A fully printed passive chipless RFID tag for low-cost mass production

Abstract

In this paper a 3 bit chipless RFID tag able to be printed using mass production techniques is introduced. The structure proposed is based on dipole like structures and three of such dipoles conforms a tag. Several chipless RFID tag prototypes were fabricated on PET substrate and measured within the frequency band from 2 GHz to 5 GHz. In contrast to the already reported printed tags where inkjet printing is used, the proposed tag is fabricated using screen printing techniques which enable fast mass production of tags in a very short time with thick conductive tracks of ~10 um. A good agreement between simulation and measurement was obtained and a reading distance up to 1 m is obtained with a transmission power of 3 dBm. The obtained results confirm the use of low cost printed tags for mass market applications.
