## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This Application claims priority of Taiwan Patent Application No. 097107859, filed on Mar. 6, 2008, the entirety of which is incorporated by reference herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an antenna packaging method, and in particular relates to an antenna packaging method utilizing a package with decreased size.
2. Description of the Related Art
FIG. 1a shows a conventional antenna package disclosed in the People's Republic of China Patent NO. CN 2801697Y, wherein a plurality of packaging blocks 10 is provided, the packaging blocks 10 overlap with each other, and elements of the antenna are separately packaged by the packaging blocks 10. Conventionally, the packaging blocks 10 are thick, and the elements of the antenna are arranged disorderly. Therefore, the size of the antenna package is large.
With reference to FIG. 1b, conventionally, a down converter 20 and a dish (not shown) are packaged in a same antenna package. However, the shape of the down converter 20 cannot match the shape of the dish. Thus, packaging the down converter and the dish in different layers is required, and size of the antenna package is further increased.
BRIEF SUMMARY OF THE INVENTION
A detailed description is given in the following embodiments with reference to the accompanying drawings.
An antenna packaging method is provided. First, a first dish, a second dish, a third dish, a first bracket, a second bracket, a third bracket, a first arm, a second arm and a third arm are provided, wherein each of the first, second and third dishes has a central area. Then, a packaging unit is provided. Next, the first dish, the second dish and the third dish are overlapped with other. Then, the packaging unit is fixed to the first dish, the second dish and the third dish. Next, the first arm, the second arm and the third arm are fixed to the packaging unit. Finally, the first bracket, the second bracket and the third bracket are fixed to the packaging unit, wherein the first bracket, the second bracket and the third bracket correspond to the central area.
In the embodiment of the invention, the first bracket, the second bracket and the third bracket are disposed corresponding to the concave surface.

The first bracket 141, the second bracket 142 and the third bracket 143 are fixed to the first packaging bracket 131, and the second packaging blocks 132 are fixed to the convex surface 111. The first arm 151, the second arm 152 and the third arm 153 are fixed to the first packaging block 131 and the second packaging blocks 132.
FIG. 4 is a top view of the antenna package 100 of the invention. Each of the first, second and third dish has a central area 101 a major axis 102 and a minor axis 103. The major axis 102 is perpendicular to the minor axis 103. The first bracket 141, the second bracket 1442 and the third bracket 1443 correspond to the central area 101. The area of the central area 101 is substantially equal to one-third the area of the first, second or third dish. The first arm 151, the second arm 152, and the third arm 153 are parallel to the major axis 102 and correspond to the concave surface 121. The first bracket 141, the second bracket 142 and the third bracket 143, correspond to and face the concave surface 121.
FIG. 5 shows an assembled antenna package 100. The first packaging block 131 comprises a first surface 1311. Each of the second packaging blocks 132 comprises a second surface 1321.
