摘要：
A novel miniaturized dual-band quarter-mode substrate integrated waveguide (QMSIW) bandpass filter with high selectivity is proposed in this letter. Two passbands are generated by the fundamental mode and the first higher order mode of the spiral-stub-loaded QMSIW resonator, respectively. Miniaturization is achieved by loading stubs and applying quarter-mode cavities. High selectivity can be realized by introducing two transmission zeros (TZs) between the two passbands. One TZ is generated by adding coplanar waveguide coupling between the two resonators, the other TZ is synthesized by coupling between the modes of the resonator. The proposed dual-band filter has the characteristics of miniaturization, high selectivity, and low loss, which is suitable for satellite communication related applications.
