ACO-BP算法对开口环形CNPDGS的优化

Optimization of Open Ring-like CNPDGS by ACO-BP Algorithm

组合式非周期缺陷接地结构(CNPDGS)是通过在微带电路的接地金属平面上人为地蚀刻出缺陷图案,来改变接地电流的分布,从而改变微带电路的频率特性,具有明显的禁带特性。本文讨论了蚁群算法和BP算法相结合的ACO-BP算法对开口环形CNPDGS单元进行优化设计,体现了该算法在全局优化方面的优越性。

Combinatorial non-periodic defected structure （CNPDGS）, which can change ground current distribution by etching flaw structure in the micro-strip circuit＇s ground, so as to change micro-strip circuit＇s frequency characteristic. The obvious forbidden band characteristic can also be obtained by CNPDGS. This paper discussed the ACO-BP algorithm which combines ACO algorithm with BP algorithm to optimize the open ring-like CNPDGS design, and it manifested the predominance in the global optimization.
