This paper presents an ultra-wideband antenna using graphene as a conductive patch. In order to provide flexibility, the cotton fabric is used as a substrate. The proposed antenna covers a bandwidth of 2–8 GHz. Simulated antenna efficiency is approximately 60% in overall bandwidth. The attractive features of conformity, lower design complexity, and fabrication ease as well as integration of an environment friendly and low cost graphene have suggested the proposed antenna well-suited for body-centric, biomedical and wearable applications.
