Abstract: 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.
