Design of Smart Wearable for Quality Analysis

This study introduces an advanced portable device using reliable wireless technology to establish the communication between people and nearby equipment. Due to modernization, the electronic devices require a compact antenna. The compact size, low cost, and better efficiency is the key requirement of the current research. This study is mainly focused on the ultra-wide band antenna of notched antenna, which is simulated using different substrate mounted on a ground and is generally attached to some part of the ground surface. A rectangular substrate with dimensions 25mm×23mm×1.5mm is inserted within the ground and patch. The dimensions of radiating antenna placed on the substrate is 15mm×15mm×0.035mm and for the Ultra-Wideband (UWB) antenna the resonant frequency is 4.8GHz and 10.3GHz respectively and its fractional bandwidth is 110% in the frequency range of the 3.1GHz to 10.7GHz. The simulation is performed in HFSS 2021. After obtaining all the parameters of the antenna, which is comparatively analyzed by using the different types of the substrate material like FR4, jeans, rubber, Rogers RT 5880 etc. The proposed antenna is useful for the wearable applications generally for the on or off body centric communication.
