Abstract

An electronic apparatus includes a casing, at least an antenna body, a feeding point and a control unit. The casing has a display portion. The antenna body is disposed at the casing and at least has two radiation paths and a switching element. Parts of the radiation paths are respectively disposed at two sides of the display portion. The switching element is electrically connected with the radiation paths. The feeding point is electrically connected with the switching element and operationally connected to one of the radiation paths. The control unit controls the switching element based on the rotation of the electronic apparatus. When one of the radiation paths is located between a user and the display portion, the control unit controls to selectively switch the switching element for connecting the other radiation path to the feeding point.

Claims

1. An electronic apparatus, comprising:

a casing having a display portion;

at least an antenna body disposed at the casing and at least having two radiation paths and a switching element, wherein parts of the radiation paths are respectively disposed at two sides of the display portion, and the switching element is electrically connected with the radiation paths;

a feeding point electrically connected with the switching element for operationally connect to one of the radiation paths; and

a control unit controlling the switching element based on a rotation of the electronic apparatus, wherein when one of the radiation paths is located between a user and the display portion, the control unit controls to selectively switch the switching element for connecting the other one of the radiation paths to the feeding point.

2. The electronic apparatus of claim 1, wherein the radiation paths are disposed at two adjacent sides or two opposite sides of the electronic apparatus respectively.

3. The electronic apparatus of claim 1, further comprising an orientation sensor for sensing the rotation of the electronic apparatus and outputting a control signal to the control unit for controlling the switch element.

4. The electronic apparatus of claim 1, wherein the electronic apparatus performs communication through WWAN (Wireless Wide Area Network), LTE (Long Term Evolution), or WIMAX (Worldwide Interoperability for Microwave Access).

5. The electronic apparatus of claim 1, wherein when the electronic apparatus comprises two antenna bodies, the antenna bodies are disposed at a left side and a right side of the electronic apparatus respectively.

6. The electronic apparatus of claim 1, wherein the electronic apparatus is a touch-control mobile phone, a touch-control computer, or a GPS.
