Binder-free conductive carbon-based ink is printed on flexible polymeric substrates such as PET and paper as an antenna for wireless devices. Without addition of polymer binder, conductivity of the carbon-based ink can be greatly improved. Owing to the enhance of conductivity, carbon-based ink proposed in this patent can be applied to antenna application, such as RFID, and enormously decreases the antenna cost. Further compression and protective coating will further enhance adhesion of antenna. |
