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 .
