Summary:
Recently, there has been enormous interest in ultra-wideband (UWB) wireless systems for shortrange and high-speed wireless communications. The Federal Communication Commission (FCC) has released three basic areas of applications, in the areas of communication, positioning and imaging. Currently, a resistively loaded dipole antenna has been proposed as one of the antennas with a broadband characteristic. By using a dipole antenna with continuous resistive loading, it is possible to create a small traveling wave antenna with a broadband characteristic [1]? [3]. However, it is not easy to produce the necessary continuous resistance distribution. In this paper, a printed monopole antenna with resistive loading is developed for UWB applications. First, a loading technique of lumped resistor on the antenna element based on the well-known Wu-King profile is proposed. This technique enables the fabrication of the resistively loaded printed monopole antenna using surface mount chip resistors. Next, after evaluating the simulated and the measured results of the return loss characteristics, the gain and the measured results of the radiation patterns are presented and discussed.
