WIRELESS TAG READING/WRITING APPARATUS, COMMUNICATION METHOD FOR THE WIRELESS TAG READING/WRITING APPARATUS AND WIRELESS TAG RELATING TO THE COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To provide a wireless tag reading/writing apparatus which can suppress radiation of unnecessary radio wave when reading and writing a wireless tag, a communication method for the wireless tag reading/writing apparatus, and a wireless tag relating to the communication method. SOLUTION: A terminated antenna, which is an antenna being terminated at ends, is provided, and the terminated antenna is electromagnetically connected with an antenna of a wireless tag for communication. Thus, remaining power or redundant power is transferred to the terminated antenna and is transformed to thermal energy at the ends. According to an embodiment, a communication antenna for example is faced, in a non-contact manner, to a part or all of a closed plane or open plane formed by a wireless tag antenna, and is electromagnetically connected with the wireless tag antenna, while the terminated antenna is faced, in a non-contact manner, to a part or all of the closed plane or open plane formed by the wireless tag antenna and is electromagnetically connected with the wireless tag antenna.
