Abstract

The present invention discloses a mobile communication antenna device. The device includes: a monopole antenna, placed on one side of a printed circuit board, where a distance between the monopole antenna and a central position of the printed circuit board is less than a threshold, and the monopole antenna includes a first metal sheet which is vertical to the printed circuit board, and is conducted with a circuit of the printed circuit board through a feedpoint. The present invention also discloses a mobile communication terminal device. By adopting the present invention, an ultra wideband antenna may be achieved, thereby making it possible that a mobile communication terminal device product, such as a fixed station, supports more frequency bands.

First claim

What is claimed is:

1. A mobile communication antenna device, comprising:
a monopole antenna, placed on one side of a printed circuit board, wherein a distance between the monopole antenna and a central position of the printed circuit board is less than a threshold,
the monopole antenna includes:
a first metal sheet, vertical to the printed circuit board, and conducted through a feedpoint with a circuit of the printed circuit board,
a second metal sheet, placed between the printed circuit board and the first metal sheet, and vertical to the printed circuit board, wherein one side of the second metal sheet that is parallel with the first metal sheet is closer to the printed circuit board and is conducted with a ground point of the printed circuit board than another side of the second metal sheet that is parallel to the first metal sheet and is hanged in air.

2. The mobile communication antenna device according to claim 1 , wherein one side that is of the first metal sheet and is vertical to the printed circuit board is placed in a folded manner or disposed to form multiple serpentine grooves.

3. The mobile communication antenna device according to claim 2 , wherein the one side that is of the second metal sheet and is vertical to the printed circuit board is placed in a folded manner or disposed to form multiple serpentine grooves.

4. The mobile communication antenna device according to claim 2 , wherein a length and a width of a gap between the first metal sheet and the second metal sheet are adjustable according to wireless performance required by the mobile communication antenna device.

5. The mobile communication antenna device according to claim 2 , wherein a length and a width of a gap between the second metal sheet and the printed circuit board are adjustable according to wireless performance required by the mobile communication antenna device.

6. The mobile communication antenna device according to claim 1 , wherein the threshold is configured so the monopole antenna is approximately placed in the central position of the printed circuit board where distances between the monopole antenna and sides of the printed circuit board are substantially same.

7. The mobile communication antenna device according to claim 1 , wherein the one side that is of the second metal sheet and is vertical to the printed circuit board is placed in a folded manner or disposed to form multiple serpentine grooves.

8. The mobile communication antenna device according to claim 1 , wherein a length and a width of a gap between the first metal sheet and the second metal sheet are adjustable according to wireless performance required by the mobile communication antenna device.

9. The mobile communication antenna device according to claim 1 , wherein a length and a width of a gap between the second metal sheet and the printed circuit board are adjustable according to wireless performance required by the mobile communication antenna device.

10. A mobile communication terminal device, comprising a mobile communication antenna device according to claim 1 .
