摘要
本發明係揭露一種寬頻帶高頻濾波器，其包含開路共振結構以及短路共振結構。開路共振結構具有帶狀訊號傳輸線以及T形帶狀線，帶狀訊號傳輸線之兩端係向T形帶狀線之相對兩端彎折，以分別形成缺口。同時，本發明利用開路共振結構以及短路共振結構在其共振模態下耦合，而達到過濾中心頻段為60GHz濾波效果。
The present invention discloses a wideband high frequency bandpass filter, which includes an open-circuit resonator structure and a short-circuit resonator structure. The open-circuit resonator has a signal transmission strip line and a T-shaped strip line. Both ends of the signal transmission strip line are bent toward to opposite ends of the T-shaped strip line respectively, so as to form gaps in the open-circuit resonator. Meanwhile, using the open-circuit resonator structure and the short-circuit resonator structure are coupled under each resonant mode to achieve a bandpass outcome at the band of 60GHz.
