Abstract: A related analysis of fractal antennas with distinct geometry is done in this paper. Patch shapes (square, hexagon, and circle), which are suitable for ultra-wideband applications have been considered. The fractal monopole square fractal is designed by novel Giuseppe Peano geometry, hexagon fractal patch antenna is formed by Koch structure and circle by Minkowski fractal elements. Matching for microstrip feed input is provided by rectangular ground plane. FR4 substrate has been used for fabrication purpose. The analogy is established on the output values of return loss, bandwidth, VSWR, group delay, gain, directivity and axial ratio. This investigation will help the design engineers to select the preferred aerial according to fractal geometry. The proposed antennas find its application in X-ray, W-LAN, WI-max, biomedical applications and so on.
