Abstract
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.
