Abstract: CMEA（Chaos Mind Evolutionary Algorithm） is an optimal algorithm，mixing Mind Evolutionary Algorithm with Chaos Optimization Technology，can remarkably solve the disadvantages of MEA，such as the generation of the initial population is blind，random and redundant，so it is easy to get into part extremum solution.This proposed algorithm，compared with MEA，can remarkably avoid local convergence while producing a high convergence rate.The optimization design of Yagi-Uda antenna is performaced based on CMEA.With the model building and optimization in HFSS and MATLAB，the structure parameters of Yagi-Uda antenna with excellent performance are got.The results of simulation prove the advantage of CMEA in antenna engineering.

摘要： 混沌思维进化算法将混沌搜索和思维进化算法相结合，有效地解决了思维进化算法中初始种群产生的盲目随机性和冗余性以及现有搜索方式易陷入局部最优的问题。该算法与标准思维进化算法相比，能有效地避免局部收敛，具有更快的收敛速度。把混沌思维进化算法应用到八木天线的优化设计中。通过在HFSS和MATLAB中的建模和优化设计，得出具有优良性能的天线结构，也验证了混沌思维进化算法在天线工程领域具有较高的应用价值。
