Abstract
A novel fractal triangular monopole antenna with truncated and notched ground for the ultra-wideband (UWB) application is presented and studied in this paper. The proposed antenna is designed based on the fractal theory. By inserting three small triangles and three thin slots central symmetrily in the radiation patch, smaller antenna size and more resonant frequencies in the required frequency range are obtained. The antenna has been simulated, fabricated and measured. It is shown that high performance of the designed-antenna is obtained and the Voltage Standing Wave Ratio (VSWR) requirement of less than 2.0 in the frequency band from 2.6 GHz to 14.26 GHz is well satisfied.
