Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them.

[0026] In the antenna device according to an embodiment of the present invention, there are two antenna units. When the performance of one antenna unit deteriorates, a switching unit is used to replace the radiation part of the other antenna unit with the radiation part of the antenna unit whose performance deteriorates to transmit signal to improve its performance, so that the antenna performance of the second antenna unit in the electronic device can be guaranteed conveniently and effectively without adding additional components, so as to improve the communication quality.

[0027] The antenna device and the control method for the antenna device accordi...

Abstract

The invention provides an antenna device, electronic equipment comprising the antenna device, and a method for controlling the antenna device. The antenna device comprises a first antenna unit, a second antenna unit, a detection unit and a switching unit, wherein the first antenna unit is provided with a first radiation part and used for transmitting a first antenna signal with a first frequency band; the second antenna unit is provided with a second radiation part and used for transmitting a second antenna signal with a second frequency band; the second frequency band is different from the first frequency band; the detection unit is used for detecting a working state of the second antenna unit; and the switching unit is used for coupling the first radiation part with the second antenna unit when the working state is under a specific condition, so that the second antenna unit uses the first radiation part to transmit the second antenna signal. According to the technical scheme of all embodiments of the invention, the performance of a certain antenna in the electronic equipment can be ensured conveniently, quickly and effectively to improve the communication quality.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to an antenna device, an electronic device including the antenna device and a method for controlling the antenna device. Background technique [0002] With the development of communication technology, various electronic devices can use antennas to transmit and / or receive data, thus greatly facilitating the transmission of information and data. Frequency resources of each frequency band are standardized for wireless communication. For example, the 76MHz-108MHz frequency band is used to transmit FM signals; the 400MHz-798MHz frequency band is used to transmit broadcast TV signals; the 890MHz-954MHz frequency band is used to transmit GSM signals of the Global System for Mobile Communications (GSM, Global System for Mobile Communications) ; The 1710-1830MHz frequency band is used to transmit DSG signals of the digital cellular system (DCS, Digital Cellular System) and so on. ...
