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。
組閤式非週期缺陷接地結構（CNPDGS）是通過在微帶電路的接地金屬平麵上人為地蝕刻齣缺陷圖案,來改變接地電流的分佈,從而改變微帶電路的頻率特性,具有明顯的禁帶特性。本文討論瞭蟻群算法和BP算法相結閤的ACO-BP算法對開口環形CNPDGS單元進行優化設計,體現瞭該算法在全跼優化方麵的優越性。

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.
