Title:
LAMINATION TYPE FILTER AND COMMUNICATION DEVICE USING SAID LAMINATION TYPE FILTER
Document Type and Number:
WIPO Patent Application WO/2020/067405
Kind Code:
A1
Abstract:
A first capacitor is formed that includes one portion of pattern conductors (2) of a plurality of pattern conductors (2). A second capacitor is formed that includes the other portion of pattern conductors (2) of the plurality of pattern conductors (2). An inductor is formed that includes, of the plurality of pattern conductors (2) and a plurality of via conductors (3), the pattern conductors (2) and the via conductors positioned between the first capacitor and the second capacitor. The first capacitor, the second capacitor, and the inductor are connected to an external electrode (4) in parallel with each other. When seen along the lamination direction of a plurality of insulator layers (1), in the short direction of a laminated body (LB), if the width of the laminated body (LB) is W, and of the plurality of pattern conductors (2), the minimum value of the width of the pattern conductor (2) included in the inductor is PW, then 0.5 W < PW < W.
