Multilevel antennae

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 and second non-overlapping frequency bands, the internal antenna element comprising a plurality of geometric elements, wherein:
• not all of the plurality of geometric elements have the same size;
• each of the plurality of geometric elements is electromagnetically coupled to at least one other of the plurality of geometric elements either directly through at least one point of contact or through a small separation providing coupling;
• each of the plurality of geometric elements has the same number of sides, the perimeter of the antenna element having a different number of sides than each of the plurality of geometric elements;
• a first set of the plurality of geometric elements has an area of a first size configured to operate at the first frequency band, a second set of the plurality of geometric elements has an area of a second size configured to operate at the second frequency band, the second set of geometric elements residing substantially within the first set of geometric elements;
• the first and second sets of geometric elements define empty spaces in the antenna element 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;
• the antenna element provides a substantially similar impedance level and radiation pattern in the at least the first and second frequency bands;
• the plurality of geometric elements is arranged such that the antenna element does not comprise a group of single band antennas that respectively operate in the at least first and second frequency bands;
• and
• a geometry of the antenna element is not substantially self-repeating.
