Coupling Structures in Combline Resonators
Combline 공진기 내의 결합구조
Abstract
Three types of the coupling structures in combline resonators are presented: magnetic, electric, and mixed coupling structures. The magnetic coupling structure is provided by the window, and the electric coupling is provided by the electric probe. The mixed coupling structure which is the superposition of the magnetic and electric coupling structures, is proposed for the electric coupling in combline resonators with easy tuning capability. The responses of each coupling structure are shown. A 4-pole combline filter is designed and fabricated as an application of those coupling structures, and shows good filter responses.
