A RFID SYSTEM WITH ASYMETRIC HELICAL ANTENNA FOR RFID

摘要

PURPOSE: A radio frequency identification(RFID) system containing an asymmetric helical RFID antenna is provided to operate under the stacking environment of metal plates and to be recognized under the stacking environment. CONSTITUTION: An RFID chip(210) is formed on the first side of a first substrate. A first wire is formed on the first lateral side of the first substrate based on the RFID chip. A second wire is formed on the second lateral side of the substrate which is symmetric to the first lateral side based on the RFID chip. The first wire includes electrodes. A first electrode is in connection with the RFID chip. A second electrode is in connection with the first electrode and is formed at the second side. A third electrode is formed at the first side and is connection with the second electrode.
