Small UWB Antenna using Triangular Elements

The small UWB antenna using the triangular elements, which is made of the printed circuit board without the wide ground plane, has been successfully developed. This antenna covers the wide band width from 3.1 GHz to 4.9 GHz and is small in order to be installed in the compact wireless USB-unit using UWB technique. This paper introduces its novel construction and the performance of the trial model antenna
