Özet

A method based on adaptive-network-based fuzzy inference system (ANFIS) is presented for the quasi-static analysis of conductor-backed coplanar waveguides. The ANFIS is a class of adaptive networks which are functionally equivalent to fuzzy inference systems. Pour optimization algorithms, hybrid learning, genetic, simulated annealing and least-squares, are used to determine optimally the design parameters of the ANFIS. The results of ANFIS are compared with the results of experimental works, quasi-static and fulll-wave spectral domain approaches, conformal mapping technique, and a commercial electromagnetic simulator IE3D. The results of ANFIS models are in very good agreement with the results of other methods and experimental works. When the performances of ANFIS models are compared with each other, the hest result is obtained from the ANFIS model trained by the hyhrid learning algorithm. (C) 2008 Wiley Periodicals, Inc.
