Patent ID: 7911394

Claim:
A handheld wireless device comprising: an antenna element, the antenna element including a feeding point; a ground plane, the ground plane operating in cooperation with the antenna element; a printed circuit board, the printed circuit board including a conducting layer; a feeding means, the feeding means being arranged on the printed circuit board; and a dielectric support; wherein the antenna element is arranged on the dielectric support; wherein the feeding means are coupled to the feeding point of the antenna element; wherein the ground plane comprises: a first conducting surface and a second conducting surface, each of the first conducting surface and the second conducting surface having an elongated shape with two opposite ends; wherein the first conducting surface is arranged as the conducting layer of the printed circuit board; and a conducting strip, the conducting strip connecting an end of the first conducting surface with an end of the second conducting surface and allowing current to flow between the first conducting surface and the second conducting surface; wherein the conducting strip is narrower than a width of the first conducting surface and a width of the second conducting surface; wherein the antenna element is shaped as a structure comprising: a plurality of conducting polygon, the plurality of conducting polygons each having the same number of sides; wherein the plurality of conducting polygons of the structure are electromagnetically coupled via either capacitive coupling or ohmic contact; wherein a contact region between directly connected conducting polygons of the plurality of conducting polygons of the structure is smaller than half of a perimeter of the directly connected conducting polygons in at least seventy-five percent of the plurality conducting polygons of the structure; and wherein the antenna element is arranged adjacent to said end of the first conducting surface.
