Abstract

The paper presents the effect of relative permeability and relative permittivity on the behavior of a miniaturized antenna. The proposed design is combination of hemi-spherical antenna cavity and a hemi-spherical Dielectric Resonator substance; hence this radiating structure is called as hemi-spherical dielectric resonator antenna (HSDRA). Using the DRA, a volumetric source improves the radiation power factor of the radiating slot. [1] The antenna is designed and simulated on HFSS to effectively observe its far-field and near field radiation pattern and different characteristic parameters of antenna system such as gain, VSWR, return loss. The radiation patterns and fields including different characteristics are studied at 3. 75 GHz.
