An Internal Triple-Band Antenna for PCS/IMT-2000/Bluetooth Applications
Dong-Uk Sim, Jung-Ick Moon, and Seong-Ook Park, Member, IEEE
Abstract―An internal triple-band antenna fed by a microstrip line is proposed for operating PCS, IMT-2000, and Bluetooth bands. By using the two branches of meander line, the desired resonant frequencies can be achieved. A broadband characteristic for each band is optimized by tuning the parts of radiating patch and size of each strip line segment. The proposed antenna and substrate are small enough to be built in a practical mobile handset. Details of the proposed technique and experimental results are presented and discussed.
