摘要: In this paper, a class of triple-band bandpass filters with two transmission poles in each passband is proposed using three pairs degenerate modes ring resonator. order to provide physical insight into the resonance movements, equivalent lumped circuits are firstly developed, where first and third passbands can be distinctly tracked as function port separation angle. Under choice 135° 45° separations along ring, four open-circuited stubs attached symmetrically they treated perturbation elements split second-order modes, resulting two-pole second passband. To verify design concept, filter prototypes on single microstrip resonator finally designed, fabricated, measured. The achieved all passbands, demonstrated verified simulated measured results.
