A Biodegradable Textile-based Graphene Antenna for 5G Wearable Applications

This paper presents a textile-based antenna for the currently deployed fifth-generation (5G) wireless bands. The proposed antenna consists of a coplanar-waveguide (CPW)-fed patch with truncated sides and a pair of L-shaped stubs as a part of ground geometry. The antenna has a bandwidth of 3.3-3.8 GHz, a peak gain of 3.17 dBi at 3.7 GHz and an efficiency of 64%. The antenna is designed on denim fabric and offers desired flexibility and ease of integration as a part of a garment, environmentally friendly and biodegradable attributes of graphene due to non-metallic nature, and affordability in terms of manufacturing cost.
