Design of 900 MHz-band one-sided directional slot antenna by Bayesian optimization

In this paper, we proposed to design the one-sided directional slot antenna for 900 MHz band application by Bayesian optimization, one of the machine learning-based optimization methods, to reduce the simulation time by electromagnetic field analysis. Bayesian optimization, an efficient black-box function optimization technique, is applied to the antenna design to reduce the design time and simplify the design. We confirm the effectiveness of this method by fabricating and experimenting with the designed antenna.
