Abstract: In this paper a microstrip slot patch antenna is designed for WLAN applications. The antenna is designed to operate at 2.4GHz using the Advanced Digital System(ADS) software. The proposed antenna is designed and fabricated usingFR4 substrate with the design specification dielectric constant of 4.6 and thickness (d) of 3.2mm. The antenna produces gains of 3.75dBiand a directivity of 6.58dBi at 2.4GHz which suitable for WLAN applications.
