An Antenna Optimization Method Based on Optuna-ANN

An artificial neural network (ANN) model combined with Optuna optimization algorithm (Optuna-ANN) is proposed to optimize the S-parameters of the antenna. Optuna-ANN can achieve more accurate prediction and improve the calculation efficiency. Compared to the traditional ANN models, this method can solve the problem that a large amount of computing resources will be occupied faced with the traditional ones. In addition, the simulated S-parameter result of a microstrip antenna is introduced for validation of the Optuna and conventional ANN models.
