Effect of U-slot applications on circular microstrip patches modeling with artificial neural networks on impedance bandwidth

In this study, effects of etching U-slot on circular patches on their bandwidths are investigated. The study is carried out by etching U-slots on the present microstrip patches in the literature by simulating them with HFSS. Simulation results are used for training and testing of an Artificial Neural Network model for different microstrip patches' bandwidth predictions. The obtained simulation results are compared with Artificial Neural Network results. In comparison of the simulation and Artificial Neural Network results, accuracy rates of training and testing were found as 93.28% and 94.19%, respectively. It is obtained that by etching U-slot, the band- widths can be enhanced for the present circular microstrip patches. It is shown that possible the bandwidth behavior of U-slot circular microstrip disc antenna with this Artificial Neural Network model is powerfully estimated.
