Graphene-based flexible wearable THz antenna for WBAN application

In the THz spectrum, Graphene exhibits immense potential for the development of ultra-compact antennas due to its distinctive tunability feature. This paper presents a flexible wearable THz antenna using graphene nanomaterial for wireless body area network (WBAN) applications. The proposed antenna consists of a rectangular graphene patch placed over the polyamide substrate. The antenna design is optimized at 3 THz for on-body wearable applications. The body and bending effects of the proposed antenna are analyzed in this work. Specifically, the body effects, including the skin, fat, and muscle, with air gaps of different values, are investigated. The results show that the proposed graphene THz antenna holds great promise for WBAN applications.
