摘要

In this article, a series of compact and wideband quarter mode circular cavity(QMCC) substrate integrated waveguide (SIW) bandpass filters (BPFs) based onslotlines perturbation have been proposed. The proposed filters utilize quarter modeSIW cavities to reduce the profile of 75% comparing with the conventional SIWcavities. The C-shaped and E-shaped slotlines etched on the SIW cavities are usedto broaden the bandwidth of the filters and improve the passband selectivity. Boththe slotlines and SIW cavities can be regarded as resonators. In addition, extrametallic via-hole loaded on the SIW cavities is applied to form a four-order widebandbandpass filter with enhanced out-of-band rejection. To verify the principlesmentioned above, the proposed bandpass filters are designed, fabricated, and measuredin a standard printed circuit board (PCB) process. The QMCC SIW filterswith E-shaped slot and metallic via-hole perturbation is measured at a central frequency(CF) of 5.76 GHz with a 3 dB fractional bandwidth (FBW) of 26.4%.Within the passband, the minimum insertion loss (IL) is <1.32 dB. The measuredresults show good agreements with the simulated ones.
