Purpose of the Study:
- To determine the dielectric properties of paper substrates for RFID tag printing.
- To measure the conductivity of silver nanoparticle inkjet-printed conductors.
- To compare the performance of inkjet-printed RFID tags with traditional printed circuit board (PCB) tags.
Main Methods:
- Dielectric properties of three paper substrates were measured from X-band to K-band.
- Conductivity of silver nanoparticle ink was measured.
- Electromagnetic (EM) models were developed using measured parameters.
- Inkjet-printed and PCB tags were fabricated and their performance was experimentally evaluated.
Main Results:
- Dielectric properties of paper substrates and conductivity of silver nanoparticle ink were quantified.
- EM simulations were performed using the obtained material parameters.
- Performance comparisons were made between simulated, printed, and PCB tags.
Conclusions:
- Accurate material property characterization is essential for reliable EM simulation of inkjet-printed RFID tags.
- Understanding performance differences between printed and PCB tags informs manufacturing choices for SHM applications.
- This work provides critical data for the development of cost-effective, printed chipless RFID tags.
