Communication terminal including close-proximity communication coil, power transmission coil, and metal plate

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;
• wherein
• at 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 power transmission coil is electromagnetically coupled with the metal plate;
• a portion of the power transmission 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 second slit portion;
• and
• a coil opening portion of the power transmission coil overlaps with the second slit portion when viewed from a direction perpendicular to the main surface of the metal plate.
