Claim Text:
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 and included in a portable communication device; 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 at least one structure 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 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, wherein the multi-band antenna provides a substantially similar combined amount of resistance and reactance measured at an input/output connector and radiation pattern in the multiple ranges of frequencies, 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.
