Patent ID: 8154463

Claim:
A multi-band antenna including: at least one multilevel structure; wherein the multilevel structure comprises a set of polygonal or polyhedral elements having the same number of sides or faces; wherein each of said elements is electromagnetically coupled to at least one other of said elements either directly through at least one point of contact or through a small separation providing coupling; wherein for at least 75% of said polygonal or polyhedral elements, the region or area of contact between said polygonal or polyhedral elements is less than 50% of the perimeter or area of said elements; wherein not all the polygonal or polyhedral elements have the same size and the perimeter of the multilevel structure has a different number of sides than the polygonal or polyhedral elements that compose the multilevel structure; wherein said multi-band antenna is entirely inside of a portable communications device; wherein said portable communications device is a handset; wherein the multi-band antenna system further includes a matching network connected to an input/output port; wherein a level of impedance and radiation pattern of said multi-band antenna are similar in several frequency bands so that the multi-band antenna maintains basically a same radio-electric characteristics and functionality in said bands to allow the multi-band antenna to operate simultaneously in several frequencies and thereby be able to be shared by several communication services; wherein said multi-band antenna operates at multiple frequency bands, and wherein at least one of said multiple frequency bands is operating within the 800 MHz-3600 MHz frequency range; and wherein said portable communications device provides at least one cellular service across the entire 1850-1990 MHz frequency range.
