A novel wideband fractal monopole antenna with a semi-elliptical ground plane is presented. In this letter, by inserting a fractal shape in
the conventional circular ring, much wider impedance bandwidth and new resonances will be generated. By only increasing the fractal
iteration, new bandwidth is attained. The designed antenna has a compact size of 15×20×1 mm3and operates over the frequency band between
2 and 21 GHz for VSWR<2. The process of improving the impedance bandwidth and measured results has been presented and discussed.
