N2 - The slot-fed hemispherical dielectric resonator antenna (DRA) with a parasitic rectangular slot in the ground plane is studied in this paper. It is found that the length and position of the parasitic slot can be used to widen the DRA bandwidth or to tune the DRA frequency. The exact DRA Green's function is used in the formulation, and the unknown slot currents are solved using the method of moments. Measurements were carried out to verify the calculations, and good agreement between theory and experiment is obtained. © 2005 IEEE.
