A microstrip-fed planar monopole antenna consisting of an inverted-L monopole and a square parasitic element extending directly from ground plane to obtain wideband operation covering Bluetooth/ISM, 2.5 GHz WiMAX, 3.5 GHz WiMAX and 5.2/5.8 GHz WLAN bands is presented. The proposed antenna employs a shorted parasitic element to improve the bandwidth. The return loss of the suggested antenna geometry was calculated by a commercial HFSS 9 simulator and the results are compared with measured return loss, which shows a good agreement between them. Details of the proposed antenna designs and experimental results of the constructed prototypes are presented.
