1. Technical Field
The present disclosure relates to electronic devices, particularly, to an electronic device with a structure for enhancing its antenna performance.
2. Description of Related Art
Electronic devices, such as mobile phones, digital photo frames, and electronic readers, are usually equipped with an antenna, and a display panel, such as liquid crystal display panel, or an LED panel. As shown in
An electronic device with structure for enhancing antenna performance to overcome the described limitations is thus needed.
Many aspects of the present disclosure are 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 present disclosure.
Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiments of the present disclosure will be described, with reference to the accompanying drawings.
Referring to
In the embodiment, the electronic device 1 also includes three conductive patches 30. Two of the three conductive patches 30 are located on the first side 101 of the metal plate 10, and are electrically contacted with both of the metal plate 10 and the metal strips 20 contacted to the first side 101. The other conductive patch 30 is located on the second side 102 of the metal plate 10 paralleled to the first side 101, and is electrically contacted with both of the metal plate 10 and the metal strips 20 contacted to the second side 101. The three conductive patches 30 form three conductive points between the metal plate 10 and the corresponding conductive strips 20 as shown in
Therefore, The surface current flowing through the metal plate 10 and the conductive strips 20 produced due to the electronic device 1 is started up or in the process of communication is interfered, and the magnetic field produced by the annular protrusion portions 201 is reduced. Thus the SAR and the intensities of electromagnetic radiation are reduced.
In the embodiment, the shape of the conductive patches 30 can be rectangle, round, triangle, and the size of the conductive patches 30 are much smaller than the size of the metal plate 10.
In the embodiment, the electronic device 1 also includes a strip-shaped conductive patch 40. The strip-shaped conductive patch 40 is located on the metal plate 10 and is paralleled to the third side 103 of the metal plate 10. The strip-shaped conductive patch 40 is electrically contacted with both of the metal plate 10 and the metal strips 20 contacted to the third side 103. In the embodiment, the length of the strip-shaped conductive patch 40 is equal to the length of the third side 103 of the metal plate 10. The strip-shaped conductive patch 40 makes the metal strips 20 contacted to the third side 103 be completely contacted to the metal plate 10. Therefore, the gaps between the metal plate 10 and the metal strips 20 are decreased, thus enhancing the antenna performance In the embodiment, the conductive patches 30 and the strip-shaped conductive patch 40 can be made of copper, iron, aluminum, silver or other metal.
As shown in
In the embodiment, the electronic device 1 can be a mobile phone, a personal digital assistant, an electronic reader, or a digital photo frame, which includes the display panel and with the communication function.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments of the present disclosure.
