Microwave engineering filter synthesis technique for coupled ridge resonator filters

Microwave Resonator Filters for Advanced Wireless Systems

To my mother Kil Jung Lee and my father Seung Joo Lee ii ACKNOWLEDGEMENTS Getting Ph.D. was certainly a family endeavor, and my family has endured much sacrifice for the sake of my education. First I would like to thank my parents to whom my debt is simply infinite. I could not have accomplished what I did without their boundless love, sacrifice, support, and encouragement. My gratitude to my p...

Cross-Coupled Microstrip Hairpin-Resonator Filters

A new class of cross-coupled planar microwave filters using microstrip hairpin resonators is introduced. The realization of both the canonical and the cascaded quadruplet (CQ) filters is feasible. Coupling characteristics of four basic coupling structures encountered in this class of filters are investigated in the light of full-wave electromagnetic (EM) simulations. A four-pole cross-coupled f...

Sensitivity Analysis of Coupled Resonator Filters

Expressions for the sensitivity of coupled resonator filters with respect to the entries of the coupling matrix and the resistive terminations are presented. It is shown that the sensitivities of the network are all determined from a single analysis at a given frequency. The approach allows the elimination of the potentially time-consuming Monte Carlo analysis, which is used in tolerance analys...

Vertically Coupled Microring Resonator Filter for Integrated Add/Drop Node

The add/drop wavelength filter is an essential component in the new-generation photonic network. Microring resonator filters using high index contrast (HIC) optical waveguides are recently attracting attention as add/drop filters owing to their compactness, functionality such as dispersion compensation, and ease of filter synthesis. In particular, the vertically coupled microring resonator (VCM...
