Polarization Reconfigurbale Antenna with Liquid Metal

Abstract

In this paper, we present a polarization reconfigurable liquid dielectric resonator antenna (DRA) incorporating liquid metal. For the liquid dielectric solution, we use ethyl acetate and for the liquid metal solution, an alloy called Galinstan was used. Before introduction of the liquid metal electric field within the DRA was orientated along the Y-axis. Then by injecting the liquid metal into the liquid dielectric, the electric field rotated 45 degrees. Consequently, polarization reconfiguration was achieved. All of the results presented in this paper were obtained through computer simulation in HFSS.
