In this project, a flexible thin film and environment friendly graphene-conductive polymer composite antenna was developed on a low cost plastic film for wearable application at 2.4 GHz. Nowadays, extreme research growths on graphene conductive polymer materials has been explored due to mechanical flexibility, high efficiency, low cost and electric field-controllable properties. These special properties made this material as a promising conductor for biomedical application and RF wireless application. Within this context, exploitation of ink-jet printing graphene together with conductive polymer, poly (3, 4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) were developed in this project and printed on plastic film substrate with dielectric permittivity, εr of 2.3. In addition, parametric studies of the number of printing layer towards antenna resistivity performance are also performed. The final antenna printing produces conformability to the surfaces, ability of design versatility, and low manufacturing costs with compact size of 0.16λ0 × 0.42λ0 or 9.88cm2 and wide bandwidth of 84.17% which serve the requirements of wearable antenna application at 2.4GHz.
