| Research Abstract |
Ultra-wideband (UWB) radio systems have recently attracted considerable attention for wireless high-speed communication. The purpose of this study is to present fundamental techniques for the realization of basic components (antenna, filter and microwave amplifier) that are useful for UWB radio systems. The achievements obtained in this study are the development of effective way for constructing ultra-wideband planar-type antennas, the proposal of techniques for obtaining ultra-high efficiency in microwave amplifiers and the realization of microwave filter having ultra-high performance with small shape. These achievements may contribute to the realization of UWB radio systems.
