A High-Fidelity All-Textile UWB Antenna with Low Back Radiation for Off-Body WBAN Applications

A novel all-textile UWB antenna with full-ground plane and high on-body fidelity is presented in this work. Due to the combined requirements of backward radiation reduction in WBANs and highfidelity prerequisite for UWB pulse transmission/reception, a multilayered structure is implemented. The structure consists of two patches and a ground plane implemented on two layers of 2-mm-thick substrate. The full ground plane on the lower layer shields users against on-body radiation. Numerical and experimental evaluations both in free space and on human body prove the antenna operation within the FCC UWB bandwidth of 3.1–10.6 GHz. Its high-measured on-body system fidelity values of between 95% and 97% at a distance of 1 m show that the textile UWB antenna is suitable for body-worn UWB impulse radio communication.
