In this research, a plasma column with a circular cross section magnetized by a DC-axial magnetic field is investigated as a plasma antenna. The radar cross-section and the scattering pattern of radio waves landing to the antenna are studied. The present plasma antenna, in addition to advantages such as lightness, less thermal noise at satellite frequencies, etc., compared to metal antennas, due to its simple structure and ease of rearrangement by various characteristics such as the intensity of the applied DC magnetic field. The current distribution, gas pressure, and electrical power applied to the gas, which changes the plasma density and its cyclotron frequency, are highly adjustable for new operating frequencies. Such characteristics lead to controllability of the radar cross section and the scattering pattern of the antenna. In this paper, we investigate the effect of plasma frequency and cyclotron frequency of the plasma antenna on the scattering of radio waves with different incident angles and frequencies.
