Abstract
An RFID tag is provided that includes a base material that includes a first and second surfaces, a coil conductor that includes first and second spiral conductors provided on the first and second surfaces of the base material, respectively, an RFIC chip provided on the base material such that the RFIC chip is positioned in an opening of the coil conductor in plan view of the base material, and first and second connection conductors provided on the first and second surfaces of the base material, respectively. The first and second connection conductors electrically connect first and second spiral conductors and the RFIC chip. Moreover, the first connection conductor and the second connection conductor at least partially overlap each other in the plan view of the base material.
Claims8
An RFID tag comprising:
- a base material that includes a first surface and a second surface opposite to the first surface;
- a coil conductor that includes a first spiral conductor on the first surface of the base material, a second spiral conductor on the second surface of the base material, and an interlayer connection conductor that extends through the base material and electrically connecting the first spiral conductor to the second spiral conductor;
- an RFIC chip on the base material and positioned in an opening of the coil conductor in a plan view of the base material, the RFIC chip including a first terminal and a second terminal;
- a first land conductor on the base material and that overlaps the first terminal of the RFIC chip in the plan view, and that is electrically connected to the first terminal;
- a second land conductor on the base material and that overlaps the second terminal of the RFIC chip in the plan view, and that is electrically connected to the second terminal;
- a first connection conductor on the first surface of the base material and that electrically connects the first spiral conductor to the first land conductor;
- a second connection conductor on the second surface of the base material and that electrically connects the second spiral conductor to the second land conductor;
- and
- a land support conductor on the second surface of the base material and that overlaps in the plan view with at least a part of the first land conductor, at least a part of the second land conductor, at least a part of the first terminal, and at least a part of the second terminal, and that supports the first and second land conductors,
- wherein the first connection conductor and the second connection conductor at least partially overlap each other in the plan view of the base material.
