Design and characterisation of a microstrip patch antenna for Wi-Fi

Abstract

In recent years, the inventions in communication systems require the development of low cost, minimal weight, compact and low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort in the design of micro strip patch antennas because of its inherent characteristics that fits the requirements of modern communication devices. This dissertation presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.45GHz and 5 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 16 and MATLAB which will be used to calculate the parameters. The substrate used for the proposed antenna is the flame resistant four (FR-4) with a dielectric constant of 4.3 and a loss tangent of 0.023. The proposed antenna may find applications in wireless local area network (Wi-Fi) and Bluetooth technology.
