Multilevel antennae
First Claim
1. Multilevel antenna characterised in that it includes at least one multilevel structure which is a set of polygonal or polyhedral elements of the same type (same number of sides or faces) although not necessarily of the same size, the multilevel structure and the polygons or polyhedrons which form it having different geometry, said polygons or polyhedrons being electromagnetically coupled to each other so that the area of contact between elements does not cover a major part of the perimeter or area at least in most of the polygons or polyhedrons, so that the area of contact between elements is under 50% of the perimeter or area in at least 75% of the polygons or polyhedrons, thereby allowing to geometrically distinguish in the multilevel structure the majority of the polygons or polyhedrons which form it.

Abstract
Antennae in which the corresponding radiative element contains at least one multilevel structure formed by a set of similar geometric elements (polygons or polyhedrons) electromagnetically coupled and grouped such that in the structure of the antenna can be identified each of the basic component elements. The design is such that it provides two important advantages: the antenna may operate simultaneously in several frequencies, and/or its size can be substantially reduced. Thus, a mult-band radioelectric behavior is achieved, that is, a similar behavior for different frequency bands.
