Abstract: This paper presents the rectangular fractal antennas with triple band characteristics are proposed for Ultra-Wideband (UWB) applications. The patch is a tree-like fractal structure consisting of superposition of several rectangular patches. To improve the impedance matching, a Defected Ground Structure (DGS) is used as a ground plane. Design and study of W slots are used to etch on the patch to analyze the notch bands of UWB antenna. The substrate used for the designed antenna is a low-loss laminate of FR4 with a dielectric constant of 4.4. We optimized several parameters of W slots to get the better notch bands of Wi-Max (3.8 – 4.8 GHz) and WLAN (6.5 – 7.6 GHz). The proposed antenna gives good simulation results in terms of scattering parameters like return loss, VSWR and radiation patterns that claims to be suitable for UWB applications.
