Abstract

The invention provides a spiral antenna design method based on an adaptive evolution optimization algorithm. The spiral antenna design method comprises the following steps: firstly, establishing a structural model of a spiral antenna and an optimization mathematical model corresponding to the structural model; then, optimizing the antenna structure parameters in the optimization mathematical modelby adopting a reinforcement learning-based adaptive evolution optimization algorithm to obtain final optimized antenna structure parameters; and finally, according to the antenna structure parameters, adjusting the structure model to obtain the designed spiral antenna. The beneficial effects of the method are as follows: the parameters and the operation operator of the evolution algorithm are controlled by utilizing reinforcement learning; therefore, the self-adaptive differential evolution algorithm is realized, and a large amount of intermediate result data generated in the operation process of the self-adaptive differential evolution algorithm is used for guiding subsequent parameter setting of the evolution algorithm, so that the optimal antenna structure parameter of the spiral antenna is obtained, the efficiency is high, and the optimization performance is good.
