Microstrip-based all-textile unidirectional UWB antenna with full ground plane

Abstract

A design overview for a microstrip antenna topology operating within the full UWB band is described. Existing broadbanding concepts have been creatively combined throughout this design to enable the UWB behavior, while simultaneously keeping the full ground plane intact. This is crucial in maintaining worn antenna performance. It successfully reduces any on-body performance degradation, resulting in a very robust structure. A detailed numerical and experimental evaluation of the antenna is performed in free space and on body.
