Title:

ELECTROMAGNETIC RESONANCE COUPLER AND GATE DRIVE CIRCUIT USING SAME, AND SIGNAL TRANSMISSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/179985

Kind Code:

A1

Abstract:

An electromagnetic resonance coupler (100) comprises: a first transmission line (300) on the top surface of a dielectric layer (112); and a second transmission line (400) on the rear surface of a dielectric layer (113). The first transmission line (300) has resonance wires (301, 302) and input/output wires (303, 304). The second transmission line (400) has resonance wires (401, 402) and input/output wires (403, 404). Cover grounds (501, 502) which are separated from each other are provided on the top surface of the dielectric layer (113) or the rear surface of the dielectric layer (112). The resonance wire (301) and the cover ground (501) are connected via a connection part (503), and the resonance wire (402) and the cover ground (502) are connected via a connection part (504).
