1. An antenna control method, for an electronic device, the electronic device comprising one first antenna for radiating first antenna signals and a plurality of second antennas for radiating second antenna signals, the method comprising:
establishing a plurality of antenna combinations capable of radiating the first antenna signals and the second antenna signals simultaneously, wherein each of the plurality of antenna combinations comprises a first antenna and one of the plurality of second antennas;
for each of the plurality of antenna combinations, obtaining, in response to the first antenna and the one of the plurality of second antennas radiating the first antenna signals and the second antenna signals simultaneously, a combination electromagnetic wave specific absorption rate (SAR) of each of the plurality of antenna combinations;
obtaining a plurality of predetermined antenna combinations of which combination electromagnetic wave SARs meet a predetermined condition;
obtaining a target antenna combination according to the plurality of predetermined antenna combinations;
obtaining, in response to the electronic device radiating the first antenna signals and the second antenna signals simultaneously, a combination electromagnetic wave SAR of the first antenna and one of the plurality of second antennas in an operating state;
calling, in response to the combination electromagnetic wave SAR not meeting a predetermined condition, the target antenna combination including a first target antenna and a second target antenna; and
controlling the first target antenna and the second target antenna to be in the operating state for radiating the first antenna signals and the second antenna signals simultaneously.
