Abstract:
A multi-band antenna for use in a portable telecommunication apparatus has a continuous trace (11) of conductive material. The continuous trace has a first conductive portion (13) arranged in a first plane and a second conductive portion (15-16) arranged in a second plane. The second plane is different from the first plane. The first conductive portion has a feeding end (12) to be connected to radio circuitry in the portable telecommunication apparatus. The second conductive portion (15-16) has a distinctly smaller width than the first conductive portion (13).
