| 摘 要： | 文章提出将SIR谐振器结构应用于非对称共面波导传输线中，设计了一种新型SIR结构非对称共面波导带阻滤波器。通过四个SIR谐振单元在非对称共面波导传输线中级联，有效地改善了滤波器的插损和带宽。结果显示，本滤波器中心频率为1．8GHz，最小插损为0．4dB，相对带宽为33．3％，最大带外抑制为-60dB。具有小体积、低插损、高抑制、宽阻带、易于加工等优点。

| Abstract: | This paper proposes the application of SIR resonator in an asymmetric coplanar waveguide transmission line to design a novel asymmetric coplanar waveguide band-stop filter with SIR structure. By the cascading of four SIR resonance units in asymmetric coplanar waveguide transmission line, the insertion loss and bandwidth of the filter are improved effectively. The results show that the filter center frequency is 1.8GHz, the lowest insertion loss is 0.4dB, the relative bandwidth is 33.3%, and the highest rejection is --60dB. The present filter features small volume, low insertion loss, high rejection, wide stop-band, easy fabrication, etc. |
