Abstract

A laptop computer (1) removably receives a plug-in combination unit (2). The plug-in combination unit includes a drawer (20), an extension device (4) such as a CD-ROM or disk drive, and an antenna assembly (3). The drawer includes a receiving space (21) for accommodating the extension device. A remainder space (22) is left in the drawer after the drawer accommodates the extension device. The antenna assembly includes an antenna element (31) received in the remainder space of the drawer.

Claims

1. An electrical device comprising:

a host defining a receiving cavity; and

a plug-in electrical unit being removably received in the receiving cavity of the host, and comprising a drawer and an antenna assembly, the drawer defining a remainder space, the antenna assembly comprising an antenna element being received in the remainder space.

2. The electrical device as claimed in claim 1, wherein the plug-in electrical unit further comprises an extension device accommodated by the drawer, the remainder space being left in the drawer after the drawer accommodates the extension device.

3. The electrical device as claimed in claim 2, wherein the extension device is a CD-ROM, a floppy disk drive or a hard disk drive.

4. The electrical device as claimed in claim 1, wherein the host is a body portion of a laptop computer.

5. The electrical device as claimed in claim 1, wherein the antenna assembly further comprises an electrical connector, and a feeder cable electrically interconnecting the antenna element and the electrical connector.

6. The electrical device as claimed in claim 5, wherein the electrical connector is a coaxial connector and is securely mounted on the drawer.

7. A method of assembling an antenna in an electrical device, comprising:

providing an antenna assembly comprising an antenna element;

providing an extension device and a drawer, the drawer comprising a receiving space for accommodating the extension device, a remainder space being left in the drawer after the drawer accommodates the extension device;

mounting the antenna element in the remainder space; and

inserting the drawer into the electrical device.

8. The method as claimed in claim 7, wherein the electrical device defines a receiving cavity for removably receiving the drawer.

9. The method as claimed in claim 8, wherein the electrical device is a laptop computer.

10. The method as claimed in claim 9, wherein the extension device is a CD-ROM, a floppy disk drive or a hard disk drive.

11. The method as claimed in claim 7, wherein the antenna assembly further comprises an electrical connector, and a feeder cable interconnecting the antenna element and the electrical connector.

12. The method as claimed in claim 11, wherein the electrical connector is a coaxial connector and is securely mounted on a rear portion of the drawer.

13. An electronic assembly comprising:

a host defining a receiving cavity defining an opening in communication with an exterior;

a metallic drawer compliantly and removably received in said cavity, said drawer defining a primary space receiving a drive therein, and a secondary space, beside said primary space, receiving an antenna assembly therein.

14. The assembly as claimed in claim 13, wherein said primary space and said secondary space are juxtaposed with each other along a lengthwise direction of said host 15. The assembly as claimed in claim 13, wherein said antenna assembly includes an antenna element located adjacent to the opening, and a connector located away from said opening and connected to said antenna element via a wire.
