English title

This theoretical study examines the characteristics of a surface wave driven plasma monopole antenna using finite difference time domain method (FDTD) as well as commercial full wave simulator. The results show that the full wave simulator can be considered as an acceptable tool in simulation of a plasma antenna. Input impedance, radiation pattern, gain, efficiency and radar cross section of plasma antenna at plasma and collision frequency values are presented here using FDTD numerical method. Comparison between the achieved results with a conventional metallic antenna shows that the plasma antenna is an acceptable radiation tool in the first resonant region and can provide a dynamically reconfigurable antenna.
