Liquid Metal Broadband Monopole for Stretchable Electronics

Abstract

This paper presents a broadband monopole antenna made out of smart materials for stretchable electronics. The antenna consists of a liquid conductor and a thermoplastic - Galinstan (gallium indium and tin) for the radiating element and SEBS (styrene-ethylene-butylene-styrene) for the antenna substrate. The antenna is simulated with a full-wave solver and is compared to measurement. The simulated result is in a good agreement with the measured. The reflection coefficients show broadband characteristics from 1.4 GHz to 6 GHz.
