Coupling matrix extraction of coaxial cavity filter using chaotic ant colony algorithm

Traditional ant colony algorithm has many disadvantages such as poor population diversity and sensitive to initial value. It will be difficult to find optimal solution only relying on traditional pheromone update mode, and easily fall into local optimum. In order to solve these problems, an approach for extracting coupling matrix based on chaotic ant colony algorithm is proposed in this paper. This method effectively combines the hopping of the chaotic algorithm with the fast optimization of the ant colony algorithm, and solves the problem of single algorithm for initial value sensitivity and precocious maturity. Through the simulation experiment of cross and non cross coupled coaxial cavity filter, the method has strong global optimization ability, and has fast convergence speed and good optimization effect.
