Reconfiguration methods of radiation pattern in bipolar-excited plasma antenna system are
studied in this paper. The reconfiguration model of bipolar-excited plasma antenna is analyzed by using
Boltzmann equation, BGK collision model and related theory of antenna, etc. The effects of plasma
parameters on the radiation pattern are simulated by CST software. Through related experiments,
the validity of reconfiguration model is testified. Results obtained indicate that the model has good
precisions and can be used to calculate and analyze the bipolar-excited plasma antenna.
Keywords: Plasma antenna, bipolar-excited, radiation pattern, reconfigurable characteristics.
