Abstract

See full text

A variable frequency antenna including a dielectric element and an enclosure within the dielectric element. An electrically conductive liquid metal is disposed in the enclosure. The liquid metal is a eutectic mix of about 68.5% gallium, about 21.5% indium, and about 10% tin. Changing the temperature of the liquid metal causes the liquid metal to change volume within the enclosure, thereby changing an RF frequency characteristic of the liquid metal.
