FEEDING STRUCTURE OF HOUSING WITH ANTENNA

摘要

A feeding structure of a housing with an antenna is provided. In the feeding structure, a flat antenna can be fixed inconspicuously to the outer surface of the housing which is hard to be affected by a metal component and power can be supplied to the flat antenna without providing a through hole causing poor appearance. The feeding structure comprises a housing (2); a decoration film (3) covering at least a part of the outer wall face of the housing (2); a flat antenna (6) held between the outer wall face of the housing (2) and the decoration film (3); and an electrode (7) provided on the inner wall face of the housing (2). A capacitor is formed by arranging the feeding section (6a) of the flat antenna (6) and the electrode (7) on the opposite sides of the housing (2) and noncontact power transmission and communication are performed for the flat antenna (6) on the outside of the housing (2) from the inside of the housing (2) by connecting an inductor (8) with the electrode (7).
