Patent ID: 8330659

Claim:
A wireless communications device having a multi-band antenna system located entirely within the wireless communications device; the multi-band antenna system having an antenna element that functions across an entirety of each of at least first and second cellular frequency bands and not comprising a set of antenna elements that respectively operate independently in the at least first and second cellular frequency bands, the antenna element comprising an overall structure that is formed by four or more generally identifiable electromagnetically coupled geometric elements of different sizes; each of the geometric elements having the same number of sides with the contact regions between adjacent geometric elements being different among at least some of the four or more geometric elements, the overall structure having a different number of sides than each of the four or more geometric elements; at least one of either a perimeter of contact or an area of overlap between said four or more geometric elements is only a fraction of a total perimeter or a total area of the four or more geometric elements, respectively, for a majority of said four or more geometric elements such that it is possible to generally identify the majority of said four or more geometric elements within said overall structure; a first set of the four or more geometric elements has an area of a first size and transmits and receives wireless signals in the first cellular frequency band, a second set of the four or more geometric elements has an area of a second size and transmits and receives wireless signals in the second cellular frequency band, each of the first and second sets of geometric elements comprising two or more geometric elements, the first and second sets of geometric elements together occupying an area of a size in the structure that is substantially smaller than the sum of the first size and the second size; said first and second sets of geometric elements defining empty spaces in the overall structure to provide a first winding current path within the first set of geometric elements and a second winding current path within the second set of geometric elements; and the antenna element simultaneously receives electromagnetic waves corresponding to each of at least the first and second cellular frequency bands.
