  • Mobile device
    Patent number: 9609094
    Abstract: A mobile phone includes an antenna housing made of a resin, an insert metal plate made of a metal, which is buried in the antenna housing and has a connecting portion exposed from an outer surface of the antenna housing, and an antenna element provided on the outer surface of the antenna housing and brought into contact with the connecting portion. A boundary between a region where the antenna element is in contact with the connecting portion and a region where the antenna element is in contact with the antenna housing is nonlinear. With this structure, a mobile device is provided in which deterioration of the antenna performance is reduced even in the event of being subjected to an excessive external shock.
