Spectral anomalies due to coupling-induced frequency shifts in dielectric coupled-resonator filters

Spectral anomalies due to coupling-induced frequency shifts in dielectric coupled-resonator filters

Coupling-induced frequency shift is identified as a source of spectral response degradation in higher-order coupled-resonator add/drop filters that must be compensated in design. The theoretical basis and experimental verification are presented, and generic solutions proposed.
