摘要
将微分进化策略与连续蚁群优化算法相结合,提出了改进的微分进化策略算法,避免了早熟现象的出现,提高了收敛速度,并以此改进优化算法优化了宽带全向天线的加载位置、加载集总元件值等参量,优化结果表明,天线方向图在20:1的频带内无凹陷,电压驻波比小于3.0。
A modified differential evolution strategy （MDES） algorithm based on DES and continuous ant colony optimization （CACO） algorithm is proposed in this paper. The possibility of premature can be reduced and the convergence rate is improved. The loading location, loading resistance and reactance values ofwideband omnidi- rectional antenna are optimized by the MDES algorithm. The optimization result shows that the antenna＇s gain radiation patterns are not cupped in the 20：1 frequency bandwidth, and the VSWR of antenna is less than 3.0.
