Abstract
An RFID antenna is fabricated according to varying current density requirements of different regions of the antenna. A method such as computer modeling is used to determine the current densities of the antenna regions. In one aspect of the invention, a conductive material is printed to a substrate at varying thickness according to current density requirements of particular antenna regions. In another aspect of the invention, materials of different conductivity are printed to the substrate according to the current density requirements. A material of higher conductivity is printed at an antenna region that requires high current density, and a material of lower conductivity is printed at antenna region that requires lower current density.
