Patent ID: 7342539

Claim:
Wireless communication device comprising: a loop antenna element including, a first section provided in and extending a length in a first plane, a second section spaced from the first section and provided in and extending a length in the first plane, where the second section extends along the same line as the first section or has a curvature which is a continuation of the curvature of the first section, a third continuous section provided in a second plane essentially parallel to the first plane and essentially aligned with the first and second sections wherein a length of the third continuous section is at least as great as combined lengths of the first and second sections, a fourth and a fifth section interconnecting antenna sections provided in the first and second planes, wherein the antenna sections form a three-dimensional structure having a substantial two-dimensional extension in at least one of the first and second planes, and a printed circuit board including a ground plane and radio circuits for the loop antenna element, wherein the antenna element sections are provided along the sides of and bound by the printed circuit board.
