Patent ID: 6963309

Claim:
A multi-band antenna for use in a portable telecommunication apparatus, the antenna comprising a continuous trace of conductive material, the continuous trace having a first conductive portion arranged in a first plane and a second conductive portion arranged in a second plane, the second plane being different from the first plane, the first conductive portion having a feeding end to be connected to radio circuitry in the portable telecommunication apparatus, characterized in that the second conductive portion has a distinctly smaller width than the first conductive portion; wherein the first conductive portion has a rectilinear extension, whereas the second conductive portion is meander-shaped; wherein the first plane is parallel to the second plane and wherein the continuous trace has a third conductive portion, which interconnects the first conductive portion with the second conductive portion and which is nonparallel to the first and second planes; wherein the third conductive portion has a width which is essentially equal to the width of the second conductive portion; and wherein the third conductive portion is connected between a second end of the first conductive portion, opposite its feeding end, and a first end of the second conductive portion, and wherein the third conductive portion extends orthogonally between the first and second planes.
