As wearable electronics advances, integrating Radio Frequency Identification (RFID) technology into textiles offers promising applications in smart clothing, healthcare monitoring, and athletic performance tracking. However, traditional RFID antennas are often rigid, costly, and incompatible with fabric, which compromises comfort, washability, and scalability, limiting their suitability for wearable systems. To address this challenge, this study investigates a low-cost, flexible method for producing textile-based RFID antennas using screen printing. A square antenna was fabricated directly onto a polyester textile using screen printing with silver conductive paste. Screen printing was selected for its scalability, rapid production, and compatibility. Compared to knitted and embroidered antennas, this method offers better geometric control and is easier to implement on textiles. The printed antenna conformed to standard RFID design dimensions and was produced in a single print stroke. Following fabrication, the antenna was connected to an Arduino microcontroller and paired with a passive RFID tag for performance testing. The system successfully detected the RFID tag, confirming the antenna’s functionality. Electrical measurements confirmed a sufficiently low resistance, indicating reliable conductivity for RFID communication. While further optimization is needed, these preliminary results demonstrate that screen printing is a viable technique for integrating RFID antennas into textiles. This approach offers a scalable, low-cost pathway to smart garments that are lightweight, comfortable, and suitable for real-world use, particularly in sports performance tracking and health monitoring. Future work will focus on enhancing antenna durability and evaluating long-term performance under, for example, repeated bending, washing, and wear. Acknowledgements The COMET project DiMo-NEXT is funded by the Federal Ministry for Innovation, Mobility and Infrastructure (BMIMI), the Federal Ministry for Economy, Energy and Tourism (BMWET), and the provinces of Salzburg, Upper Austria, and Tyrol within the framework of COMET – Competence Centres for Excellent Technologies.
