Abstract
In this paper, small UWB antenna with band-stop function for mobile handsets is proposed. A gap between radiator and under and side ground is adjusted for small size and broadband. A radiator is folded to the back side of PCB for miniaturization and tapered feeding structure is used to enhance matching characteristic. A antenna clearance has a size of $14{\times}14\;mm^2$ and a size of radiator is $10{\times}7\;mm^2$. It covers all UWB band from 3.15 GHz to 4.75 GHz and from 7.2 GHz to 10.2 GHz for VSWR<2 and has band stop characteristic at 5.8 GHz. A maximum gain is measured as 5.85 GHz. In case conventional handset case is considered, it also covers all UWB and a maximum gain is measured from -2 dBi to -2 dBi.
