A compact triple-band monopole antenna with two different slots for WLAN and WiMAX applications is proposed and experimentally studied. The proposed antenna with a size of 30mm×25mm×1mm is excited by a 50Ω microstrip feed line. The designed antenna obtains three frequency bands through loading an inverted E-shaped slot and an inverted C-shaped slot which incise the surface current and change the path of the current on the rectangle patch. The obtained results show that the designed antenna has impedance bandwidths of 2.4 GHz, 5.8 GHz for WLAN and 3.5 GHz for WiMAX. The return loss, radiation patterns and peak antenna gains are presented using computer simulations and measurements.
