Communication terminal including close-proximity communication coil, power transmission coil, and metal plate
First Claim
1. A communication terminal comprising:
- a close-proximity communication coil configured to be used in a close-proximity communication system;
a power transmission coil configured to be used in a contactless power transmission system; and
a metal plate;
whereinat least a portion of the metal plate is disposed between the close-proximity communication coil and the power transmission coil when viewed from a direction perpendicular or substantially perpendicular to a main surface of the metal plate;
the close-proximity communication coil and the power transmission coil are disposed in non-overlapping locations when viewed from a direction perpendicular or substantially perpendicular to the main surface of the metal plate;
the close-proximity communication coil is electromagnetically coupled with the metal plate;
a portion of the close-proximity communication coil overlaps with the metal plate when viewed from a direction perpendicular or substantially perpendicular to the main surface of the metal plate;
the metal plate includes a first slit portion; and
a coil opening portion of the close-proximity communication coil overlaps with the first slit portion when viewed from a direction perpendicular or substantially perpendicular to the main surface of the metal plate.

Abstract
A communication terminal includes a close-proximity communication coil, a power transmission coil, and a metal plate. The close-proximity communication coil is configured to be used in a close-proximity communication system. The power transmission coil is configured to be used in a contactless power transmission system. At least a portion of the metal plate is disposed between the close-proximity communication coil and the power transmission coil. The close-proximity communication coil and the power transmission coil are disposed in non-overlapping locations when viewed from a direction perpendicular or substantially perpendicular to a main surface of the metal plate. At least one of the close-proximity communication coil and the power transmission coil electromagnetically couples with the metal plate.
