Design and Implementation of Wearable Antenna for Biosignal Monitoring

摘要

This work presents a novel method for designing and fabrication of a wearable antenna for tracking bio-signals of soldiers during military operations. The antenna is incorporated in existing fabric and operates in the widely used ISM Band (2.4 GHz) and uses cotton textile as dielectric substrate, and is thereby flexible, light and rigid enough to be worn on the body of the soldiers to monitor their bio-signals. The simulation of designed antenna shows that it resonates at the operating frequency of 2.48 GHz with a return loss of -30 dB under normal condition and ～23 dB under bent condition, which argues well with the measured results for the design. The fabricated wearable antenna has advantages such as low fabrication cost, high flexibility and virtually maintenance free design.
