Abstract

A class of planar bandpass filters (BPFs) using dual/triple-mode substrate integrated waveguide (SIW) resonator and ground coplanar waveguides (GCPWs) are proposed according to miniaturization and high selectivity. The quasi-elliptic

asymmetric and non-transmission zero (TZ) response dual-mode SIW filters can be realized by changing resonance frequencies of TE

102

and TE

201

and the external couplings. Two GCPWs of the same size are etched on SIW cavity top metal plane;and the TE

102

201

and two GCPWs in a single SIW cavity are combined to construct the diversifi

ed response fourth-order filters. On the basis of asymmetric and non-TZ response

the fundamental mode TE

101

can be shifted to the passband to form a fifth-order filter with wider bandwidth. The designed BPFs were fabricated and measured;and the simulated and measured results agree with each other

demonstrating the feasibility of using hybrid dual/triple-mode SIW and CPWs in a single cavity to design BPFs.
