Antenna device and method for controlling antenna device

Abstract

The invention provides an antenna device applied to electronic equipment and a controlling method thereof. The antenna device comprises a main antenna unit, an auxiliary antenna unit, a detection unit and a selection unit, wherein the main antenna unit is located at the first position of the electronic equipment and is used for transmitting signals of frequency bandwidths including the first frequency band; the auxiliary antenna unit is located at the second position, different from the first position, of the electronic equipment and is used for transmitting signals of the first frequency band; the detection unit is used for detecting parameters of signals transmitted by using the antenna device to obtain a detection result; and the selection unit is used for selecting the antenna unit in the antenna device for transmitting signals according to the detection result. When the technical scheme of the embodiment is used, antenna performances of the antenna device in the electronic equipment can be ensured even if the surrounding environment of the electronic equipment is changed.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly, to an antenna device and a method for controlling the antenna device. Background technique [0002] With the development of mobile communication technology, various types of electronic devices with communication functions appear, such as computers, personal digital assistants, mobile communication terminals, and the like. The electronic device has an antenna to transmit information and data and the like. When an antenna is arranged in an electronic device, the antenna is generally arranged comprehensively in combination with components such as a circuit board, a battery, and a stiffener of the electronic device, so as to avoid the influence of other components of the electronic device on the antenna to obtain good antenna performance. [0003] During the use of the electronic device, the surrounding environment is likely to interfere with the performance of ...

Problems solved by technology

However, this only compensates for the degradation of the antenna performance due to the frequency shift, and cannot compensate for the degradation of the antenna performance due to the absorption of electromagnetic waves

In this way, when it is affected by the surrounding environment such as hand holding and human body occlusion, it is difficult to obtain good antenna performance even with compensation
