Abstract
This paper presents a wideband technique for a mobile handset antenna. The proposed method inserts a distributed LC resonator into a loop antenna in order to provide non-uniform resonance shifts; without the use of a multi-radiator the bandwidth can be increased from 320MHz (1900-2220MHz) to 880MHz (1750-2630MHz). As a result of the wide bandwidth and good radiation efficiency, the proposed antenna can be employed in DCS/PCS/WDCMA/Bluetooth mobile handsets.
