摘要：
An ideal helix plasma antenna operating in the UHF band is studied in the paper. By using numerical method FDTD, the relationship between the radiation characteristic of the plasma antenna and the plasma parameters is revealed. The simulation results indicate that, when the plasma frequency is sufficiently higher (at least ten times) than operating frequency and the collision frequency is correspondingly low, the antenna has the same characteristic with the metal one. Moreover, the similarity level of characteristic is direct proportional to plasma frequency and inverse proportional to collision frequency.
