摘要：
An ultra miniature modified quarter mode substrate Integrated waveguide (QMSIW) resonator is proposed. The dominant resonant mode of the proposed resonator is TE101 mode. The area of the modified QMSIW resonator is reduced by nearly 97.3% compared with the conventional fullmode SIW resonator. With the new coupling structures, the miniaturized resonator can be properly arranged in the filter design to minimize the footprint of the circuit. A novel filter using compact modified QMSIW cavity is designed, the proposed compact filter is fabricated to prove the predicted results in experiment, and good agreement is obtained.
