In this paper, the TE01δ mode and the two degenerate HEH11 modes of traditional high dielectric cylinder resonator are gathered in frequency by grooving the puck in four directions, resulting in a hybrid triple mode resonator with high Q factor. A compact and low loss one-cavity triple-mode filter is then designed with such a resonator. Good features like low loss, sharp rejection and compact size are demonstrated by the measured results.

Abstract
In this paper, the TE01δ mode and the two degenerate HEH11 modes of traditional high dielectric cylinder resonator are gathered in frequency by grooving the puck in four directions, resulting in a hybrid triple mode resonator with high Q factor. A compact and low loss one-cavity triple-mode filter is then designed with such a resonator. Good features like low loss, sharp rejection and compact size are demonstrated by the measured results.File in questo prodotto:
