| Abstract(in English) | An improvement method of radiation efficiency for mobile handsets by using distributed feed has been proposed in this paper. Higher effirciency has been realized because the local electric field in the vicinity of feed point decreases by array feed. The technique of distributed feed and the simulation model are described before the effects of this method are obtained calculating current distribution and near electric field. The valid range of this method has been clarified evaluating the relation between efficiency and antenna arrangement. |
