  • Publication number: 20090115669
    Abstract: A wireless communication device includes a housing and an antenna unit. The antenna unit is disposed on the outer or inner surface of the housing. A protective layer is optionally disposed to cover the outer surface of the antenna unit and, even more, at least a portion of the housing. Thus, the antenna unit separated from the circuit board does not occupy the layout region of the circuit board, so that the layout region of the circuit board can be used for other purposes. Moreover, the antenna unit formed on the housing can enhance the performance of the wireless communication device for transceiving signals.
