In this letter, a small and an internal ultra-wideband (UWB) antenna for wireless USB of mobile handsets is proposed for UWB service in which bandstop function of 5.8-GHz wireless local area network band is required.The ground is partially removed and the microstrip feed line is gradually tapered to obtain enhanced impedance bandwidth. λ/4 short slots for bandstop function are modified into L-type to be accommodated in a small-sized antenna. From the measured results, wide bandwidth of 3.15-4.75 and 7.2-10.2 GHz is achieved while 5.8 GHz is notched. Three different shapes of conventional mobile terminals are also considered for measurement. © 2011 Wiley Periodicals, Inc.
