Document Type and Number:
Japanese Patent JP4887813
Kind Code:
B2
Abstract:
To provide an RFID information recording medium capable of extending easily the maximum communication distance, while using an existing IC inlet.
This RFID information recording medium 1 for executing communication using a radio wave is provided with an antenna for receiving the radio wave, a chip connected to the antenna, and a nonexcitation element 4 comprising a conductor, and the antenna and the nonexcitation element 4 are arranged on the substantially same plane. More electric power is thereby taken out from the received radio wave, so as to increase an antenna gain along a direction orthogonal to the plane provided with the antenna.
