Patent ID: 7196626

Claim:
A RFID tag comprising: a substrate, comprised of flexible materials, including Polyimide or polyester organic materials, or inflexible materials, including porcelain, glass and PCB, or resin for processing of PCB, including epoxy resin or glass fiber; an antenna, adhered to a surface of the substrate, and comprised of conducting materials, including Cu-or Al-inclusive metallic conductor or microwave carbon fiber material, said antenna further comprising a conductor plane and a conductor pressing section, the pressing section serving as a reference unit for a tag signal; and a wireless telecommunication IC, adhered to the surface of the substrate and electrically linked between the conductor plane and the conductor pressing section of the antenna, an area of the conductor plane of the antenna is bigger than that of the conductor pressing section, thus yielding an image effect for the antenna, resulting in reduced length, area and input impedance of the antenna.
