A MULTI-BAND ANTENNA FOR USE IN A PORTABLE TELECOMMUNICATION APPARATUS

摘要

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 ).
