摘要
本文提出了一种具有高选择性的耦合微带线带通滤波器。该滤波器是以传统的耦合微带线滤波器为基础,在其两个开路端连接了一对其中一端短路的耦合微带线。因此,在传统耦合微带线滤波器的传输系数基础上加入了一对传输零点,同时增加了该滤波器的选择性。为了进一步增加滤波器的选择性,在上述滤波器结构的基础上,在上述的两个短路端各连接一段λ/4的传输线,这样在之前的基础上又会加入一对传输零点。同时,该耦合微带线带通滤波器的选择性将进一步得到提高。
A parallel-coupled microstrip bandpass filter with high selectivity is proposed in this letter. The proposed bandpass filter is based on the traditional parallel-coupled bandpass filter while a parallel-coupled microstrip line with one side shorted is inserted to the traditional parallel-coupled bandpass filter. Therefore, a pair of transmission zeros have been added and the selectivity of the bandpass filter has been improved. In order to improve the selectivity further, a pair of λ/4 transmission lines have been connected to the shorted side of the inserted parallel-coupled microstrip line and another pair of transmission zeros have generated. As a result, the selectivity of the bandpass filter has been enhanced.
