CONCURRENT NEURO-FUZZY SYSTEMS FOR RESONANT FREQUENCY COMPUTATION OF RECTANGULAR, CIRCULAR, AND TRIANGULAR MICROSTRIP ANTENNAS

A method based on concurrent neuro-fuzzy system (CNFS) is presented to calculate simultaneously the resonant frequencies of the rectangular, circular, and triangular microstrip antennas (MSAs). The CNFS comprises an artificial neural network (ANN) and an adaptive-network-based fuzzy inference system (ANFIS). In a CNFS, neural network assists the fuzzy system continuously (or vice versa) to compute the resonant frequency. The resonant frequency results of CNFS for the rectangular, circular, and triangular MSAs are in very good agreement with the experimental results available in the literature.
