Analysis And Development of Ultrawide Band Flexible Wearable Textile Antenna for Wireless Body Area Network

Abstract

In this study an ultra-wide band (UWB) microstrip ring slotted patch antenna with enhanced bandwidth is proposed to achieve multiband operation. The proposed antenna with dimensions of 45mm x 60mm x 1mm is fabricated on flexible textile substrate (Jeans, $\varepsilon\mathrm{r}=1.68,\tan\delta=0.01)$. The developed antenna resonates in Ultra-wide band between 2.3 GHz to 12 GHz with operating frequencies at 2.45Ghz,5.45Ghz and 6.5Ghz. The simulations and measurements of the proposed antenna has been done using Ansys HFSS software. The optimal return loss (S11) and radiation pattern features has successfully returned by the UWB antenna making it advantageous for new promising medical applications. The results of the antenna modelling have been shown to be appropriate for UWB WBAN applications in the field of medical science since there has been a significant growth of WBAN for the purpose of enhancement of medical applications
