Abstract In this article, a dumbbell shape microstrip patch antenna has presented mainly used for WLAN wireless applications. The simulated result shows that dual bandwidth of 49.07 and 9.47% are obtained covering the frequency range from 1.63 to 2.69 GHz and 3.42 to 3.76 GHz. The characteristics of the designed structure are investigated by using MoM based on IE3d. In the end, an extensive analysis of the return loss, radiation pattern and gain of the proposed antenna has been studied.
