| Abstract: | The physical model of the plasma antenna with plasma-insulating tube-vacuum is established. Then the new dispersion relation is derived. Through the geometric interpretation, a new algorithm with high precision and fast convergence is presented. Simulation results verify the correctness and effectiveness of the conclusion. The dispersion relation of cylindrical plasma antenna is studied when the electron density decreases according to the linear law. And the radiation pattern is given. The results have important reference value in analysis and design of the plasma antenna. |
