Abstract

This letter describes the fabrication and characterization of a fluidic patch antenna operating at theS-band frequency (4GHz). The antenna prototype is composed of a nanocomposite material made bya liquid metal alloy (eutectic gallium indium) blended with single-wall carbon-nanotube (SWNTs).The nanocomposite is then enclosed in a polymeric substrate by employing the UV-assisteddirect-writing technology. The fluidic antennas specimens feature excellent performances, in perfectagreement with simulations, showing an increase in the electrical conductivity and reflectioncoefficient with respect to the SWNTs concentration. The effect of the SWNTs on the long-termstability of antenna's mechanical properties is also demonstrated.
