An improved Particle Swarm Optimization (PSO) with high efficiency and low time consumption is presented in this paper. The optimization adopts the method of interval prediction, and it combines multiple parameters into a new fitness value to judge the optimization direction. In order to verify the proposed optimization, S11and bandwidth of a classic patch Yagi antenna are simultaneously optimized by the improved PSO method. It shows that the optimization speed is increased by 80% comparing to traditional PSO.
