【摘要】 宽带定向耦合器工作频段宽、设计参数多,传统的设计方法很难实现。遗传算法作为一种随机搜索方法,能够处理大规模优化问题,并且得到全局优化解。本文用遗传算法对定向耦合器进行了参数设计和容差分析,并得到了比较满意的结果。更多还原

【Abstract】 Broadband directional coupler is difficult to design using conventional methods due to very broad band and too many parameters.A Genetic Algorithm(GA) is a stochastic search method,can deal with large optimization problems and obtain global optimum result.In this paper,GA is applied to the parameter design and tolerance analysis of broadband directional coupler,and the results prove these methods are feasible and effective.更多还原
