Development of Miniature Wearable Ultra-Wideband Antenna Using Qualified Analysis of Different Substrate Material for BCC

Abstract

In this paper we introduced an advance portable device using reliable wireless technology to trigger the communication between people and its nearby equipment's. Due to modernization now a days these electronic devices require the compatible miniature antenna. The compact size, low cost, better efficiency is the key requirement of the current research. This research work basically focused on the ultra-w notched type ultra-wide band antenna and is simulated using different substrate mounted on a ground which is generally 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 which is placed on the substrate is 15mm×15mm×0.035mm for the Ultra-Wideband (UWB) antenna. The resonant frequency is 4.8GHz and 10.3GHz and its fractional bandwidth is 110% in the frequency range of the 3.1GHz to 10.7GHz. The simulation performed in HFSS 2021. All the parameters of the antenna are comparatively analyzed using the different types of the substrate materials like FR4, jeans, rubber, Rogers RT 5880 etc. and we have improved gain, SAR, efficiency parameters of an antenna. The proposed an antenna is applicable for on and off body centric communication.
