Process-dependence of inkjet printed folded dipole antenna for 2.45 GHZ RFID tags

• This paper focuses on the process dependence of an inkjet printed folded dipole antenna based on practical parameters in a typical inkjet printing process. We present the effect of width variations and number of overprinting times on the antenna properties such as gain, radiation efficiency and input impedance. Furthermore we investigate the read range degradation of the tag on which the antenna is attached, due to width or thickness variations. In addition, an comparison between an inkjet printed antenna on a regular paper substrate and a copper antenna on Printed Circuit Board (PCB) was made, manifesting the strong competitiveness of the printed silver antenna as a low cost solution.
