摘要/Abstract

摘要：

对矩形微带开口谐振环以及矩形地面缺陷开口谐振环的腔间耦合特性进行了深入研究．通过分析耦合谐振的电路模型，得到了耦合系数的计算公式；对矩形微带环、矩形地面缺陷环不同位置下的耦合特性分别进行了分析，系统总结了矩形谐振环之间不同位置形式下的耦合强度；根据不同腔间耦合形式设计了两个带通滤波器，验证了文中的研究．

关键词: 微带开口谐振环, 地面缺陷结构, 耦合特性, 带通滤波器

Abstract:

A systematic study of the square split ring resonator (SRR) which includes the microstrip SRR and SRR Defected Ground Structure (SRR DGS), and an analysis of the resonant and coupling properties of the SRR have been made. Calculation formulas for the coupling coefficient have been obtained by analysing the equivalent circuits. The coupling intensities between SRRs at different positions are analyzed, which has important meaning for filter design. Finally, two bandpass filters are designed using different coupling methods.

Key words: microstrip split ring resonator, defected ground structure, coupling properties, bandpass filter
