Abstract
A highly reliable RFID tag is provided that is lighter and smaller and has a desired communication distance, and that can be applied to deformable articles. The RFID tag includes a first end of a first power feeding coil that is connected to a first input and output terminal of an RFIC element, a second end of the first power feeding coil that is connected to one end of a second power feeding coil, and the other end of the second power feeding coil is connected to a second input and output terminal of the RFIC element. Moreover, the RFID tag has a spring-shaped antenna that has a first region with magnetic field coupling of the first power feeding coil, and a second region with magnetic field coupling of the second power feeding coil. The first region and the second region are continuous via a region having an inductance component.
