利用根据单极表面波驱动等离子体天线原理建立的等离子体天线,通过实验和理论方法验证了单极表面波等离子体天线的等离子体长度与所加射频功率的关系,主要研究了不同射频功率相同充气气压和射频功率相同不同充气气压下的等离子体密度及其沿等离子体天线的分布和电子温度沿天线的变化,并将等离子天线和相同尺寸的铜天线接收本地调频波段电磁波的特性进行了对比,证实了等离子体天线作为接收天线是可行的。
The relationship between the plasma length and the applied RF power of the unipolar SAW plasma antenna was verified by experiments and theoretical methods using a plasma antenna based on the principle of a monopole surface-wave driven plasma antenna. The effects of different RF power levels The plasma density and its distribution along the plasma antenna and the electron temperature along the antenna at the same inflation pressure and RF power at different inflation pressures are compared with those of the local FM band received by the plasma antenna and the same size copper antenna , Confirmed that the plasma antenna as a receiving antenna is feasible.
