基于田口优化方法的GPS 微带天线仿真设计

随着现代无线通信技术的发展,人们对天线设计的要求也越来越高。传统的设计方法已经不能满足当今天线设计的需要,使用微波EDA软件进行天线设计已经成为必然趋势。本文详细介绍了具有全局优化功能的田口方法,并提出了将HFSS电磁场仿真软件与田口方法相结合进行天线优化设计的思想。在Matlab环境下编写田口优化算法程序作为外部优化器,通过调用HFSS软件实现了GPS微带天线最优设计;既利用了仿真软件的计算优势,确保了天线求解的正确性,又利用优化算法的快速收敛特性,节省了计算时间,提高了设计效率。

Simulation and Design of GPS Microstrip Patch AntennaBased on Taguchi s Method

With the development of modern wireless communication technology,antenna design requirements are high er and higher. Microwave EDA software for antenna design has become an inevitable trend because traditional design methods can t meet the needs of modern antenna design. A global optimization function of taguchi's method is described in this pa per. Optimized antenna design idea is proposed by using HFSS electromagnetic simulation software combined with the tagu chi s method. Optimal design of GPS microstrip antenna is achieved by calling the HFSS software with taguchi optimization procedure written in matlab environment as an external optimizer. It ensures the accuracy of the antenna solution by using the simulation software. And also, it saves computing time and increases design efficiency by using the optimization algorithms.
