Abstract
Provided are a resonator having a good Q value and a filter using the resonator. The resonator has: a via electrode portion formed inside a dielectric substrate; a plurality of shielding conductors formed on the dielectric substrate to surround the via electrode portion; a first strip line which is connected to one end of the via electrode portion in the dielectric substrate and faces a first shielding conductor among the plurality of shielding conductors; and a second strip line which is connected to the other end of the via electrode portion in the dielectric substrate and faces a second shielding conductor among the plurality of shielding conductors.

A resonator comprising:
- a via electrode portion formed inside a dielectric substrate;
- a plurality of shielding conductors formed in the dielectric substrate so as to surround the via electrode portion;
- a first strip line which is connected to one end of the via electrode portion and faces a first shielding conductor among the plurality of shielding conductors, inside the dielectric substrate;
- and
- a second strip line which is connected to another end of the via electrode portion and faces a second shielding conductor among the plurality of shielding conductors, inside the dielectric substrate,
- wherein the via electrode portion configures a λ/2 resonator in conjunction with the first strip line and the second strip line.
A filter comprising
- a resonator,
- wherein the resonator comprises
