Comments on "A Hybrid Method Based on Combining Artificial Neural Network and Fuzzy Inference System for Simultaneous Computation of Resonant Frequencies of Rectangular, Circular, and Triangular Microstrip Antennas

The recent paper by Guney and Sarikaya claims to present a new soft computing method for evaluating the resonant frequencies of rectangular, circular, and triangular equilateral microstrip antennas. As stated by the authors, the method is based on a combination of artificial neural network and fuzzy inference system. Afterwards, the authors developed a hybrid model able simultaneously to predict resonant frequencies for the three printed antenna geometric configurations considered.
