- Abstract
In this paper, a novel coupling structure is presented, which could easily change the coupling nature between combline resonator (CR) and dielectric resonator (DR). This coupling structure is based on electric field orientation of DR operating in TE01δ-mode, through altering the direction of copper sheet in the DR, the excited orientation of electric field would be changed along with the coupling nature between two resonators. To prove this method, two filters using cascaded triplet (CT) coupling relation are designed, fabricated and measured, showing the controllable coupling nature between CR and DR. Measured results confirmed the predicted performance.
