A novel flexible ultra-wide band wearable slot antenna with defected ground for WBAN applications

This study introduces the development of a flexible and compact radiator using a jeans material as a substrate for wireless body area network (WBAN) applications. A fabric made of jeans with a thickness of 0.6 mm, a tangent loss (tan δ) of 0.02, and a dielectric constant (εr) of 1.6 is used for designing an element with dimensions of 18.5×27×0.6 mm3. The jeans substrate incorporates a triangular feed structure on top and a defected ground structure (DGS) on its back. This design enables a span ranging from 3.41 to more than 20 GHz, with a magnitude of S11<-10 dB, a peak gain of 4.48 dBi, and a peak efficiency of 97.28%. The system is designed for Ultra-wideband (UWB) integrated with Ku band. The measurement findings are very consistent with the results obtained from the models. The suggested antenna is highly appropriate for WBAN applications because to its thin profile, flexible design, and compatibility with WBAN and UWB technologies..

Methods
The data presented in this manuscript is the simulated using Ansys HFSS and CST microwave studio electromagnetic tools and then simulated antenna design is fabricated and using vector network analyzer, the measured results are obtained. this dataset also mentions various figures that show the antenna modelling and its design in various steps. Using simulation tool, the antenna performance is presented. The fabricated antenna performance is evaluated and then compared with the simulated results and made conclusion using the comparison results.
