Wireless Local Area Network (WLAN) application nowadays has become more popular, since it allows users to access network services without being tethered to a wired infrastructure. In high performance point to point and point to multipoint application where size, weight, cost, performance, ease of installation are constraints, low profile antenna is very much required. To meet these requirements, microstrip antenna is preferred. In this work two dual bands inverted L and F-shape geometry microstrip antennas using probe feeding operating at 2.45GHz and 5.8 GHz for WLAN application was designed and simulated. The simulation process has been done through EMPIRE software. The properties of antenna such as bandwidth, S parameter, VSWR were investigated. The simulation results show the bandwidth is maximum for dual band F-shape antenna at 5.8 GHz frequency that is 244. The return losses are better for inverted L-shape antenna at 2.45 GHz that is -25.62dB.
