Abstract

In this paper, an ultra-wideband (UWB) printed dipole antenna with semicircular dipoles is presented. A balanced microstrip line is used for feeding the dipole antenna. By introducing the loading disc, an ultra wide frequency band from 3.2 GHz to 15.6 GHz with VSWR < 2 is obtained. Through analyzing the surface current of the antenna, the equivalent array radiation models of standing wave current and traveling wave current are obtained. These models can well explain the antenna's radiation characteristic, which matches measured results well.
