CONTROL METHOD AND APPARATUS FOR TERMINAL ANTENNA

WIPO Patent Application WO/2024/041044

A1

The present application provides a control method and apparatus for a terminal antenna. The method comprises: acquiring a real-time reflection coefficient of an antenna of a terminal device; according to a distance difference between the positions of the real-time reflection coefficient and a free space (FS) reflection coefficient of the antenna on a Smith chart, determining whether the antenna is in a human body use scenario; if the antenna is in the human body use scenario, determining whether a specific absorption rate (SAR) of the antenna is greater than or equal to a first preset threshold; if the SAR is greater than or equal to the first preset threshold, adjusting an adjustable device of the antenna to increase a reflection coefficient of a transmitting frequency band of the antenna, the adjustable device comprising a capacitor and/or an inductor.
