A ferrite-loaded broadband loop antenna having nearly comparable transmitreceive characteristics is disclosed. One or more electrodes are coupled to the material. Connecting electrodes are electrically connected to the electronic component element and a conductive pattern to be used for image recognition is provided on the upper surface of the area for a sealing frame. In the affirmative, a password is transmitted to the station so that the read unit sends it to the object to open the read barrier. The torque isolating shell also contains a top surface which has a counterbore that accommodates a crush ring.
