Optimization of the Sierpinski Carpet Fractal Antenna

The Sierpinski Carpet fractal antenna is studied in terms of optimality. A 3D full-wave FDTD model of the structure is developed and used in conjunction with a neural network optimization procedure. An original engineering design based on the idea of a broken fractal geometry is suggested. The modified fractal antennas are shown to have the capability of being optimized, in terms of its input impedance, in a narrow frequency band.
