Abstract

An integrated antenna for mobile communications. A short-circuiting metal cylinder is provided in the antenna for arranging other functional modules such that the antenna and related circuits may have better integration. The provided antenna includes a ground with a via-hole; a radiating member arranged on the ground and having a feeding portion for receiving signals via electrical connection through the via-hole; and a short-circuiting member having a space, a first end of which is electrically connected to the ground substantially vertically, and the other end of which is electrically connected to the radiating member. The radiating member further includes a first sub-radiating member, a second sub-radiating member and a third sub-radiating member. The first sub-radiating member is substantially triangular, and the second sub-radiating portion is substantially parallel to the ground. The third sub-radiating member is substantially parallel to the first sub-radiating member.

Claims

1. An integrated mobile communication antenna, comprising:

a ground having a via-hole;

a radiating member located above the ground having a feeding portion to electrically connect to a signal source through the via-hole to receive a signal, and having a housing opening; and

a short-circuiting member having a space and a lower opening on a first end, said short-circuiting member being substantially vertical to the ground and electrically connected to the ground, and a second end of said short-circuiting member being electrically connected to the radiating member, and the second end of the short-circuiting member having an upper opening corresponding to the housing opening of the radiating member with the same size and shape so that a functional module can be fully exposed;

wherein the space houses a functional module which is integrated with the antenna.

2. The integrated mobile communication antenna of claim 1, wherein the ground is substantially rectangular.

3. The integrated mobile communication antenna of claim 1, wherein the radiating member further includes:

a first sub-radiating member formed substantially in triangular having a top point and a bottom edge opposing the top point, the feeding portion being located on the top point;

a second sub-radiating member substantially in parallel with the ground having a first edge and a second edge that oppose each other, the first edge being electrically connected to the bottom edge; and

a third sub-radiating member substantially in parallel with the first sub-radiating member having a third edge electrically connected to the second edge.

4. The integrated mobile communication antenna of claim 3, wherein the first sub-radiating member, the second sub-radiating member and the third sub-radiating member are formed of a metal sheet by bending.

5. The integrated mobile communication antenna of claim 3, wherein the first sub-radiating member, the second sub-radiating member and the third sub-radiating member are formed of at least two independent metal sheets.

6. The integrated mobile communication antenna of claim 3, wherein the first sub-radiating member and the second sub-radiating member are electrically connected through an arched bending.

7. The integrated mobile communication antenna of claim 3, wherein the second sub-radiating member and the third sub-radiating member are electrically connected through an arched bending.

8. The integrated mobile communication antenna of claim 1, wherein the short-circuiting member has an upper opening on the second end connecting to the radiating member.

9. The integrated mobile communication antenna of claim 8, wherein the radiating member has an opening formed in a size and a shape mating the upper opening for connecting to the short-circuiting member.

10. The integrated mobile communication antenna of claim 1, wherein the short-circuiting member is formed in a shape selected from the group consisting of a circle, an ellipse, a rectangle and a polygon.

11. The integrated mobile communication antenna of claim 1, wherein the feeding portion further includes a feeding member which runs though the via-hole to receive the signal from the signal source.

12. The integrated mobile communication antenna of claim 1, wherein the lower opening and the upper opening of the short-circuiting member are the same size and shape.
