Kind Code:
B2
Abstract:
Provided is an identification body that allows an ID to be identified using an antenna, wherein the identification body can be easily achieved without requiring the use of special equipment as a configuration capable of identifying a desired ID. The present invention has a ground pattern 20 and a plurality of antennas 11a-11l which are provided facing the ground pattern 20 with a base substrate 10 therebetween, and which generate a resonance peak by facing the ground pattern 20. The ground pattern 20 has a shape covering the antennas 11a-11l when viewed in a plan view, and the resonance frequencies and polarization directions of the antennas 11a-11l differ from each other such that it is possible to identify the ID. On at least a portion of at least one antenna selected according to the ID among the antennas 11a-11l, additional patterns 31a-31f are disposed facing the ground pattern 20 from the opposite side as the ground pattern 20 through a protective layer 30a.
