| 摘 要： | 本文设计了一种新型四分之一波长侧耦合线双模环形谐振器。根据滤波器的指标要求：中心频率、带宽、传输零点频率以及通带插八损耗，综合设计得出谐振器参数。将这种谐振器应用到传统的平行耦合微带线带通滤波器中，大大提高了滤波器的频率选择性。

| Abstract: | A dual-mode ring resonator fed by quarter-wavelength side-coupled lines is designed in this paper.The parameters of resonator are designed according to the requests for filter such as central frequency, bandwidth, transmission zeros frequencies and the insertion loss in the passband. The frequency selectivity can be increased by adopting this resonator in the traditional parallel-coupled microstrip line band-pass filter. |
