Wearable antenna for bio signal monitoring applications using ISM band

This work presents a simple approach to design a wearable antenna for smart clothing in the ISM or Bluetooth frequency. These smart clothing can be used in designing wearable systems which monitor vital parameters like Bio-Signals of Patients or Soldiers. The microstrip based wearable antenna is simulated using HFSS software and tested after fabrication. This work measures the radiation power levels within a distance of 1m using Antenna Transceiver kits. A current of 120µA was transmitted. Consequently the received power was 85 µA, an efficiency of 70.08%. The final fabricated antenna has an overall dimension of 70mm*70mm. Since it is a wearable antenna, the human body is used as ground plane, making this antenna easy to fabricate and integrate the same effectively into existing fabric materials.
