摘要： An ultra high frequency (UHF) radio frequency identification (RFID) tag and a method of manufacturing the tag are provided. The tag includes a substrate, a chip attached to the substrate and having a plurality of bumps for connecting a circuit formed therein with an external, and at least one UHF antenna extended in a longitudinal direction and responding to ultra high frequency transferred from the external, at least one end of the UHF antenna connected to the bump, and one portion of the antenna fixed to the substrate. Also, the method includes a) process of fixing a chip having a plurality of bumps to an upper surface of a substrate, b) process of installing a cutter between the bumps such that a blade portion of the cutter is placed at a certain height from the substrate, and c) process of installing a UHF antenna by lowering the UHF antenna having an extended portion to the cutter, with the antenna being positioned in a direction perpendicular to the blade portion, cutting the extended portion of the antenna by the cutter, and continuously lowering the antenna until a cut end of the antenna is connected to the bump. Since the UHF RFID tag employs a plurality of short UHF antennas instead of a loop-type antenna, the tag is integrated as much as it is required, due to a small volume, and a process of bonding the antenna to a chip is rapidly and easily performed.

摘要： A method of easily and inexpensively manufacturing an antenna for an RFID tag by forming the antenna using magnets of a pattern corresponding to a shape of the antenna is provided. The method includes a) placing a substrate above a level of a fluid containing a conductive substance, b) placing an electrode formed in a shape of an antenna pattern above a surface of the substrate, and applying a current to the electrode, to adhere the conductive substance to a bottom of the substrate in the shape of the antenna pattern by an electromagnetic force, and c) fixing the conductive substance adhered to the bottom of the substrate. Alternatively, the method includes a) placing a thin film above magnets shaped in a desired pattern, b) spraying a certain amount of conductive particles having a desired magnetic property on a surface of the thin film to form the conductive particles in the same pattern as the pattern of the magnet, c) contacting a substrate, on which an adhesive is applied, with the pattern of the conductive particles formed on the thin film, to adhering the conductive particles pattern to the substrate, with the pattern of the conductive particles being maintained, and d) fixing the conductive particles adhered to the adhesive.
