Multilevel and space-filling ground-planes for miniature and multiband antennas. In addition the fractal nature of the antenna shrinks its size, antejnes the use of any components, such as inductors or capacitors.

In other words, the self-similar aspect was the underlying requirement, along with origin symmetry, for frequency ‘independence’. Lignes de transmission, resonateurs, filtres et elements reseau passifs fractals et de remplissage de l’espace. Fractal antennas are now ubiquitously applied in commercial and government applications around the globe.

Fractal antenna ground counterpoise, ground planes, and loading elements and microstrip patch antennas with fractal structure.

The first fractal “antennas” were, in fact, fractal “arrays”, with fractal arrangements of antenna elements, and not recognized initially as having self-similarity as their attribute.

From Wikipedia, the frachales encyclopedia. Such fracta,es antennas are also referred to as multilevel and space filling curvesbut the key aspect lies in their repetition of a motif over two or more scale sizes, [1] or “iterations”.

A fractal antenna’s response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously.

Computer search methods and antenna simulations are commonly used to identify which fractal antenna designs best rfactales the need of the application.

This makes the antenna so that it has many different resonances which can be chosen and adjusted by choosing the proper fractal design.

Owing to the fact that DNA is a self-similar, electrically conducting molecule, it is hypothesized that DNA acts as a fractal antenna in the presence an external electromagnetic field. Dr Cohen possesses a broad scope of knowledge across many fields, which has led him down many roads throughout his career. By using this site, you agree to the Terms of Use and Privacy Policy.
