Booster antenna, communication IC unit with booster antenna, and communication IC unit with booster antenna with conductor

摘要

PROBLEM TO BE SOLVED: To provide a booster antenna that exhibits high communication performance when attached to a conductor, a booster antenna-mounted communication IC unit, and a conductor-mounted booster antenna-mounted communication IC unit. A booster antenna 1 according to the present invention includes an upper surface side conductor 21 attached to an upper surface side of a base material 10, a lower surface side conductor 22 attached to a lower surface side of the base material, and an upper surface attached to the inside or side surface of the base material. The coil 20 of less than one turn formed by the connecting conductor 23 that electrically connects the end portion of the side conductor and the end portion of the lower surface side conductor, and the antenna-mounted communication IC unit 50 on the upper surface side of the substrate. And an installation unit 30 for installing the device. When the lower surface side conductor and the conductor are electrically contact-connected, the conductor 100 functions as an antenna.
