Abstract
In recent years, Ultra Wideband (UWB) radio technologies have been gaining a lot of attention for high-speed, large-capacity communication at close range. Small dimensions which allow these technologies to be built into electronic devices, broadband VSWR characteristics, and omni-directional radiation patterns in the horizontal plane are required for UWB antennas. In this paper, an UWB antenna with omni-directional radiation patterns in the horizontal plane, which can be built into a USB memory case, is proposed. The characteristics of the antenna formed on a printed circuit board are investigated. It was found that the proposed antenna performed with good VSWR characteristics and radiation patterns at the UWB frequencies.
