Antenna component, terminal equipment and method for improving antenna radiation index

Abstract

The invention provides terminal equipment. The terminal equipment comprises an antenna assembly, a controller, an upper sensor and a lower sensor; the antenna assembly comprises an upper antenna, a lower antenna and a radio frequency transceiver; the upper antenna and the lower antenna are electrically connected with the radio frequency transceiver; the controller is also electrically connected with the radio frequency transceiver; the upper sensor is used for sensing a first distance between the upper antenna and a target object; the lower sensor is used for sensing a second distance betweenthe lower antenna and the target object; the controller is used for controlling the upper antenna to be in a disabled state and controlling the lower antenna to be in an enabled state when the first distance is less than the second distance; and the controller is used for controlling the upper antenna to be in an enabled state and controlling the lower antenna to be in a disabled state when the first distance is greater than the second distance. The invention further provides the antenna assembly and a method for improving antenna radiation performance. According to the terminal equipment provided by the invention, according to the distance between the target object and the upper antenna and the lower antenna, the upper antenna and the lower antenna are determined to be enabled or disabled, and the radiation stray is prevented from exceeding the standard on the premise of ensuring the communication quality.

Description

technical field [0001] The present application relates to an antenna structure of an electronic device, and in particular, to an antenna assembly that can improve the radiation performance of the antenna, a terminal device having the antenna assembly, and a method for improving the radiation index of the antenna. Background technique [0002] SAR (Specific Absorption Rate, specific absorption rate) is an indicator about the radiation of mobile phones and other electronic devices to the human body. It is currently the mandatory certification indicator for electronic devices, and it is the most complicated and difficult problem in all certifications. Under normal circumstances, when the human body is close to the antenna of the electronic device in the case of high power, its energy will be absorbed by the human body, causing the SAR value to exceed the standard and causing a potential safety hazard to the human body. [0003] For the test of SAR value, there are mainly two te...
