并具有较好的天线性能。

Abstract

A system for the fabrication of RFID(Radio Frequency Identification) tag antenna was setup based on a digital drop-on-demand technology. Firstly

the conductive ink was jetted on the polyethylene terephthalate (PET) substrate with a hydrophobic thin film to form the designed antenna pattern. Then the conductive pattern was sintered to form the RFID tag antenna in an oven. The influences of the system parameters on the generation of droplets and the fabrication parameters on the formation of the conductive line were researched. The conductive line with a width of 100 m

a thickness of 2.8 m and the resistivity of 5.2 cm was obtained

and its resistance was almost proportional to the length. Furthermore

a folded dipole antenna was designed

simulated and fabricated

and the performance of the antenna was measured. The results show that the resonant frequency

bandwidth and the S

parameters of the antenna fabricated are in agreement with the simulation results. The experimental results indicate that the fabrication of the RFID tag antenna based on the drop-on-demand technology has advantages in simple system construction

low cost

accurate droplet ejection and a flexible antenna pattern. Moreover

the folded dipole antenna is characterized by size controllability

high conductivity

good resistance uniformity and good antenna performance.
