Investigation on parasitic semiconductor on microstrip patch antenna operate at 2.4 GHz / Murni Kamarudin

The design of a rectangular microstrip patch antenna covered with semiconductor material operating at 2.4 GHz for wi-fi application is presented. This paper investigates the semiconductor effect to microstrip patch antenna based on the variety of thicknesses and type semiconductor. The semiconductor material used in this paper such as GaAs, AlGaAs, InGaAs with having difference permittivity.Permittivity for each semiconductor material is difference will indicates a material can become polarized by imposition of an electric field on an insulator (substrate antenna). The antenna are optimized using Computer Simulation Technology (CST) at 2.4 GHz frequency, the antenna will fabricated on FR4 with relative permittivity of 4.8, the substrate thickness is 1.6mm and the copper thickness is 0.035mm respectively. The results of return loss (Sn) are gathered and compared based on difference semiconductor material and thickness.
