Abstract

An antenna module (20) including an antenna holder (21) and an antenna set (40) is provided. The antenna holder includes a top surface (24) and an external end surface (22). The external end surface includes an upper edge (22a) adjacent to the top surface and a lower edge (22b). The antenna set includes a first antenna (42) and a second antenna (44). The second antenna is longer than the first antenna and is mounted on an upper edge of the external end surface. The second antenna includes a main section (444) mounted on a lower edge of the external end surface, a bent section (446) extending from the main section and is mounted on both the up and the lower edges of the external end surface, and an end section (448) extending from the bent section and is mounted on the top surface of the antenna holder.

Claims

1. An antenna module, comprising:

an antenna holder comprising a top surface and an external end surface, the external end surface comprises an upper edge adjacent to the top surface and a lower edge;

an antenna set comprising a first antenna and a second antenna, the second antenna being longer than the first antenna and being mounted on an upper edge of the external end surface; and

the second antenna comprises a main section mounted on a lower edge of the external end surface, a bent section extending from the main section and is mounted on both the up and the lower edges of the external end surface, and an end section extending from the bent section and is mounted on the top surface of the of the antenna holder.

2. The antenna module as claimed in claim 1, wherein the second antenna further comprises a front section, which is mounted on both upper and lower edges of the external end surface as a meandering-line structure.

3. The antenna module as claimed in claim 2, wherein the external end surface comprises a middle portion opposite to the internal end surface and a pair of side portions connected to the middle portion, the main portion extends from the front section and is mainly mounted on the middle portion.

4. The antenna module as claimed in claim 1, wherein the distance between the main section of the second antenna and the first antenna equals a thickness of the antenna holder.

5. The antenna module as claimed in claim 1, wherein the bent section further comprises a first bent portion and a second bent portion, the first bent portion extends from the main section and is bent upwardly, and the second bent portion extends from the first bent portion and is bent in a further direction of the first antenna so that it is mounted on the upper edge of the external end surface.

6. The antenna module as claimed in claim 1, wherein the first antenna is a high frequency antenna and the second antenna is a low frequency antenna.

7. The antenna module as claimed in claim 1, wherein the antenna set further comprises a feed point and a ground arranged on the top surface of the antenna holder.

8. A portable electronic device, comprising a flip cover and a main body connected to the flip cover via a hinge, the main body comprising a printed circuit board and an antenna module electrically connected to the print circuit board, wherein the antenna module comprising:
