3Gスマートフォンに組み込んだUWB対応アンテナの検討

抄録

In recent years, Ultra wideband (UWB) technology has been drawing attention as a promising technology in order to materialize ubiquitous network. Third-Generation (3G) smart phones which employ the UWB technology have been hot. In this paper, a UWB antenna built into the smart phone was investigated. As a result, the antenna with the VSWR less than 2.1 at both 3G and UWB frequency bands, which was enough in practical use, was designed and developed.
