Abstract
This paper presents the development a wearable RFID application that is flexible, compact, low-cost, and suitable for the human body. The study's main goal is to design, build, and test a small and flexible RFID wristband tag antenna with UHF RFID operating frequency at 910 MHz. The result shows a good radiation pattern and an almost ideal VSWR which 1.09. Thus, a wearable UHF RFID tag antenna is designed with a gain of -11.87 dB for bending analysis. The tag features a meander dipole antenna with two square split-ring resonators (SRR) cells. A meander dipole antenna with two square split-ring resonators (SRR) cells is featured on the tag. It's built on a 0.277mm thick photo paper substrate with a dielectric constant of 3.2 and a loss tangent of 0.05. The proposed antenna is then combined with an RFID tag (NXP SL3S1213 UCODE G2iL chip) with an impedance of 23-j224 to evaluate its performance in terms of reflection coefficient, antenna gain, and maximum reading range. The overall size of the antenna tag dimensions is 117 mm × 26 mm.
