| Abstract: | A simple and compact microstrip-fed ultra wideband (UWB) printed monopole antenna is presented.The antenna is composed of a circular radiator and a finitely grounded plane.The antenna occupies about 16.62 GHz absolute bandwidth and 142.7%relative bandwidth covering from 3.38 GHz to 20 GHe with voltage standing wave ratio (VSWR) below two.A quasi-omnidirectional and quasi-symmetrical radiation pattern in H plane is obtained in the whole bandwidth.The high performance of the antenna is validated with measured and simulated results given.The antenna can be applied for the system design of UWB wireless communication. |
