Abstract
The monopole dumbbell-shaped antenna fed by a 50 Ω microstrip line for ultrawideband (UWB) application is studied. By tuning the dumbbell-shaped radiator and height of the feed gap (D), the monopole antenna has a 2:1 VSWR (return loss < 10 dB) from 2.89 to more than 15 GHz. The bandwidth covered 3.1-10.6 GHz, which has approved by the Federal Communications Commission as a commercial UWB band. Moreover, the antenna features near omnidirectional characteristics in the operation range and good radiation efficiency. The UWB, monopole characteristics of the antenna are confirmed experimentally.
