An article provided with a device for wireless communications, and the device

Document Type and Number:

Japanese Patent JP6115679

Kind Code:

B2

Abstract:

A wireless communication device includes an antenna resonance circuit and a wireless IC element. The antenna resonance circuit includes a loop-shaped antenna that performs wireless communication by generating a magnetic field and series inductors connected in series to the loop-shaped antenna. The antenna resonance circuit has a resonant frequency corresponding to a carrier frequency. The wireless IC element is connected to the antenna resonance circuit and processes transmission and reception signals. An inductance value of the series inductors is larger than an inductance value of the loop-shaped antenna, and the series inductors are covered with a magnetic material.
