Conductive Ink and Applications in Printing Antenna of RFID Tag

摘要

Antenna of RFID tag is used to spread frequency signals and build wireless connection between the tag and reader. High cost, low production speed and environment pollution exist in the traditional methods of manufacturing antenna. In order to overcome the disadvantages above, the method of printing antenna with conductive ink is being widely researched. So, conductive ink gets more and more attention. In order to study the performances of conductive ink better, conduction mechanism of conductive ink are mainly discussed. The requirements of conductive ink to print antenna are described. The present status of conductive ink in printing antenna is introduced, and research directions in future are also predicted.
