本文提出了一种新型的微带四分之一波长阶梯阻抗谐振器（SIR）滤波器。两个耦合的SIR之间的导电引脚和开放间隙共同用于产生混合耦合，并且可以通过调节差距之间的间距和导电引脚的位置来分别控制电耦合和磁耦合。基于该结构，设计并制作了一个二阶滤波器和一个三阶滤波器。测量和模拟数据之间的良好协议。
This letter proposes a new type of microstrip quarter-wavelength stepped-impedance resonator (SIR) filter with controllable mixed electric and magnetic coupling. A conducting pin and an open gap between two coupled SIRs are jointly used to create the mixed coupling, and the electric and magnetic coupling can be separately controlled by adjusting the spacing between the gap and the position of the conducting pin. Based on the proposed structure, a second-order filter and a third-order filter are designed and fabricated. Good agreement between the measured and simulated data is obtained.
