Abstract
This letter presents a cross-coupled SIW filter with a quasi-elliptic response and improved stopband suppression. For cross-coupled SIW filters, suppressing spurious modes often requires rearranging feeding ports, but this rearrangement tends to increase port-to-port crosstalk and limit achievable out-of-band rejection. To address this inherent issue, we keep port positions unchanged and change the port configuration from conventional microstrip lines to an opposite-face GCPW feeding structure. The input and output ports are placed on opposite metal layers, with their ground planes separated by the dielectric substrate. Simulation results show that the port-to-port crosstalk is reduced from -25 to -40 dB to below -100 dB. Measured results show that the proposed filter maintains a similar stopband width as the previous design, while the suppression of the first spurious passband is improved by about 20 dB, reaching better than -50 dB. The improvement is achieved without hybrid structures or extra fabrication steps.
