1. Technical Field
The present disclosure relates to an antenna module used in a portable electronic device.
2. Description of Related Art
Antennas are installed in portable electronic devices to send/receive wireless signals. Generally, the antennas may send/receive wireless signals of different frequencies (e.g., DCS1800, PCS1900, UMTS2100, etc.), requiring that the antennas be multiband antennas.
However, most conventional multiband antennas have complicated structures and are large, despite most current portable electronic devices being small with insufficient space to install the multiband antennas. Even if some miniaturized multiband antennas can be installed in the portable electronic devices, they are difficult to install with precision, and communication quality of the portable electronic devices may be affected.
Therefore, there is room for improvement within the art.
Many aspects of the antenna module can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the antenna module.
The portable electronic device 100 includes a cover 10, a housing 30 and a connector 50. The connector 50 is used to electronically connect the antenna module 200 to a printed circuit board 35 mounted on the housing 30. The connector 50 is a metal plate, and includes a main plate 52 and a finger end 54 at one end of the main plate 52.
The cover 10 includes an upper surface 11. A recessed portion 111 is defined in the upper surface 11. The recessed portion 111 respectively defines two grooves 115, one at each side thereof. A protrusion 113 is formed on the recessed portion 111.
Also, referring to
The antenna module 200 includes an antenna 90, a transparent film 80, and a holder 70. The holder 70 is the carrier of the antenna 90 and the transparent film 80.
The antenna 90 includes a feed portion 911, a first radiator 913 and a second radiator 915. The first radiator 913 and the second radiator 915 extend from the feed portion 911, but are separated from each other. The first radiator 913 and the second radiator 915 have different lengths to generate signals of different resonant frequencies in response to radio frequency signals fed in the feed portion 911. The feed portion 911 is U-shaped.
The holder 70 includes a first end portion 73, a second end portion 75 and a connecting portion 77 connecting with the first, second end portions 73, 75. The first end portion 73 and the second end portion 75 respectively define a first latching hole 731 and a second latching hole 751. A block 79 is positioned adjacent to the second end portion 75 allowing the U-shaped feed portion 911 mounted thereon. Two wedges 733 are respectively formed at two sides of the first end portion 73 for engaging with the grooves 115 of the cover 10.

Referring to
The main plate 52 of the connector 50 extends through the through hole 315, and then are bent to clip the housing 30. The main plate 52 is electronically connected to the printed circuit board 35, and the finger end 54 electronically connects to the feed portion 911 of the antenna 90. Thus, the antenna 90 electronically connects with the printed circuit board 35.
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
