Abstract
In this paper, a high gain rectangular patch antenna is presented for S-band application. The dimensions of rectangular patch antenna are optimized to obtain the desired result and coaxial feed is used to improve the gain and surface wave excitation. The proposed antenna is simulated at resonance frequency of 2.4 GHz. FR4 glass epoxy substrate with thickness of 1.6mm is used in this design. The simulated design exhibits high gain of 6.9dbi and reflection coefficient is below -17db in the entire range of operation and designed antenna can be used for ISM (industrial, scientific and medical) band and WLAN applications. It also exhibits qualities like low profile, low cost, easy fabrication and good isolation. Themicrostrip patch antenna is designed by using Ansoft HFSSV13 simulation software.
