  • Patent number: 9544405
    Abstract: Aspects of the disclosure provide a terminal device that includes an antenna element and an interface component. The antenna element is mounted on a casing of the terminal device to transmit/receive electromagnetic waves. The interface component is configured to couple an external device with the terminal device for a wired transmission. The interface component includes a metal shell configured to have a fixed potential state to shield the wired transmission from noise when the interface component is active for the wired transmission, and to have a floating state to avoid affecting the antenna element for transmitting/receiving electromagnetic waves when the interface component is idle.
