Abstract
The goal of this paper is to expand on previously researched Eutectic Gallium-Indium (EGaIn) alloy liquid metal antennas to create an antenna that can change both polarization and frequency to meet the users needs. This concept is described through analytical models of helix antennas, simulations performed in FEKO, and measured results of a proof-of-concept dual frequency L-band GPS-focused hardware model. Although ongoing work is being performed to more efficiently feed this proof-of-concept liquid metal antenna, the overall realized gain of the helix aligned well with theoretical models.
