Theory, measurements, and prototypes of plasma antennas

Plasma antennas have more degrees of freedom then metal antennas making their applications have enormous possibilities. Plasma antennas use partially or fully ionized gas as the conducting medium instead of metal to create an antenna. The advantages of plasma antennas are that they are highly reconfigurable and can be turned on and off. Alexeff and Anderson and [1]–[2] Anderson and Alexeff [3] have done theory, experiments, and have built prototype plasma antennas. Anderson [4] wrote a comprehensive book on plasma antennas. Plasmas are a type of metamaterial. [5].
