We outline the possibilities of 3D direct write dispensing and brush-painting in the manufacturing of copper UHF RFID tags on textile and cardboard materials and present considerations regarding the process parameters to achieve high-performance tags when the copper antenna is deposited directly on these rough and porous materials. Our measurement results confirm that the additively-manufactured copper RFID tags on environmental-friendly substrates achieve high performance with the attainable theoretical read ranges of 3.5-to-8.5 meters in air.
