A novel rectangle tree fractal antenna (RTFA) for ultra-wideband (UWB) application with dual band notch characteristics is proposed. The radiating path is the tree fractal structure which is formed by the superposition of a number of rectangular patches, and multi-frequency resonance characteristics are obtained by only increasing the tree fractal iterations. UWB operation (3.1–10.6 GHz) is achieved by using defected ground structure (DGS) on the ground plane to improve the impedance characteristics between adjacent resonant frequencies. The dual notch bands characteristics are realized by three U-slots on the tree fractal path and effectively suppress the interferences of WiMAX and WLAN. The measurement and simulation results have an acceptable agreement, and indicate that the antenna is suitable for UWB applications.
