RFID label and RFID tag
An RFID label includes: a substrate; a dipole antenna formed of a metal foil so as to have a predetermined antenna length and a predetermined antenna width, the dipole antenna being arranged on a surface of the substrate; an IC chip connected to the dipole antenna; and a separator temporarily adhered to an adhesive agent overlaid on the surface of the substrate on which the dipole antenna is arranged, wherein a tear off line cuts through the substrate and the dipole antenna, in at least a part of the dipole antenna, so as to extend along an antenna length direction and so as to be superimposed with the part of the dipole antenna.
1. An RFID label having a part separable by a tear off line, the RFID label comprising:
a substrate;
a dipole antenna formed of a metal foil so as to have a predetermined antenna length and a predetermined antenna width, the dipole antenna being arranged on a surface of the substrate; and
an IC chip connected to the dipole antenna, wherein
the dipole antenna is provided with:
an IC-chip connecting portion to which the IC chip is connected;
a loop portion having the IC-chip connecting portion;
a meander extending from the loop portion in a direction intersecting with a direction in which the tear off line extends; and
a part formed to have an antenna width wider than a width of other parts of the dipole antenna, said part extending along the direction in which the tear off line extends, and
the tear off line extends through the substrate and the dipole antenna so as to extend along and through said part of the dipole antenna.
2. The RFID label according to claim 1 , wherein
a holding substrate configured to hold the substrate is overlaid on a back surface of the substrate.
3. An RFID tag having a part separable by a tear off line, the RFID tag comprising:
a substrate;
a dipole antenna formed of a metal foil so as to have a predetermined antenna length and a predetermined antenna width, the dipole antenna being arranged on a surface of the substrate; and
an IC chip connected to the dipole antenna, wherein
the dipole antenna is provided with:
an IC-chip connecting portion to which the IC chip is connected;
a loop portion having the IC-chip connecting portion;
a meander extending from the loop portion in a direction intersecting with a direction in which the tear off line extends; and
a part formed to have an antenna width wider than a width of other parts of the dipole antenna, said part extending along the direction in which the tear off line extends, and
the tear off line extends through the substrate and the dipole antenna so as to extend along and through said part of the dipole antenna.
4. The RFID tag according to claim 3 , wherein
a holding substrate configured to hold the substrate is overlaid on a back surface of the substrate.
