  • Contactless communication medium, antenna pattern arrangement medium, communication apparatus, and communication method
    Patent number: 9208427
    Abstract: A contactless communication medium includes: a base material made of an insulating material; an antenna coil portion formed by winding a conductor in a plane on the base material; a capacitor connected to the antenna coil portion; a communication processing section connected to the antenna coil portion and the capacitor to perform a contactless communication process; and a metal pattern having a predetermined area and disposed in a region surrounded by the antenna coil portion, the metal pattern being not electrically connected to the antenna coil portion or the capacitor.
    Type: Grant

  • Non-contact communication device
    Patent number: 8967487
    Abstract: Provided is a non-contact communication device including an antenna configured to transmit data through non-contact communication after load-modulation of an RF signal from a reader/writer (R/W), wherein the antenna includes: a standard coil having an aperture with a predetermined size; and a small coil having an aperture with a size smaller than a size of the standard coil, wherein the standard coil and the small coil are connected in series or in parallel, and the small coil is arranged such that the aperture of the small coil overlaps a winding part of a coil that is an antenna of the R/W when the non-contact communication device is caused to face the R/W by matching a predetermined position of the non-contact communication device with a reference position of the R/W determined in advance as a position with which the predetermined position of the non-contact communication device is to be matched.
