The rapid development of Internet of Things (IoT) has driven the need of flexible, lightweight, and wearable antennas that can adapt the contours of human body. This research aims to develop textile-based antennas that can be integrated into cloth, intended for radiation emission measurement and IoT application. In this research, two fabrication techniques are proposed, namely embroidery and coating techniques. A square patch antenna is fabricated using the embroidery technique, while both square patch and disc-shaped array antennas are realized using the coating technique. The developed antennas operate at ISM band frequencies of 2.4 GHz and 5.8 GHz for IoT application. The design, simulation, fabrication, measurement, and implementation of textile antennas are considering both flat antennas and those subjected to curvature effects. The measurement results indicate that the textile antenna fabricated using the embroidery technique has good flexibility but slightly lower radiation performance compared to the one realized by coating technique. Furthermore, the textile antenna produced using the embroidery technique demonstrates comparable performance to the conventional antennas in terms of data rate testing, with the additional advantages on its flexibility and user comfort. In addition, this research also compares the implementation results with widely used conventional antennas and other related studies. The proposed textile antennas not only meet the required technical requirements but also expand the potential of IoT application, particularly in the development of more user-friendly and comfortable smart devices. These results indicate that the proposed textile antennas based on embroidery and coating techniques can be effective and efficient alternatives to the conventional antennas for radiation emission measurement and IoT application.
