Embroidered quad-band electro-textile wearable antenna for WBAN applications

The requirement of textile integrated antenna systems has been rapidly growing for wireless body-centric communications. In this paper, an embroidered quad-band jean-based antenna using conductive thread is investigated with dimensions of 50×30×1mm3. An embroidery fabrication method is used in this design for easy integration and for bulk production with digital machines. The Simulations has been done in Ansys HFSS environment and prototype testing using Agilent combinational analyzer. The designed fully textile prototype using an embroidered antenna operates in 3.03-3.76 GHz,5.48-6.24 GHz,7.10-7.40 GHz, and 7.93-8.22 GHz bands. The simulated and prototype measured results show the feasibility of the proposed wearable antenna for body-centric communications in WBAN.
