N2 - This paper proposes a novel fractal antenna with the UWB and miniaturization characteristics. The Mandelbrot fractal geometry with different iterations is used to designed the radiation patch. Also, we use the Mandelbrot fractal to miniaturize the basic structure of circular monopole, where six iterations of the fractal pattern are selected and two modified fractal patterns are rotated and combined to obtain the desired radiating patch structure. In this design, a single wideband from 2.22 to 8.37 GHz is achieved in HFSS simulations, and the fractal antenna has good radiation characteristics and impedance matching in the whole ultra-wideband range. The proposed UWB antenna is designed on an Rogers RO3003 substrate which has a dimension of 25 × 30 × 0.762 mm3 and the size reduction of each element is about 39.1% compared with basic circular radiant patch. Simulated results show that the antenna has a peak realized gain of 5.1 dBi and a high radiation efficiency of greater than 90%.
