摘要
A compact substrate integrated waveguide (KW) dual-mode dual-band bandpass filter (DM-DBBPF) is presented based on two-layer stacked configuration. TEloi and TE201 modes in SIW rectangular cavities are exploited to construct the respective first and second passbands, and the two bandwidths could also be realized over a wide range of ratio by applying the design parameters ratio technique. Thanks to multilayered structure, the footprint of the filter has been reduced about 33% compared to our previous similar work. A prototype operating at 12 and 17 GHz with the fractional bandwidth ratio of 0.77 is designed, fabricated, and tested for demonstration, showing good agreements between the simulated and measured results.
