Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-contact communication device comprising an antenna configured to transmit data to a reader/writer (R/W) through non-contact communication after load-modulation of an RF signal received from the R/W, wherein the antenna includes: a standard coil having an aperture with a predetermined size; and a plurality of small coils, each of the plurality of small coils having an aperture with a size smaller than the predetermined size of the aperture of the sta…
