摘要：

A compact substrate integrated waveguide (SIW) dual-band bandpass filter (DBSF) using novel quasi-SIW-transmission-line-structure resonators is proposed in this study. This dual-resonance SIW resonator which works in TE100 mode and TE201 mode can be evolved from a conventional SIW-transmission line or a two-conductor transmission line. Multiple signals transmission paths bring extra transmission zeros (TZs) and improve the selectivity and out-band rejection of the DBSF. This filter works at 4.75 GHz/4.82 GHz, 5.38 GHz/5.51 GHz with 3 dB fractional bandwidths of 3.8 and 3.9%, respectively, and has six TZs. The measured results agree with the simulation results well.
