Design and implementation of discontinuities in Microwave filter design

The systematic design and implementation of microwave circuits play a crucial role in the microwave industry. The traditional method of design is based on trial-and-error methods, leading to approximation-based structures. This research work primarily focused on the analysis, design, and implementation of discontinuities in slotted resonator structures, achieving empirical modelling of the coupled resonator structure for the implementation of bandstop filter design. This work leads to a generic systematic design of a microwave structure, like a filter, based on the developer specification. The systematic design and implementation of a band-stop filter using coupled resonator theory for a fractional bandwidth of less than 20% is discussed. Also, a study on the modelling of discontinuity-based structures with elliptical modelling techniques is performed.
