Abstract
An antenna assembly (20) is mounted on a metal hinge base (16) of an electronic device, and includes a printed circuit board (PCB) (22), an antenna (24), a metal sheet (26) and a coaxial cable (28). The PCB has a first surface (221) and a second surface (223) parallel to and spaced a distance from the first surface. The antenna and the metal sheet are respectively disposed on the first surface and the second surface of the PCB. The metal hinge base has a metal block (162) connecting with the metal sheet. The cable has a conductive core wire (282) and a ground shield (284) around the core wire. The core wire and the ground shield respectively electrically connect with the antenna and the metal sheet.
Claims9
An antenna assembly used in a portable electronic device, comprising:
- a printed circuit board (PCB) having opposite first and second surfaces;
- a metal sheet attached to the second surface of the PCB, whereby said PCB is fixed to a metal hinge base of the portable electronic device at a position such that the metal sheet electrically connects with the metal hinge base;
- a flat antenna mounted on the first surface of the PCB;
- and
- a signal transmitting cable having a core wire electrically connecting with the antenna, and a ground shield surrounding the core wire electrically connecting with the metal sheet.
An antenna assembly adapted to mount on a metal hinge base of an electronic device, comprising:
- an antenna provided on a first surface;
- a ground means mounted on a second surface;
- and
- a coaxial cable including a core wire and a ground shield around the core wire, the core wire electrically connecting with the antenna, and the ground shield connecting with the ground means;
- wherein the ground means electrically connects with the metal hinge base.
An antenna assembly used in a portable electronic device comprising:
- a printed circuit board (PCB) having opposite first and second surfaces;
- a flat antenna mounted on the first surface;
- a grounding pad mounted on the second surface and adapted to be connected to a metal base of the device;
- and
- a signal transmission cable including a core wire extending from the second surface through an aperture of the printed circuit board to the first surface and connected to the flat antenna, and a ground shield surrounding the core wire terminating at the second surface without extending through the aperture but being connected to the grounding pad;
- wherein
- said metal base is used as a hinge base of said device.
