Abstract :
A fan-shaped antenna has been proposed for UWB communications systems [T. Kondo et al., 2004][H. Nakano et al., 2006]. The fan-shaped antenna is a card-type antenna, where the radiation element and the ground plate lie in the same plane. The card-type structure facilitates the use of the fan-shaped antenna in PC card devices for personal computers or inside mobile phone handsets. Subsequently, an elliptical antenna, where the fan-shaped element in [T. Kondo et al., 2004][H. Nakano et al., 2006] is replaced with an elliptically shaped conducting ring, has been investigated and its radiation characteristics have been compared to those of the fan-shaped antenna [S. Hattori et al., 2005] [H. Nakano et al., 2005]. It is found that the elliptical and fan-shaped antennas have similar antenna characteristics.
