摘要： With the RFID comprising a transmitting and receiving antenna (18), a detecting block (4) formed in the circumference of the antenna, and an electronic component (17) connected to the antenna and detecting block to detect breakdown of the detecting block, illegal use can be prevented, matching between the tag antenna and IC chip (17) can also be attained with inclusion of the detecting means, and higher radiation and receiving characteristics of antenna can also be obtained without deterioration of antenna gain. Moreover, the RFID is very effective for keeping security because illegal use of the RFID tag through re-adhesion thereof to an item can be prevented.

摘要： An RFID tag which has improved radiation / reception characteristics when used in proximity to the human body, and has an antenna which, when stacked with a 13 MHz band RFID tag, does not have an effect on the loop antenna of that tag. An RFID tag assembly comprises a first RFID tag having a coiled loop antenna and a second RFID tag superposed on the first RFID tag, the second RFID tag comprising an antenna formed by a metal member which covers at least a portion of a surface of a dielectric substrate, an electronic part mounted on the metal member, and a member which is provided with the overlapped coiled loop antenna of the first RFID tag housed in the end thereof so as to cover a portion of the antenna formed by the metal member.
