This study pioneers a textile-based antenna designed specifically for wireless body communication, drawing inspiration from a square-shaped structure while integrating a partial ground element into its design. The antenna, compact at 30×30×1 mm3 , is meticulously crafted on flexible jean fabric chosen for its exceptional flexibility. Utilizing adhesive conductive copper and silver tape, the radiating elements and grounds achieve the necessary conductivity. Operating seamlessly across 3.75, 5.7 and 7 GHz on the body and ISM band applications, this antenna is meticulously engineered for applications centred around the human body. Rigorous assessments of its wearability involve systematic bending tests at varying vertical and horizontal angles, which remarkably showcase minimal variation in resonating frequencies despite these manoeuvres. Further validation through on-body testing, where the prototype is placed directly onto the subjects' skin, confirms the antenna's effectiveness in facilitating seamless wireless communication on the body. This comprehensive evaluation highlights its potential as a reliable solution for body-centric wireless applications, emphasizing its structural resilience and functional efficiency in real-world scenarios.
