　An ultra-wideband (UWB) technology draws attention as a promising technology in order to materialize ubiquitous network. Considering a UWB radio communications system installed on small devices, such as mobile and wearable devices, from a view point of a cost, production, and miniaturization of devices, ultra-wideband antenna with a feeder line should be formed on a printed circuit board. In this study, a broadband dipole antenna with fan-shaped and trapezoidal elements with a microstrip feeder line, formed on a printed circuit board, was investigated. As a result, it was found that the antenna with the VSWR characteristics less than 2.0 and relative bandwidth of 110 % over the frequency band of 3.1 GHz to 10.8 GHz were obtained from the analyses and measurements.
