Abstract :
In this communication, we propose a simple and compact printed ultrawideband (UWB) antenna. The antenna is mainly composed of a monopole section and a quasi-transmission line section. The input signal from the feed line first passes through the line section then enters the monopole. The quasi-transmission line section provides different functions as the operating frequency changes. It serves not only as an impedance matching circuit but also a main radiator, which leads to the UWB performance of the antenna. The resonance mechanisms across the full band are described, followed by a thorough study of the antenna´s geometrical parameters.
