Title:
ADJUSTMENT METHOD FOR SPECIFIC ABSORPTION RATIO, AND ANTENNA APPARATUS, TERMINAL DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/160151
Kind Code:
A1
Abstract:
Disclosed in the present application are an adjustment method for a specific absorption ratio, and an antenna apparatus, a terminal device and a storage medium. The adjustment method comprises: acquiring an average specific absorption ratio of any radiation point in a radiation pattern; and when it is detected that the average specific absorption ratio of any radiation point is greater than or equal to a preset threshold value, controlling an antenna tuner 110 to switch a working mode. Therefore, the radiation pattern of an antenna is adjusted, so as to change the position of the radiation point with the highest specific absorption ratio in the radiation pattern, such that the specific absorption ratio of the any radiation point is reduced, thereby reducing the average specific absorption ratio of the any radiation point; and the average specific absorption ratio can be controlled to be less than a standard value without reducing the radio-frequency power of a terminal device 300, thereby improving the communication performance of the terminal device 300 while reducing an SAR value.
