Abstract

Fractal or multi-fractal aerials. Aerial consisting of a conductor or superconductor material body characterized by each of its parts having the same and/or similar form to the overall structure of the object, but at a different level of scale. In the physical version it consists of abstract mathematical objects known as fractals or truncated multi-fractals, which may display a multifrequency behaviour according to the number of operating bands or frequencies and the separation between them.
