摘要
本文提出了一种利用阶梯式阻抗微带线构造微型带通滤波器的新型结构。在该结构中引入以零相位方式接入的微带抽头,与带集总电容的阶梯式阻抗微带滤波器相配合,通过在通带两侧分别产生两个传输零点,很好地改善了滤波器的带通特性。
A novel structure of stepped impedance resonator microstrip bandpass filter with input and output taps is presented. Two taps for feeding in zero-degree-phase-mode signals are added. Cooperating with stepped impedance resonator microstrip filter which have additional lumped capacitors, the proposed filter improves its performance by adding two transmission zeros at both sides of its pass-band characteristic curve.
