Özet
In this study, the far-field characteristics of a plasma dielectric resonator antenna are investigated. The internal structure of the antenna is filled with a plasma material. Surface currents are obtained in an imaginary closed area formed at a certain point outside the plasma antenna. Then, the near field-far field transformation is performed with the FFT method using the surface currents. The field distributions in the far field of the plasma antenna have been evaluated using three-dimensional FDTD. The system has shown to work in multiband with wider bandwidths.
