【 摘 要 】

A novel quarter mode substrate integrated waveguide (QMSIW) resonator is proposed, based on which a plane cascade QMSIW tunable filter is designed. Miniaturization of the filter is achieved, whose area is only 0.51λg × 0.34λg. The filter works at 1.2 GHz with the tunable range of 31.6% and the fabricated insertion loss less than 1.9 dB and return loss greater than 15 dB, respectively.
