AN ELECTROMAGNETIC ABSORBER SHEET, AN RFID ANTENNA AND TAG WITH THE ABSORBER AND A METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: An electromagnetic wave absorber, an antenna for an RFID tag, the RFID tag, and a manufacturing method thereof are provided to secure the stable operation of the RFID tag regardless of attached materials by absorbing the electromagnetic waves reflected from the attached materials. CONSTITUTION: An antenna for an RFID tag includes an electromagnetic wave absorber(100), a dielectric layer(120a), and a metal layer(130). The dielectric layer is formed on the electromagnetic wave absorber. The metal layer is formed on the dielectric layer. The electromagnetic wave absorber is made of a mixture of powder with high permeability, urethane binder, and silicon disperser. The powder with high permeability is sendust powder or permalloy powder.
