Patent ID: 8531253

Claim:
A series LC resonator with a 3D structure comprising: a dielectric substrate having a predetermined permittivity; pattern portions of a first conductive layer for the series LC resonator, which are formed in a predetermined pattern on portions of a surface of the substrate; and a pattern portion of a second conductive layer of a lower electrode part of a capacitor for the series LC resonator, which is formed on a portion of the other surface of the substrate, wherein the pattern portions of the first conductive layer have pattern portions of the first conductive layer representing an inductor for the series LC resonator and a pattern portion of the first conductive layer representing an upper electrode part of the capacitor for the series LC resonator, respectively, wherein the pattern portion of the first conductive layer representing the upper electrode part of the capacitor includes a first rectangular pattern portion of which one of first sides facing each other has a rectangular notch formed by removing a rectangular portion from the one of the first sides, wherein the pattern portions of the first conductive layer representing the inductor include: a second rectangular pattern portion disposed inside the notch to allow three sides to be disposed at a same interval from corresponding ones of three sides of the notch; a third pattern portion which is formed integrally with the first pattern portion and extends from a portion of the other one of the first sides of the first pattern portion in a shape of a straight line having a predetermined width and length; and a fourth pattern portion which is formed integrally with the second rectangular pattern portion and extends from a portion of the remaining side of the second rectangular pattern portion in a shape of a straight line having a predetermined width and length, and wherein the second rectangular pattern portion is electrically connected to the pattern portion of the second conductive layer via a conductive layer inside a through-hole of the substrate.
