A novel compact chipless RFID tag and near-field reader

A novel compact design of a fully printable chipless RFID tag and two near-field reading techniques for the designed tag are presented in this paper. The tag is made of two multiple slot-loaded rectangular patches. Slots with adjacent frequencies are placed alternately into two patches to reduce the mutual coupling between the slot resonators. The tag measurements are done for both proximity reading and slot card reading techniques. This single sided compact tag has higher data capacity and lower cost compared to the existing printable chipless tags. It can be incorporated in paper or plastic-based items such as ID cards, tickets and banknotes as an enhancement in security in a user friendly way.
