Abstract

Abstract:

Plasma antenna with cylindrical configuration is analyzed by a straightforward application of the finite-difference time-domain (FD-TD) method. The computed results of the antenna, including radiation pattern, input impedance and radiation efficiency, are shown compared with metallic antenna. The result shows that these quantities vary with the parameters of plasma including plasma electric density and collision frequency. Plasma antenna can replace metallic antenna with the advantages of reconfigurability and invisibility. It is meaningful and instructional for the optimization of the plasma antenna design.

Key words: FDTD, plasma antenna, radiation pattern, input impedance, radiation Efficiency
