A multi-band antenna includes at least one structure useable 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. |

1. A multi-band antenna including:
at least one structure for the multi-band antenna useable at three ranges of frequencies, each of the three ranges of frequencies extending between two limiting frequencies, the at least one structure including at least two levels of detail, wherein one level of detail makes up another level of detail, the at least two levels of detail being composed of closed figures bounded by the same number of sides, the sides comprising one or more of straight lines, portions of circles and portions of ellipses; and the at least one structure including at least three portions, a first portion having a first geometry configured to operate at a range of frequencies of the three ranges of frequencies, a second portion located substantially within the first portion and having a second geometry configured to operate at a range of frequencies of the three ranges of frequencies and a third portion located substantially within the first portion and having a third geometry configured to operate at a range of frequencies of the three ranges of frequencies, the first portion comprises substantially all of the at least one structure, 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 75% of the closed figures, the region or area of contact, intersection, or interconnection between the closed figures is less than 50% of their perimeter or area, and wherein not all of the closed figures have the same size and the perimeter of the at least one structure has a different number of sides than the closed figures that compose the at least one structure. |
