Abstract:
A dielectric filter with an ultra hetero-axial structure is provided with open end-face electrodes. By increasing the capacitance between each open end-face electrode and an external conductor greater than that generated between the open end-face electrodes adjacent to each other, the inductive coupling between two resonators due to neighboring resonator holes is increased.
