Ultra-Wideband (UWB) Technology
Fujitsu Components has demonstrated the world’s first UWB external antenna samples, embodied with our core UWB antenna technology and a superior positioning mechanism, for optimum directional matching.
Introduction
Fujitsu Components has successfully developed the world’s first ultra-wideband (UWB) ring filter and UWB plane antenna with the world’s highest-class performance per unit area. The filter and the antenna, key components of UWB devices, are pattern-formed on a printed circuit board, which allowsthe implementation of small, low-profile packages.Fujitsu Components also provides a broad range of services from media storage engineering and manufacturing through System Device Products, including wireless technology products.
