In recent days, an increase in healthcare activities has prompted the importance of the Wearable Body Area Network (WBAN). In a WBAN, sensors and devices are integrated around the body to measure and track the blood pressure, temperature, oxygen level in blood, pulse rate, etc. WBAN ensures that the data are collected and transmitted without hampering the comfort of the individual. A wearable antenna, which is placed either on the clothes or any other wearable material, is used to connect the WBAN with the LAN for transferring data to the outer world. So far, many researchers have reported wearable antennas that are designed on low-loss engineered material. In our work, we have designed a wearable antenna on highly lossy, day-to-day used jeans. The jeans used here is collected from a local market. It is characterized in the dielectric probe kit using the Open-Ended Coaxial Probe technique. The dielectric constant and loss tangent of jeans are tanδ=0.1152 and r=1.7976, respectively. The antenna is designed to resonate at 2.45 GHz. The gain obtained is 1.8 dBi, and the radiation efficiency is 19%. The gain obtained is sufficient for indoor operation. The antenna is integrated on the human body; thus, the bending effect on the performance of the antenna is also studied. The antenna is optimized for optimal performance.
