| Summary: | In this paper, an investigation on the methods of excitation and realization of reconfigurable and tunable plasma antennas is presented. Plasma columns operating as antennas are usually excited by a surface-wave technique. Concerning the drawbacks of the conventional surface-wave launchers for the plasma antennas, a modified excitation mechanism is proposed here for applying the signal and excitation waves at a single point along the plasma column. Based on the surface-wave-excited plasma elements, frequency tunable and reconfigurable plasma antennas are analyzed and developed. Good agreement between the simulation and measurement results of the implemented prototypes validates the reconfiguration technique. © 2022 Warsaw University of Technology. |
