摘要
本文通过在微带(hairpin)滤波器的谐振器上并联微带开路线,构成了一种新的hairpin带通滤波器。该滤波器在通带附近有一对传输零点,具有良好的频率响应以及频率选择特性。由于这种类型的微带滤波器实现传输零点不需要通过滤波器非相邻谐振器间的交叉耦合来获得,因此,设计过程非常简单。
A new configuration of microstrip hairpin bandpass filter is presented. The new filter is realized by adding open microstrip lines on the resonators of the conventional microstrip hairpin bandpass filter. The filter has a pair of transmission zeros around the passband, excellent frequency response and frequency selectivity. As this kind of microstrip hairpin filter does not require cross coupling between the non-adjacent resonators of the filter to obtain transmission zero, the design procedure of the filter is simple.
