In the recent years antenna design appears as a mature field of research. It really is not the fact because as the technology grows with new ideas, fitting expectations in the antenna design are always coming up. In the past, it followed a simple method based on some Euclidean geometry comparatively. However, the wide-spoken attractive fractal antennas do not follow this design. Their complex structure is built up through replication of a base shape. In this paper, the performances of a newly shaped fractal structures have been investigated using Ansoft HFSS 3D electromagnetic simulation tool. The design was carried out using FR4 as the substrate and copper as antenna material. The designed antennas resonate at multiple frequencies with very low return loss and VWSR values. The self-similarity and space filling properties of fractals have been exploited to achieve radiation in C, J and X band regions.
