      Radiation characteristics of antenna in weakly ionized dusty plasma environment

      • 摘要: 研究了弱电离尘埃等离子体环境下天线的辐射特性. 通过仿真实验得到了半波偶极子天线与双频微带天线的回波损耗、EH面增益方向图、三维辐射方向图. 结果表明,在弱电离尘埃等离子体环境下,两款天线的谐振频率会产生偏移,其偏移量与环境温度有关,且带宽也会相应地发生变化. 因此,在建立通信系统时,除了要考虑尘埃等离子体的电波衰减影响,天线的回波损耗及谐振点的变化也是需要考虑的因素.

         

        Abstract: The radiation characteristics of antennas in weak ionization dust plasma environment are studied. The return loss, EH gain pattern and 3D radiation pattern of half-wave dipole antenna and dual-frequency microstrip antenna are obtained by simulation experiments. The results show that the resonant frequency of the two antennas will be offset in the weak ionization dust plasma environment, and the offset is related to the ambient temperature, and the bandwidth will also change accordingly. Therefore, when establishing a communication system, in addition to the attenuation effect of the dust plasma wave, the return loss of the antenna and the change of the resonant point also need to be considered.
