    Abstract: An anti-metal radio frequency identification (RFID) tag and a manufacturing method thereof are described. The anti-metal RFID tag includes a substrate having a first surface and a second surface on an opposite side thereof; a planar integral antenna formed on the first surface of the substrate; a RFID transceiver chip (i.e., RFID chip) disposed on the surface of the substrate and coupled to a signal feed point of the planar integral antenna. The flexible planar integral antenna and substrate are folded and then fixed by a fixing mechanism to form an anti-metal RFID tag with a feed-in structure, a RFID transceiver chip, and a radiator on one side, and a ground plane on the opposite side. A spacer is further sandwiched in the center of the folded structure, which is helpful for improving the antenna gain of the anti-metal RFID tag.
