Microwave characterization of graphite and intercalated graphite as an antenna element

Abstract

Intercalated graphite (IG) possesses uniquely tunable DC conductivity using electrochemically intercalated sulfuric acid as the intercalant, giving it the potential to add significant functionality to antenna elements and other microwave circuit elements, but its microwave and antenna properties have not previously been measured. In this research, graphite and (IG) are characterized for their microwave properties to be used as antenna elements, and impedance and other changes due to intercalation are analyzed. In addition to measuring RF properties, both materials are used as antenna elements, and their radiation characteristics are measured.
