An inverted T-shaped patch microstrip antenna using electromagnetic band gap( EBG) structure on the ground plane is presented. The measured 10 dB bandwidth for return loss reaches 805 MHz (2. 099~2. 944 GHz) and 831 MHz (4. 568~5. 409 GHz), which covers both the 2. 4 GHz/5. 2 GHz WLAN (Wireless Local Aerea Network) bands. Furthermore, the 3. 1 dBi of relative high gain is achieved. The measured data is in good agreement with the simulated. The study indicates that the proposed antenna can satisfy the WLAN band standards and has a good prospect of application.
