Title:
COMMUNICATION DEVICE FOR HUMAN BODY TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2015/104783
Kind Code:
A1
Abstract:
A communication device includes a substrate, a line, a communication circuit, and a variable capacitance. The substrate includes a ground section and a dielectric section stacked on the ground section. The substrate has a first surface and a second surface on an opposite side of the first surface. The first surface includes the ground section. And the second surface includes the dielectric section. The line is provided on the second surface side and has an inductive reactance. The communication circuit is provided on the second surface and connected to one end of the line and the ground section. The variable capacitance element includes a conductor connected to the other end of the line and is capable of varying a capacitance between the conductor and the ground section when a human body contacts with or comes close to the conductor.
