摘要: A novel triple-mode resonator based on the half-mode substrate integrated waveguide (HMSIW) structure is proposed to design ultra-wideband (UWB) filters. The UWB filter topology given by analyzing resonant frequencies of three modes and signs coupling between input/output ports. With synthesis method, a with passband from 3.1-10.6 GHz effectively realized two transmission zeros at upper stopband. To block existing undesired narrowband radio signals in FCC range, notched band can be easily generated controlled loaded stub-capacitor. For demonstration, an tunable 3.7 7.7 compact size designed fabricated. Both simulated measured results indicate that new has properties wide tuning range sharp roll off.
