Patent ID: 8680950

Claim:
A multilayer bandpass filter comprising: a plurality of dielectric layers; a ground electrode; a plurality of LC parallel resonator circuits, each including: a capacitor electrode; an inductor electrode; and first and second via electrodes each passing through corresponding ones of the plurality of dielectric layers; wherein the capacitor electrode faces the ground electrode to define a capacitor; the inductor electrode includes one end portion that is connected to the capacitor electrode by the first via electrode and another end portion that is connected to the ground electrode by the second via electrode, and the first and second via electrodes and the inductor electrode define an inductor; a via coupling electrode arranged to directly connect only one of the first and second via electrodes in the inductor in one of the plurality of LC parallel resonator circuits and one of the first and second via electrodes in the inductor in another one of the plurality of LC parallel resonator circuits which is adjacent to the one of the plurality of LC parallel resonator circuits and does not directly connect any other ones of the first and second via electrodes in the inductor of any other of the plurality of LC parallel resonator circuits.
