In this study, a novel fractal antenna with semicircular structure is proposed including the single band-notched property. Proposed antenna has been fed with microstrip line. Measurements and simulated results demonstrate that the prototype antenna has an acceptable return loss level, good radiation pattern characteristics, and gain flatness within desired bandwidth. Except for the notched band, the impedance bandwidth of 3-11 GHz with VSWR<;2 is obtained for the proposed antenna. This band stop property between 7.3-8.3 GHz for C band communication is obtained by embedding a pair of C-slots on the partial ground plane. The antenna is simulated using HFSS and CST high frequency simulators.
