Depth of the seating recess 30 is preferably formed to be slightly shallower than the thickness of the antenna (40). That is, the seating recess 30 is formed to be shallower than the thickness of the antenna 40 by about 0.5 mm. An inclined surface 32 is provided at one end of the seating recess 30. The inclined surface 32 is formed on the inner surface of one side wall of the rear case 22.

The rear plate 34 is installed on the inner surface of the rear case 22. The rear plate 34 reinforces the strength of the rear case 22 and performs a grounding role in the display unit 20. The rear plate 34 is preferably formed of a conductive metal material.

The rear plate 34 is formed with a reinforcement step 36 along its edge. The reinforcement step 36 is bent the edge of the rear plate 34 several times, and serves to reinforce the strength of the rear plate 34. The shape of the reinforcement step 36 is shown well in FIG. 5. Insertion cutouts 38 are formed at positions corresponding to the mounting recesses 30 among the ends of the rear plate 34 having the reinforcement step 36 formed therein. The insertion cutout 38 is formed by cutting a part of the reinforcement step 36, and its shape is illustrated in FIGS. 4 and 5.

The insertion cutout portion 38 has a predetermined gap between the bottom surface of the rear case 22. This is because the tip of the insertion cutout portion 38 is relatively higher than the bottom surface of the rear case 22. Of course, the seating recess 30 is formed at a position corresponding to the insertion cutout 38 so that the antenna 40 to be described below can be easily inserted.

Thus, the value of about 0.5mm may be larger enough that the rear plate 34 does not protrude too much, or may be smaller enough that it can be pressed by the rear plate 34. It is preferable that the thickness of the antenna 40 is thicker than the depth of the mounting recess 30 to have a value between 0.2 and 0.7 mm.

Meanwhile, FIG. 6 shows a configuration of another embodiment of the present invention. Herein, reference numerals of 100 units are given to components corresponding to the above embodiments, and only the main parts will be described for convenience of description.

In the present embodiment, a hooking protrusion 130 ′ is formed in the seating recess 130, and the hooking hole 142 is drilled at a corresponding position of the antenna 140 so that the hooking protrusion 130 ′ penetrates. The hook protrusion 130 ′ and the hook hole 142 serve to prevent the antenna 140 from being moved by an external force. At least two or more hook protrusions 130 'and hook holes 142 may be formed.

Hereinafter, the operation of the antenna mounting structure of the portable computer according to the present invention having the configuration as described above in detail.

In order to install the antenna 40, the rear plate 34 is first mounted on the rear case 22. When the rear plate 34 is mounted on the rear case 22, the insertion cutout 38 is positioned on the seating recess 30. That is, the insertion cutout portion 38 is positioned across the middle portion of the seating recess portion 30.

In particular, since the insertion cutout portion 38 is formed by partially cutting the reinforcement step 36, the tip thereof is relatively higher than the surface of the rear case 22, and the seating portion is inserted in the insertion cutout portion 38. The distance to the inner surface of the recess 30 is greater than the thickness of the antenna 40. Therefore, the antenna 40 may be more easily inserted into the seating recess 30, that is, between the seating recess 30 and the rear plate 34.

When the antenna 40 is completely seated inside the seating recess 30, a portion of the antenna 40 is pressed by the rear plate 34. This is because the thickness of the antenna 40 is thicker than the depth of the seating recess 30, the portion of the seating recess 30 is covered by the rear plate 34 (except for the reinforcement step 36). ), The antenna 40 is pressed by the rear plate 34 and fixed.

The other side of the antenna 40 pressed by the rear plate 34 is seated on the inclined surface 32. That is, as shown in FIG. 5, the portion of the antenna 40 seated on the inclined surface 32 is inclined and closely adhered to the inclined surface 32 by the elasticity of the antenna 40 itself. As the one end of the antenna 40 is in close contact with the inclined surface 32, the antenna 40 is forced in the direction inserted between the rear plate 34 and the rear case 22.

Thus, as indicated by arrows in FIG. 5, the antenna 40 has one end pressed by the rear plate 34 and the other end pushed by the inclined surface 32 such that the rear plate 34 and the rear case. It is firmly installed between the 22.

Meanwhile, in the embodiment illustrated in FIG. 6, when the antenna 140 is seated on the seating recess 130, the hook protrusion 130 ′ formed in the seating recess 130 is hooked by the antenna 140. 142 is inserted. As the hook protrusion 130 ′ is inserted into the hook hole 142 as described above, the antenna 140 does not randomly flow in the mounting recess 130.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self-evident.
