Flexible Antenna Design for Wearable IoT Devices

The design of antennas for IoT-enabled wearables represents a dynamic intersection of engineering, physics, and user experience. These antennas serve as the gateways through which wearable devices communicate with the digital world, enabling data transmission, reception, and interaction. In wearable IoT-enabled devices frequency bands covered were ISM 2.4-GHz (2.41-2.484 GHz)/5-GHz channels, GPS (1.575 GHz), narrow band in IoT (880-960MHz), GSM (850/900MHz) and the frequency range of 5G bands n77/78/79 is 3.3-5 GHz. In this paper presented an antenna design for 2.4 GHz band wearable IoT-enabled devices. This is a widely used ISM band for wearable devices, along with many wireless technologies. It spans from 2.400 GHz to 2.4835 GHz. The presented antenna is design using Rogers RT5880 flexible subtract with dielectric constant. 2.2 and thickness is 20mil. The size of presented antenna is 55×65×0.508mm3. In this different analysis of antenna with human tissue model is done for on and off body communication and also shown the various bending effect of antenna.
