Title:
IMPEDANCE MATCHING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/148819
Kind Code:
A1
Abstract:
The objective is to provide a miniature impedance matching element wherein unevenness in quality is low and which has high current tolerance. The objective is achieved by an impedance matching element provided with a wiring portion including a wiring-use conductor pattern embedded in an interior or formed upon a surface of a first dielectric material (D1); and inductor units (L4 and L5) including an inductor-use conductor pattern embedded in the interior or formed upon the surface of the first dielectric material (D1); and/or a capacitor portion (C1) including at least one pair of capacitor-use conductor patterns (CC1) and a second dielectric material (D2) which interposes between the pair of capacitor-use conductor patterns and which has a higher dielectric constant than the first dielectric material (D1); wherein the impedance matching element is such that the thicknesses of the wiring-use conductor pattern and the inductor-use conductor pattern are greater than or equal to 20 μm.
