Artificial neural networks (ANNs) are implemented to minimize the size of the initial design. The ANN’s output with the physical and dielectric parameters of antenna as inputs is tested using COMSOL Multiphysics . The obtained results regarding the return loss S11, resonant frequency and bandwidth of the antenna are presented and discussed. Indeed, the size of the antenna is reduced by 21.48% with respect to the initial size while preserving its initial good performance in both frequency bands.Article
