Design, simulation and implementation of a pre-ionized coupled plasma antenna at VHF band

Plasma Antenna is a new and efficient technology that has been introduced in recent years. In this area, previous works has generally focused more on experimental results. In this paper, a basic theory of the plasma material is introduced. Then a design of a Plasma antenna based on these theories is presented at VHF band. The simulation is performed by using the practical software CST Microwave Studio Suite 2011. In order to validate the simulation results of the designed Plasma antenna, an implementation of proposed antenna is performed. Results of experimental measurement of implemented antenna show a good agreement with the simulation results which has been obtained based on proposed design procedure of Plasma antenna.
