ORTHOGONAL RFID TAG DIPOLE FOR STEEL COIL

摘要

PURPOSE: A present invention is provided to manufacture an orthogonal RFID tag dipole for a steel coil having high performance and manageability by reducing a height of a tag adhered to a steel coil using an electromagnetic periodic boundary face due to an oxide layer formed between steel sheets of a steel coil and an electromagnetic coupling property of an orthogonal RFID tag dipole. CONSTITUTION: An orthogonal RFID tag dipole for a steel coil is adhered to the side of a steel coil and has the current component of an orthogonal direction to a direction in which a conductor of a steel coil is placed.
