Abstract
This letter presents a tolerance mechanism-based enhanced multi-objective artificial hummingbird algorithm (TM-EMOAHA) for antenna optimization. The proposed method introduces an improved Pareto non-dominated solution determination strategy with a tolerance mechanism to precisely define dominance relationships through objective prioritization. A hybrid perturbation strategy integrating polar coordinate transformation and objective-oriented guidance is developed to enhance global search capability. The algorithm's effectiveness is demonstrated through a series-fed patch antenna design case. Experimental results validate that compared with traditional multi-objective algorithms, the TM-EMOAHA obtains a series-fed patch antenna with higher gain characteristics and lower sidelobe.
