In this paper, an aperture coupled dual band microstrip antenna for application in Worldwide Interoperability for Microwave Access (WiMax) and Wireless Local Area Network (WLAN) is presented. The dual band is operable at resonant frequencies 3.6GHz and 5.2GHz. In the design the slits have been cut at the boundaries of the rectangular shaped patch, so the resulting configuration is E-shaped patch antenna. The proposed antenna achieves an impedance bandwidth of 50.2MHz and 139MHz at frequencies 3.6GHz and 5.2GHz respectively.
