<p>A wireless IC tag to and from which data can be written and read between a writing/reading apparatus by way of wireless communication, wherein a ferroelectric memory using a ferroelectric having a power source unit for receiving a radio wave from outside and for generating an electric current by resonating with the radio wave and an antenna unit for carrying out wireless communication in a predetermined frequency bandwidth, and a UHF band communication antenna chip for receiving a radio wave of a UHF bandwidth are connected to be mounted on a substrate so that communication in a frequency band longer than the UHF band is carried out by the antenna unit of the ferroelectric memory and data is saved in the ferroelectric memory, and at the same time communication in the UHF band is carried out by the UHF band communication antenna chip and the data is saved in the ferroelectric memory.</p> |
