EM-ANN modeling of overlapping open-ends in multilayer microstrip lines for design of bandpass filters

This paper describes electromagnetic-artificial neural network modeling based on EM simulation results (EM-ANN) for overlapping gap coupled sections of microstrip lines used in the design of multilayer end-coupled band-pass filters. The overlapping gaps are used for obtaining a wide bandwidth. An EM-ANN model has been developed successfully for reducing the design time. Also, a design for multilayer end-coupled band-pass filter has been performed using this model and compared to the design without using ANN models.
