Multilevel antennae
First Claim
1. An apparatus comprising:
- an internal antenna element having a multi-band behavior, the antenna element being concealed within the apparatus and configured to operate in at least first, second and third frequency bands, each of the at least first, second and third frequency bands extending between two limiting frequencies;
the antenna element comprising a plurality of closed figures bounded by the same number of sides, wherein each of the closed figures is directly or proximately linked to at least one other of the closed figures such that electromagnetic power is exchanged between the closed figures either directly through at least one point of contact or through a small separation providing coupling;
wherein, for at least most of the closed figures, a region or area of contact, intersection, or interconnection between the closed figures is less than 50% of their perimeter or area;
wherein not all of the closed figures have the same size, and the perimeter of the antenna element has a different number of sides than the closed figures that compose the antenna element;
the antenna element including at least first, second, and third portions, the first portion having a first geometry configured to operate at the first frequency band, the second portion being located substantially within the first portion and having a second geometry configured to operate at the second frequency band, and the third portion being located substantially within the first portion and having a third geometry configured to operate at the third frequency band, the first portion comprising substantially all of the antenna element; and
wherein a geometry of the antenna element is not substantially self-repeating.

Abstract
A multi-band antenna includes at least one structure usable at multiple frequency ranges. The structure includes at least two levels of detail, with one level of detail making up another level of detail. The levels of detail are composed of closed plane figures bounded by the same number of sides. An interconnection circuit links the multi-band antenna to an input/output connector and incorporates adaptation networks, filters or diplexers. Each of the closed plane figures is linked to at least one other closed plane figure to exchange electromagnetic power. For at least 75% of the closed plane figures, the region or area of contact, intersection, or interconnection between the closed plane figures is less than 50% of their perimeter or area. Not all of the closed plane figures have the same size, and the perimeter of the structure has a different number of sides than its constituent closed plane figures.
