Abstract :
UWB is a useful system for mobile communications. In this paper, a new antenna is proposed for UWB systems, it is analyzed by using the FDTD method and the antenna characteristics are obtained. It was achieved that the radiation characteristic of the antenna is approximately omnidirectional over all frequencies of the UWB by modifying an antenna element and a ground conductor. Those method and characteristics are obtained and the results are shown in figures. The results are useful for mobile communications.
