英文摘要：

The feasibility of replacing metal antenna by plasma column which is formed a fundamental antenna vibrator is analyzed first. Then according to the approach of integral equation which is appropriable to metal antenna, the input impedance of plasma antenna is calculated and imitated. Furthermore, the evolution of input impedance is studied with varying plasma parameters. The results of numerical analysis and simulation with XFDTD （ a software） show that the input impedance of plasma can be varied with the plasma parameters such as plasma electric density and collision frequency. With the advantages of the property, reconfigurable antenna vibrator can be made from such plasma column.
