- 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.
