Fractal Antennae - an ongoing research project by Afroditi Psarra

The miniaturization of electronic devices has led to the development of what is known as fractal antennas - miniaturized antennas that use an iterative function system to create a fractal element at a reduced size. The term "fractal" was first used by mathematician Benoit Mandelbrot in 1975. Mandelbrot based it on the Latin frāctus meaning "broken" or "fractured", and used it to extend the concept of theoretical fractional dimensions to geometric patterns in nature. One of the properties of fractals geometry is that it can have an infinite length while fitting in a finite volume. The radiation characteristic of any electromagnetic radiator depends on electrical length of the structure. By using the property of fractal geometry in antenna design one can increase the electrical length, keeping the volume of the antenna the same.
