The Application of Plasma Columns to Radiofrequency Antennas

Martin, Noel Maxwell; Borg, Gerard; Harris, Jeffrey; Miljak, D

Description

Plasma offers a promising alternative to metal for a wide variety of radiofrequency antenna applications. In this letter we report measurements of efficiencies up to 50% and radiation patterns for plasma column antenna elements. It is demonstrated that the current distribution along the antenna can be controlled by the plasma density. Plasma columns can be used instead of metal elements in communications antennas.
