Abstract

A circuit board includes an antenna substrate and a main substrate. The antenna substrate has at least one first linking portion. The main substrate has at least one second linking portion. The first linking portion connects with the second portion so that the antenna substrate assembles with the main substrate. Herein, the antenna is substantially perpendicular to the main substrate.

Claims

1. A circuit board, comprising:

an antenna substrate having at least one first linking portion; and

a main substrate having at least one second linking portion, wherein the first linking portion connects to the second linking portion so that the antenna substrate and the main substrate are assembled, and the antenna substrate is substantially perpendicular to the main substrate.

2. The circuit board of claim 1, wherein the first linking portion is a T-shaped protruding portion with a neck part and an end part.

3. The circuit board of claim 2, wherein the second linking portion is a hole, so that when the first linking portion connects to the second linking portion, the protruding portion is engaged with the hole.

4. The circuit board of claim 3, wherein the second linking portion is an H-shaped hole.

5. The circuit board of claim 2, wherein the height of the neck part is substantially equal to the thickness of the main substrate.

6. The circuit board of claim 1, wherein the first linking portion is an L-shaped hook.

7. The circuit board of claim 6, wherein the second linking portion is a hole, so that the hook goes through the hole and then engages with the hole so as to connect the first linking portion to the second linking portion.

8. The circuit board of claim 1, wherein the antenna substrate has at least one first signal terminal, the main substrate has at least one second signal terminal, and the first signal terminal is electrically coupled to the second signal terminal when the antenna substrate and the main substrate are assembled.

9. The circuit board of claim 1, wherein the antenna substrate has an antenna unit.

10. The circuit board of claim 1, wherein the first linking portion is a hole.

11. The circuit board of claim 10, wherein the first linking portion is an H-shaped hole.

12. The circuit board of claim 10, wherein the second linking portion is a T-shaped protruding portion with a neck part and an end part, so that when the first linking portion connects to the second linking portion, the protruding part is engaged with the hole.

13. The circuit board of claim 12, wherein the height of the neck part is substantially equal to the thickness of the main substrate.

14. The circuit board of claim 10, wherein the second linking portion is an L-shaped hook, so that the hook goes through the hole and then engages with the hole so as to connect the first linking portion to the second linking portion.

15. The circuit board of claim 1, wherein each of the first linking portion and the second linking portion is a T-shaped protruding portion with a neck part and an end part, so that when the first linking portion connects to the second linking portion, the protruding portions are engaged with each other.

16. The circuit board of claim 1, wherein each of the first linking portion and the second linking portion is a L-shaped hook, so that when the first linking portion connects to the second linking portion, the hooks are engaged with each other.

17. The circuit board of claim 1, further comprising a fixing element for fastening the antenna substrate on the main substrate.

18. The circuit board of claim 17, wherein the fixing element is disposed adjacent to the antenna substrate and is fixed on the main substrate.
