Plasma antennas have attracted considerable research in recent years due to their numerous distinct advantages over the conventional metal antennas [1-2]. Many numerical techniques have tried to model the characteristics of plasma antennas, including in the finite-difference time-domain (FDTD) method [3-4]. However, these investigations mainly focused on the scope of unmagnetized plasma antennas. This paper has analyzed the radiation properties of a magnetized plasma antenna both in the near-field and far-field using the PLRC-FDTD method, which is of high accuracy and quite suitable for the dispersive medium [5-6]. The parameters of the magnetized plasma antenna investigated here include not only the plasma frequency ω_p, the electron collision frequency v, but also the cyclotron frequency ω_c. The numerical results show that it is feasible to dynamically reconfigurate the radiation performance of the magnetized plasma antenna for radio frequency communication.
