Design and analysis of wearable textile UWB antenna for WBAN communication systems

Abstract

In present scenario, with application-centric approach of all the modern communication devices, integration of electronic gadgets with wearable accessories is in high demand. This research paper presents design and simulation of wearable antenna using flexible textile substrate and analysis of various performance antenna parameters. The design and simulation of proposed jeans substrate-based textile antenna have been performed using CST 2018 Microwave Studio. Main emphasis of the current research work is to demonstrate a small-sized UWB antenna design having overall antenna size 20 mm × 22 mm × 1.07 mm. The resonant frequencies of the designed dual-band antenna are observed to be 4.45 and 8.75 GHz and have a wide fractional bandwidth of 103.5% in the ultra-wide band range. The presented microstrip patch textile antenna is compact, robust and flexible that makes it perfect choice to be utilized as body worn antenna for WBAN communication systems for wireless health monitoring systems.
