Antenna design considerations for far field and near field wireless body-centric systems

In this paper we analyze the design and realization of wearable and implantable antennas meant for wireless body-centric systems. Studied wearable antennas exploit electro-textiles, including embroidered textiles and conductive fabrics, for the light-weight and transparent integration with daily clothing. We also present mm-sized implantable loop antennas that are capable of providing electromagnetic power to implant devices from an external on-body loop antenna through near field inductive link.
