 The present invention relates to an antenna assembly and particularly to an antenna assembly mounted in an electronic device for wireless telecommunication.
 Following the development of communication technology, especially the development of Wireless Local Area Network (WLAN), Bluetooth and HomeRF, etc., many electronic devices have the function of wireless telecommunication in close range. To achieve the function, an antenna is used in an electronic device for receiving and transmitting signals. As disclosed in prior arts, an antenna is directly mounted in an electronic device by soldering or screwing. Thus, the antenna is exposed to outside and is easy to be damaged. Another disadvantage of this prior art is that the structure of mounting is immobile, which makes the assembly and the disassembly process inconvenient. This is time-consuming and requires special equipment.
 The present invention is directed to solving the above problems and satisfying the need for an antenna assembly to simplify the assembly and protect the antenna effectively.
 A primary object, therefore, of the present invention is to provide an antenna assembly which has a simplified structure for simplifying the assembly process of the antenna.
 Another object is to provide an antenna assembly to protect the antenna effectively from outer physical damage.
 In order to achieve the objects set forth, an antenna assembly in accordance with the present invention comprises a bracket, an antenna unit, an insulative housing and a connector unit. The bracket is mounted to an enclosure of a desktop computer. The antenna unit includes a substrate and an antenna body attached on the substrate. The insulative housing is attached to the bracket and receives the antenna unit. The connector unit includes a cable and a connector connected to an end of the cable, the cable having an opposite end passing through the bracket to connect with the antenna unit.
 Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
FIG. 1 shows a perspective view of an antenna assembly in accordance with an exemplar embodiment of the present invention;
FIG. 2 shows an exploded view of the antenna assembly of FIG. 1;
FIG. 3 shows the antenna assembly of FIG. 2 in another exploded view;
FIG. 4 shows a top view of the antenna assembly of FIG. 1; and
FIG. 5 shows an antenna assembly of the present invention assembled in a desktop computer.
 Reference will now be made to the drawing figures to describe the present invention in detail.
 Referring to FIGS. 1 to 3, an antenna assembly 1 in accordance with the present invention comprises a bracket 15, an antenna unit 10, an housing 14 and a connector unit 100.
 Particularly referring to FIGS. 2 and 3, the antenna unit 10 includes a substrate 19 and an antenna body 16. The substrate 19 is a rectangular insulative board. The antenna body 16 is mounted on a front surface of the substrate 19.
 The connector unit 100 comprises a cable 12 and a connector 13. The cable 12 connects the antenna body 16 with the connector 13 through the bracket 15. The cable 12 is a coaxial cable and serves as RF feeder of the antenna body 16. The connector 13 provides an electrical interface to an RF circuitry (not shown).
 The housing 14 is a hollow insulative cuboid, with a cuboid cavity 143 opened to backward and two locating wings 141 respectively protruding horizontally from opposite sides thereof. A first hole 142 is defined through each locating wing 141. A plurality of wedge shaped hooks 144 are formed on an inner sidewall of the cavity 143, with bevel surface of the hooks 144 facing rearward. Four posts 145 are formed respectively at four inner corners of the cavity 143.
 The bracket 15 is made of a sheet metal and provides a bracket body 151, a locating tab 152, a rectangular tab 155, two second mounting holes 153 and two holding tabs 154. The locating tab 152 bends forwardly from one end of the bracket body 151 and perpendicular to the bracket body 151. The rectangular tab 155 extends from an opposite end of the bracket body 151 and slightly bends forwardly. The two holding tabs 154 bend rearwardly from a lower edge of the bracket body 151 and perpendicular to the bracket body 151, and near two ends of the bracket body 151 respectively. A U-shaped notch 1521 is formed in the locating tab 152 for matching with an inserted screw nut (not shown). The two second mounting holes 153 are defined in the bracket body 151, respectively aligned with the first holes 142 in the locating wings 141 of the housing 14. A screw hole 1541 is defined in each holding tab 154 for holding other elements, such as a printed circuit board (PCB) (not shown).
 Particularly referring to FIG. 1 and 4, the substrate 19 is assembled in the cavity 143 of the housing 14 by engaging the substrate 19 between the posts 145 and the hooks 144. The substrate 19 is received in the housing 14 and positioned parallel to the bracket 15. The housing 14 is attached to the front surface of the bracket 15, with the first holes 142 aligned with the second holes 153 respectively. A screw 18 and a nut 17 engage each other through each first hole 142 of the housing 14 and each second hole 153 of the bracket 15, in order to attach the housing 14 to the bracket 15.
 In assembly, referring to FIG. 5, the antenna assembly 1 is mounted in an expansion slot (not labeled) in an enclosure 21 of the desktop computer 2 by fixing the bracket 15 to the enclosure 21. The housing 14 and the front surface of the bracket 15 expose to outside of the enclosure 21, so the communication of the antenna body 16 is not affected by the enclosure 21.
 In this embodiment, the antenna body 16 is protected by the insulative housing 14 out of the enclosure 21 of the desktop computer 2, thereby assuring normal performance of the antenna body 16 and preventing the antenna body 16 from outer physical damage. And with the structure of this present invention, the antenna assembly 1 can be assembled in or disassembled from the desktop computer 2 easily.
 It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
