A parametric study on three different high dielectric substrate materials for antenna miniaturization is conducted in this paper. The antenna substrates of three different dielectric materials in 2 GHz frequency ranges from 7.5 GHz to 9.5 GHz are investigated. Rectangular microstrip antenna on Aluminium oxide, Rogers RT Duroid 6010 and Silicon substrate is designed at the three resonant frequencies of 8.95 GHz, 8.79 GHz and 8.15 GHz respectively. The antenna is designed and analyzed by using three dimensional full-wave electromagnetic field simulators. The performances of the proposed antenna are analyzed using finite element method formulation within the volumetric region. The overall result shows that, aluminium oxide material substrate performs better in terms of bandwidth, gain and radiation characteristics compare to other two substrate materials.
