In this paper, a hexagonal fractal antenna is proposed for wireless applications. The basic shape of the fractal antenna is a hexagon which is modified by inserting smaller hexagons along the periphery of the generator structure. The proposed antenna exhibits a bandwidth of 7.5 GHz in the frequency range of 3.3-10.8 GHz. The band notch for WLAN rejection at 5.75 GHz is obtained by etching hair-pin slot in the feed structure of the antenna. The fractional bandwidth of the antenna is 53.33 and 55.62% and the VSWR obtained at the notch frequency of 5.75 GHz is 5.2 which are highly suitable for wireless communication.
Key words: Fractal antenna, Ultra wide-band (UWB), VSWR, notch, hair-pin slot.
