Abstract
An electronic tag capable of coupling to metal can be attached to the metallic surface of a product, and includes a substrate, a radiation body arranged on a surface of the substrate, a grounding body and a reference line. The grounding body is also arranged on the aforementioned surface and electrically connects to the radiation body. The reference line is arranged on the aforementioned surface and in the grounding body. While such electronic tag is attached to the metallic surface of a product, a portion of the grounding body, which is opposite to the radiation body, contacts with such metallic surface, so that the signal reading distance of such electronic tag can be broadened and extended in virtue of coupling such grounding body with such metallic surface to cause the grounding area to be enlarged. The extent of such contact shall not extend beyond such reference line.
