| 摘 要： | 用环形荧光灯制作了两幅等离子体天线,等离子体激励源分别为220 V交流电压和射频信号.测量了两种等离子体天线的电压驻波比和远区辐射场强,并与周长相同的方框金属天线的特性进行了对比.结果表明,等离子体天线的增益较金属天线平均低5 dB左右;在试验频率低端,220 V电源预激励方式下等离子体天线增益比RF直接激励要高2～4 dB,随着频率增加,两者增益差变小.

| Abstract: | The radiation characteristics of plasma antenna were studied.The plasma antenna was an annular fluorescent lamp which could be driven by either 220V AC or RF signal.A metallic antenna was used as a reference.The distant field strength and VSWR of these three antennas were measured.The relative gains of these antennas were obtained.The gain of a plasma antenna is found to be less than that of a metallic one at an average of 5 dB;At the lower end of experiment frequency band,the gain of a 220V AC pre-driven p... |
