In the present paper, a simple and compact a coplanar waveguide (CPW)-Fed hexagonal antenna has been presented. The proposed antenna is composed of a new fractal shaped slot with a hexagonal patch fed. The total size of the presented antenna is 14.5×16.5 mm 2 , which is designed on Rogers RO4350B substrate and having dielectric constant ε r =3.66, a thickness of h=1.524 and loss tangent of 0.004. The impedance bandwidth, defined by -10 dB reflection coefficient. Hence, the simulated results get a proper agreement with an impedance bandwidth of 2.98 GHz to 11.4 GHz. The investigated antenna is suitable for UWB applications. The design validation of the fractal antenna has been achieved by using CST Microwave studio.
