A Design for Wearable Antenna by Using Liquid Metal

A dual-band wearable wrist antenna satisfied with 2.4 GHz and 5.8 GHz frequency suitable for WLAN communications is proposed in this paper, which consisted of PDMS as the substrate material and liquid metal EGaIn as radiation patch. The process of wrist antenna concludes fabrication of PDMS wrist structure with the layered bonding method and injection of EGaIn with vacuum compression method. The interaction between human body model and antenna is also investigated.
