Multi-Parameter Modeling with ANN for Antenna Design

In this paper, a novel artificial neural network (ANN) model with three parallel and independent branches is proposed. A data-classification technique is introduced to classify antenna geometrical variables into the proper categories. Once the geometrical variables are input, the ANN model can simultaneously obtain the antenna VSWR, gain and radiation pattern from each independent branch. The validity and efficiency of this proposed model are confirmed with an optimization design of an ultrawide band (UWB) antenna examnle.
