Numerical investigation into the performance of two reconfigurable gaseous plasma antennas

Plasma antennas constitute a promising alternative to conventional metallic antennas for applications in which reconfigurability with respect to some property is desired. The latter feature can be achieved by tuning the plasma discharge parameters. We use a full-wave numerical tool, ADAMANT (Advanced coDe for Anisotropic Media and ANTennas), based on integral equations, to assess the role played by plasma discharge parameters in shaping the radiation pattern, which is mainly determined by the plasma current distribution. Numerical results for different discharge parameters show that the antenna radiation efficiency can be controlled by adjusting plasma density and magneto-static field.
