1. A multi-band antenna including at least one multilevel structure wherein the multilevel structure includes at least one antenna region comprising a set of polygonal or polyhedral elements having the same number of sides or faces, wherein each of said elements in said antenna region is electromagnetically coupled to at least one other of said elements in said region either directly through at least one point of contact or through a small separation providing said coupling, wherein for at least 75% of said polygonal or polyhedral elements, the region or area of contact between said polygonal or polyhedral elements is less than 50% of the perimeter or area of said elements, wherein not all of the polygonal or polyhedral elements have the same size, and wherein the perimeter of the multilevel structure has a different number of sides than the polygons that compose said antenna region, and further wherein a plurality of polygons of said antenna region are generally identifiable as a geometrical element defined by the free perimeter thereof and the projection of ones of the longest exposed perimeters thereof to define the least number of polygons within said region necessary to form said generally distinguishable elements where said polygon perimeters are interconnected.
