In the article, low cost, RFID antenna is fabricated by gravure printing with PET acting as the substrate. The nanosilver ink with 50% silver content is prepared in the lab and the printing speed is set to 5m/min. After sintering at 150°C for 2min, surface resistance of the antenna reaches to 7.31Ω/sq and thickness of the silver layer is 466nm. Then, the antenna is treated at -40°C for 6h. Interestingly, the resistance of the antenna dropped by 9%, which may due to the limited motivation of PVP chain in relatively low temperature. In order to study its stability, the RFID antenna has been put into the night side, sunny side and room temperature for 30 days. The resistance is nearly the same as its original after 1 month, though some decreasing appeared. The result indicates that the antenna fabricated shows excellent stability and the working temperature can range from -40°C to 150°C.
