The document discusses the design and analysis of three fractal antennas. The first is a hybrid fractal antenna combining elements of the Sierpinski carpet and Giuseppe Peanu fractals, allowing for narrow-band operation in the S-band. The second is a multi-band fractal antenna created through an iterative process of cutting circles out of squares, enabling it to resonate at five frequencies from 3-12 GHz. The third is an ultra-wide band fractal antenna made by cutting hexagonal holes in a circular patch through five iterations, optimized using parametric analysis. Dimensions, resonant frequencies, radiation patterns, and gains are analyzed for each antenna. Fractal geometry is shown to increase electrical length while
