摘要
Based on the principle that one-ended electromagnetic surface wave can drive a plasma antenna, the relation between the effective length of an antenna column and the applied radio frequency （RF） power was studied both theoretically and experimentally. The density dis- tribution along the antenna column as well as the electron temperature in different conditions were investigated. The characteristics of the reception of local frequency modulated （FM） electro- magnetic wave by the plasma antenna were compared with that by a copper antenna with same dimensions. The results show that it is feasible to take plasma antennas as receiving ones.
