This article presents a novel approach in monopole antenna design in combination with fractal shaped patch element and slotted ground plane in a monopole configuration. The most significant feature of the antenna is its almost constant high gain which is maintained at all the frequencies of interest. The structure is easy to fabricate and due to its compactness it can be easily incorporated in portable devices suited for wireless communication purposes. The presented structure shows a wide bandwidth of 3.3 GHz (3.0 GHz to 6.3 GHz), which covers the IEEE 802.11 WLAN bands (5.2 GHz and 5.8 GHz) and WiMAX bands (3.5 GHz and 5.5 GHz). The antenna has gain of 5.01 dBi, 5.07 dBi, 5.09 dBi and 5.11 dBi at frequencies of 3.5 GHz, 5.2 GHz, 5.5 GHz and 5.8 GHz respectively. An average gain of 5.07 dBi realized at the proposed WLAN and WiMAX bands is an added advantage in this regard.
