RFID TAG

摘要

There is provided an RFID tag that has a significantly wide antenna bandwidth and that operates more stably. The RFID tag is characterized by including a loop feeding element formed on a base material; an IC chip that is electrically connected to the loop feeding element and that is laid on the base material; and an artificial medium that includes a dielectric layer having a first surface and a second surface, a first conductive layer laid over the first surface, and a second conductive layer laid over the second surface and on which the base material is stacked, wherein the first surface is placed closer to the loop feeding element than the second surface; and, when viewed from a stack direction in which the loop feeding element is stacked on the artificial medium, the loop feeding element is placed so as to enclose a part of an edge portion of the first conductive layer of the artificial medium.
