Abstract or Description:

This study explores wearable antenna designs developed based on the merits of graphene as a flexible, conductive fibre. First, graphene oxide (GO) liquid crystals (LCs) at GO concentration of 10 mg/mL-1 with dominant nematic phase formation are prepared. Then, GOLCs are wet-spun by designed spinning line and these continuous fibres are further reduced by NaBH4 to gain electrical conductivity. These yarns are intertwined with conventional yarns onto conductive ground substrates. Challenges related to the fabrication process of graphene based textile antennas for near-field communication is discussed. The proposed design is compared to patch antennas with the use of embroidering techniques involving silver yarns and inkjet-printing of conductive inks. This study is concerned to assess the use of graphene fibres as the conductor in textile antennas, and overcome the problem of the high surface resistance, and consequently the low efficiency in antenna gain.
