摘要:

采用自行设计的高频发射机(10～20MHz),对环天线和线天线进行了激发实验.结果表明:直接耦合环形天线在射频(RF)功率大于10 W时,可激发天线中的气体形成等离子体,射频功率降到5 W时,等离子体仍可维持.对于线天线,直接耦合时射频功率达到20W时可激发产生等离子体;电容耦合时射频功率达到30 W时可激发产生等离子体,射频功率降至10 W时,两种耦合方式均可维持等离子体.用环形金属天线作接收天线,测量了环状和线状等离子体天线在直接耦合方式和电容耦合方式时的发射性能,结果表明:等离子体天线与普通金属天线一样具有辐射性能,接收到的信号电平随发射信号电平增大而增大,呈近似线性关系.因此,等离子体天线可以用于高频无线电通信.

Abstract:

Using self-designed high-frequency transmitter (10~20MHz), the ring antenna and line antenna were excitation experiments. The results show that when the direct coupling loop antenna is greater than 10 W, the gas in the antenna can be excited to form plasma, and the plasma can still be maintained when the RF power drops to 5 W. For line antennas, plasma can be excited when the RF power reaches 20W when directly coupled; When the RF power reaches 30 W during capacitive coupling, plasma can be excited to be generated, and when the RF power drops to 10 W, both coupling methods can maintain plasma. Using the ring metal antenna as the receiving antenna, the emission performance of ring and linear plasma antennas in direct coupling mode and capacitive coupling mode was measured, and the results showed that the plasma antenna had the same radiation performance as ordinary metal antenna, and the received signal level increased with the increase of the transmitted signal level, showing an approximate linear relationship. Therefore, plasma antennas can be used for high-frequency radio communications.
