摘　　要：借助天线测试系统,实验研究了柱形等离子体天线的阻抗特性和辐射特性。实验结果发现:该柱形等离子体天线与相同构造和尺寸的金属天线相比,具有较好的宽带阻抗特性;柱形等离子体天线的相对增益在50～260MHz频带范围内与金属天线相差不大;等离子体发射天线相对增益略高于等离子体接收天线。An experimental system is established to study the impedance and radiation properties of plasma-column antenna.The results show that the impedance bandwidth of plasma antenna is much wider than that of metal antenna of the same structure.The gains of the two antennas are nearly the same from 50 MHz to 260 MHz.In addition,the relative gain of plasma transmitting antenna is higher than that of plasma receiving antenna.

关 键 词：等离子体 天线 辐射 阻抗 增益
