摘要

介绍了覆盖手机GSM850/GSM900/DCS1800/PCS1900/UMTS2100的多波段天线。该天线是一种改进的PIFA天线，由PIFA和t支路组成。低频段和高频段的带宽是通过低频段和高频段臂之间的间隙耦合来实现的。通过t型支路与外壳边缘金属环的耦合，提高了低频段的带宽。给出了利用SEMCAD进行实验和仿真的结果。

Design and analysis of multi-band antenna for mobile handset applications

Multi-band antenna covering GSM850/GSM900/DCS1800/PCS1900/UMTS2100 in mobile phones is presented. The proposed antenna is kind of a modified PIFA which consists of PIFA and T-branch. The bandwidth in low and high band is achieved using gap coupling between low and high band arm. And also bandwidth in low-band is improved by the coupling between T-branch and metal ring along the edge of the housing. Experimental and simulation results using SEMCAD are presented.
