When the electronic device is currently in a state of holding the two-hand vertical screen, because the hand may interfere with the radiator antenna on the long-side frame, the antenna radiator on the short-side frame, that is, the third radiator and the fourth radiator, may be selected as the radio frequency transceiver antenna.
