Dual-Channel Communication of Column Plasma Antenna Excited by a Surface Wave-Actualization and Simulation of Radiation Pattern
2015
Along with the introduction of the concept of dual-channel communication, we utilized the finite-difference time-domain (FDTD) method to simulate and measure the radiation pattern under certain plasma densities and plasma collision frequencies. Results show that under certain settings, the radiation pattern of a plasma antenna resembles that of a metallic antenna. In contrast to a metallic antenna, a plasma antenna possesses other functionalities, such as dynamic reconfiguration and digital controllability. The data from simulation are similar to the measurement results, indicating that column plasma antenna can realize dual-channel communication. This work confirms the viability of realizing dual-channel communication by column plasma antenna, which adds a new but promising method for modern intelligent communication.
