摘要
分析了发卡式谐振器的四种耦合结构的基本原理及其电磁耦合特性,详细介绍了利用发卡式谐振器之间距离与耦合系数的关系曲线来设计微带型发卡式滤波器的方法,并给出了发卡式滤波器的设计实例及full-wave EM仿真结果。
The fundamental principles of four types of hairpin resonators' coupling structures and their electromagnetic coupling characteristic are analyzed. The approach to design the filter by using the relationship curve of these resonators' gap and their coupling coefficient is introduced. The design example and the result of full-wave EM simulation are presented.
