结构使用GA模拟了智能天线系统工作模式 (业务波束 )下所要求方向图的阵列激励幅度和相位。给出了实际的智能天线系统前端扇区天线阵列结构 ,对智能天线技术的应用具有重要意义。
In this paper, Genetic algorithm is used to design the sectored array antenna in smart antenna system. The sectored array antenna is applied to the base station of TD SCDMA. Firstly, to meet the demand of smart antenna system sectored coverage mode (namely Broadcast Beam), the arrays configure and excitation phase are synthesized by the global search Genetic algorithm. Secondly, the weights needed to simulate the working mode(Work Beam) are optimized by Genetic Algorithm. The sector antenna array of practical smart antenna system is firstly proposed, which is meaningful for the use of smart antenna technology.
