filter design using ring resonators
Dear all:
Recently I read something talking about ring resonator filter design. One typical design flow is outlined as follows:
1. Characterize single unit ring resonator to get its Q
2. Extract coupling coefficients for different coupling schems(electric coupling, magnetic coupling, mixed coupling) to generate the design chart.
3. Based on the design chart of Q and coupling coefficients and make use of the traditional LPF design topologies to synthesize the physical parameters of the filter (layout design).
However, I really have no idea on how the Q and coupling coefficients of the ring resonators(especially the split-ring resonators) can be obtained using EM solvers. If you have the design experience or example project in any of the popular EM solvers such as ADS, HFSS, Designer... Kindly share with me your design knowledge.
Thanks in advance!
Best regards,
