Abstract
In this research manuscript, the author proposes an innovative solution for monitoring and preliminary detection of bone health with the use of a newly designed Hexagonal Ring Wearable Textile Antenna (HRWTA) using polyester material. The HRWTA is designed and fabricated using polyester conductive electro-textile as radiating fabric and polyester fabric as substrate having dielectric constant of 1.44 with loss tangent of 0.01. The motivation behind this work stems from the increasing number of osteoporosis cases around the world has led to a greater need for new, non-invasive ways to keep track of bone health. Leveraging advancements in microwave technology and antenna design, this study introduces a novel approach by drawing parallels between hexagonal ring and annular ring microstrip antennas, resulting in a precise empirical formula for resonance frequency calculation [9]. Rigorous validation through simulations and experiments showcases the antenna's accuracy in assessing bone health parameters. HRWTA, born from this formula, offers a discreet and affordable means for continuous bone health monitoring, holding significant promise for early intervention and improved healthcare outcomes in the face of the growing osteoporosis challenge. The return loss bandwidth of HRWTA is 350 MHz (3.39 GHz-3.74 GHz, 10%). Also, it has a peak gain of 2.5 dB at 3.5 GHz. Hence, HRWTA is suitable for wireless body area network (WBAN) as it has good radiation characteristics.
