Electromagnetic properties of materials used for paper printed RFID tag antennas

The paper presents the results of experimental investigation into electromagnetic properties of key materials used to fabricate paper printed RFID tag antennas, i.e. paper substrates and conductive paste. The low and high frequency conductivity of silver-loaded paste is investigated under specific parameters of the printing process. Electrical parameters of different corrugated board types and solid paper are also investigated. The results shown in this work can serve as reference data for designing RFID tag antennas.
