In this paper, we present a K-band substrate-integrated waveguide resonator bandpass filter structure. The filter uses an antisymmetric mode of the resonator for the first time. A design method for the external coupling structure of the resonator utilizing the antisymmetric mode is described. In addition, a methodology for suppressing neighboring resonances(More)
This paper presents a positive-to-zero continuously tunable interresonator coupling structure for postloaded substrate-integrated cavity resonators. Two interresonator coupling structures with the opposite coupling signs were integrated. The continuously tunable negative microstrip line coupling structure can generate large enough coupling to cancel out the(More)
This paper presents a new class of filter responses called pseudo-Butterworth filter response. A detailed mathematical analysis on the pseudo-Butterworth response has been carried out. In addition, the comparison between the typical complete Butterworth response and the new pseudo-Butterworth response is provided. The theory for the pseudo-Butterworth(More)
