Synthesis of Fractal Antenna Arrays

This work involves the overlaps of antenna theory, fractal geometry, and numerical calculations. Its goal is to investigate how random or periodic antenna array geometry can be improved through the use of fractals. Using Mat lab software we are going to develop the programs, we will plot the radiation of linear/planar antenna arrays. We were able to correctly analyse radiation of three two-dimensional arrays. Here we are going to develop another program whose purpose was to generate fractals was used to allow us to characterize the radiation properties of periodic and random arrays. A fractal is a recursively generated object having a fractional dimension. Many objects, including antennas, can be designed using the recursive nature of a fractal. Iterated Function System (IFS) is used to generate the fractal array (Sierpinski gasket). Once these antenna arrays are generated, the resulting radiated field is calculated using scripts which are going to write in MATLAB. Fractal antenna theory uses a modern (fractal) geometry that is a natural extension of Euclidian geometry. In this report, attention is called to this developing, but already quite large, field of study. After that we are further going to extend it for Sierpinski gasket using fractal array.
