Abstract

This article presents a new method based on adaptive neuro‐fuzzy inference system (ANFIS) to calculate the effective permittivities and characteristic impedances of microstrip lines. The ANFIS is a fuzzy inference system (FIS) implemented in the framework of an adaptive fuzzy neural network. It has the advantages of expert knowledge of FISs and learning capability of artificial neural networks. A hybrid learning algorithm, which combines the least square method and the back propagation algorithm, is used to identify the parameters of ANFIS. The results of ANFIS are compared with the results of the experimental works, quasi‐static methods, and a commercial electromagnetic simulator IE3D. There is very good agreement among the results of ANFIS models and quasi‐static methods, IE3D, and experimental works. © 2008 Wiley Periodicals, Inc.
