This paper proposes a planar printed ultra-wideband antenna for eight-band LTEIGSMIUMTS WWAN wireless USB dongle applications. An inductive shorted strip with a chip capacitor loaded is employed in order to improve the characteristics if small-size terminal antennas which usually have a narrow band over the lTE700lGSM850 190 0 (698-960 MHz) and DCSI800lPCSI90 0 IUMTS2100ll TE230012500 (1710-2690 MHz) operation. Easily printed on a 08-mm thick FR4 dielectric substrate o/size 20 x 70 mm� the proposed antenna structure occupies a compact size if 20xJ9 mm2 Then the proposed design can be attached to laptop computer by the USB inteljace. The proposed antenna isfobricated and tested, and good radiation peljarmances if the .fobricated antenna are obtained Keywortk-surfaee-lIIO unted printed IIIIten na; wireless lISB dongle antenna,· eltip eopoeitllll ee em!Jedded 1.
