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。
With the development of modern wireless communication technology, the requirements for antenna design are getting higher and higher. The traditional design methods can no longer meet the needs of today’s antenna design. The use of microwave EDA software for antenna design has become an inevitable trend. In this paper, Taguchi method with global optimization is introduced in detail, and the idea of antenna optimization design combining HFSS electromagnetic field simulation software and Taguchi method is put forward. Taguchi optimized algorithm program is written as external optimizer under the Matlab environment, and the optimal design of GPS microstrip antenna is realized by calling HFSS software. It not only takes advantage of the calculation of simulation software, but also ensures the correctness of the antenna solution, and also uses the optimization algorithm Fast convergence characteristics, save the calculation time, improve the design efficiency.
