Abstract

In this paper, a rectangular microstrip patch antenna (MPA) is designed using different substrate materials for analyzing the performance of the MPA. Alumina (Al2O3), Bakelite, Beryllium oxide (BeO), Gallium Arsenide (GaAs), RT-Duroid and Flame Retardant 4 (FR-4) are the six different substrate used in the design. The size of the rectangular microstrip patch antenna varies according to the dielectric constant of substrate materials used. The operating frequency taken for this analysis is 5.8 GHz. The proposed design provides the study on the performance of rectangular microstrip patch antenna for different substrate materials using the same frequency. This study conveys that which substrate material provides better performance. Moreover, this comparative study conveys that which substrate material provides better performance. The simulation parameters are investigated using HFSS.
