Abstract:

To address the challenges of high complexity and strong conflicting objectives in vehicular multi-antenna placement, an integrated intelligent optimization method is proposed based on neural networks and improved multi-objective particle swarm optimization (MOPSO) algorithm. Take the antenna coupling degree, radiation pattern distortion degree, and standing wave ratio as optimization objectives, and the antenna coordinates and input impedances as decision variables. utilize the radial basis neural network to predict antenna performance rapidly, thereby circumventing the computational bottlenecks of traditional full-wave simulation. The MOPSO algorithm is improved through adaptive grid algorithm and dynamic mutation mechanism to strengthen the global search capability, and approximate the Pareto optimal frontier efficiently. Furthermore, the Pareto optimal solution set is prioritized with fuzzy set theory. Experimental demonstrate that, compared to algorithms such as non-dominated sorting genetic algorithm-II, the proposed method achieves the best comprehensive optimization performance for all objective functions, with improvements of 23.2%, 20.6%, and 5.8%, respectively, which validates its effectiveness and superiority.
