Abstract: The traditional optimization algorithms might fail to obtain the global optimal solution for highly nonlinear optimization problem in antenna design, so a cultural based particle swarm optimization (CBPSO) algorithm is induced, and by constructing Kriging model to replace time-consuming HFSS simulation evaluation, the model is updated to improve the approximation accuracy. Proposed a optimizing project based on the combination of dynamic Kriging model-CBPSO with high frequency struc－ture simulator (HFSS), use this project to design a WLAN/ WiMAX antenna, which covers the frequency band from 2.4 to 3.0GHz,3.3 to 3.8GHz,5.1 to 6.0GHz with -10dB return loss. It's proved that this project can be used to optimize the complicated structure antenna.
