ABSTRAKT

The topical problem of studying basic properties and searching methods for improving the plasma radiator array, which is similar to the array of metal or dielectric antennas, has been considered. The emitters based on cold plasma are of interest for scientists due to the prospects for developing effective multi-beam scanning selective plasma reconfigurable systems or emitter plasma arrays. The paper studies the main electrodynamics parameters of the emitter plasma arrays in the microwave range, which characterize it both as a load for the generator (receiver) of electromagnetic signals and as a transmitter of electromagnetic energy in respect to its directional pattern and the main parameters of radiation. Distortions of impedances of emitter plasma arrays and directional pattern deformations are investigated as the beam of directional pattern is scanning. For comparison, similar studies have been carried out for the same design and configuration of the radiation pattern of metal antennas. The researches have been performed by simulating emitter plasma arrays and calculating their parameters in the software FEKO by mean of the integral equation method and the method of moments for the linear emitter plasma array consisting of four emitters in the form of the loop dielectric tubes filled with cold plasma under a low pressure. The obtained results can be used for calculations and design of emitter plasma arrays.
