CPW-Fed Microstrip Patch Antenna for WLAN Application at Resonant Frequency 2.3 GHz

Abstract

In recent years, microstrip antennas have much more attention due to their attractive features. The increase in demands of high data rate transfer through wireless link, small size antennas used in various purposes. This paper presents, the design and simulation of a coplanar waveguide fed (CPW) microstrip patch antenna at resonant frequency 2.3 GHz that's used for WLAN applications. The patch elements have been placed on the FR-4 epoxy substrate with relative dielectric constant 4.4 at the height of 1.6mm. Simulated results are obtained by using Ansoft HFSS 11 software, which is a full wave electromagnetic field simulator for arbitrary 3D volumetric passive device modeling that takes advantage of the familiar Microsoft Windows graphical user interface. The maximum gain have been achieved by the proposed patch antenna is 9.9 dB at 2.3 GHz band.
