ABSTRACT
Several recent technologies are emerging that integrate the wearable system with antenna technology. The wearable antennas embedded into textiles are the most promising and fully integrative ones in the field of wireless body area networks (WBAN). In this chapter, a fully textile wearable antenna operating at 2.4 GHz with Minkowski fractal design is presented. The antenna is fabricated using a pure silver conductive thread on the polyester substrate using the embroidery technique. A 3D full-wave electromagnetic simulation tool is used to simulate the design. The antenna is placed onto the human body to obtain a specific absorption rate (SAR) result. Simulation results are demonstrated using different antenna parameters like S11 return loss, VSWR, Gain, and Directivity. Results showcase the multiband antenna performance for various applications with four resonant frequencies 2.68, 4.06, 4.32, and 4.46 GHz. The SAR value for the simulated embroidered textile fractal antenna is 1.32 W/kg when placed along with the realistic human male torso model in HFSS.
