The Design of Bandpass Filters with Resonators Changed Coupling Nodal Point

공진기의 결합 노드 위치가 바뀐 대역통과 여파기의 설계

In this thesis, approximated design formulas for bandpass filters using changed coupling nodal point resonators are derived. The formulas take into account the arbitrary coupling node of lumped and distributed resonators. The advantage of this filter is its abilities to change freely the coupling structure between two resonators. Using the design formulas two filters were designed and simulated. Their responses verified the formulas.
