ANTENNA FOR RADIO FREQUENCY IDENTIFICATION

摘要

PURPOSE: An RFID(Radio Frequency Identification) antenna is provided to prevent the lowering of a recognition ratio of information received from a reader by vertically forming a coil unit on a substrate with a winding shape. CONSTITUTION: An RFID antenna includes a substrate(100), a first coil unit(110a), and a second coil unit(110b). The substrate is made of a soft magnetic material. A first coil unit is formed on an upper side of the substrate with a spiral shape. One side(112) of the first coil unit is connected to an IC chip of an RFID tag. The other of the coil unit is electrically connected to the second coil unit. The second coil unit is vertically formed with the winding shape.
