A cylinder plasma antenna coated with a dielectric tube is analyzed by using the finite-difference time-domain (FDTD) method. The influences of operating frequency as well as permittivity of the dielectric tube on the radiation pattern of the antenna are investigated. Numerical results indicate that the radiation efficiency of the antenna is a function of the dielectric constant of the outside tube...
To analyze a dielectric medium encapsulation, round cylinder monopole plasma antenna which is more practicable and applicable, the finite-difference time-domain (FDTD) method is implemented. Influences of operating frequency and dielectric tube permittivity on the far-field antenna radiation intensity are investigated and evaluated. Numerical results indicate that the radiated power plays as a function...
