Radiation characteristics of antenna in weakly ionized dusty plasma environment

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.
