Due to the location of the second radiator 221 , when the electronic device 1 is used in a vertical screen, the second radiator 221 is far from the user's head, so the performance of the electronic device 1 is absorbed by electromagnetic wave energy. A test card (also referred to as a Tx white card) for performance detection of a ratio (Specific Absorption Rate, SAR) can be disposed adjacent to the second radiator 221, which can reduce the SAR value radiated to the user. The electromagnetic wave energy absorption ratio, also known as the specific absorption rate, refers to the electromagnetic wave power absorbed or consumed by a unit mass of human tissue, and the unit is W/Kg. The larger the SAR value, the more electromagnetic wave power absorbed or consumed per unit mass of human tissue, and the greater the harm to the human body; correspondingly, the smaller the SAR value, the more electromagnetic waves absorbed or consumed per unit mass of human tissue. The smaller the power, the less harmful it is to the human body.

When the signal strength difference between the first antenna 210 and the second antenna 220 is less than a preset strength difference, or the power amplifier 215 is electrically connected to the first radiator 211 and the transmit power of the power amplifier 215 is greater than the preset power When , it is determined that the performance of the first antenna 210 is not good. When the transmitting performance of the first antenna 210 is not good, the controller 610 uses the second antenna 220 as the transmitting antenna currently transmitting the electromagnetic wave signal of the first frequency band. In other words, the controller 610 switches the antenna for transmitting the electromagnetic wave signal of the first frequency band from the first antenna 210 to the second antenna 220 . For example, the controller 610 can control the transmitting antenna of the electromagnetic wave signal of the first frequency band by controlling the switch 620 (DPDT).

When the first antenna 210 is blocked, and the intensity of the electromagnetic wave signal of the first frequency band radiated by the first radiator 211 is weak, the controller 610 controls the power amplifier 215 to increase the transmit power. If the transmit power of the power amplifier 215 is greater than the preset power, it indicates that the first antenna 210 is severely blocked. Then, when the power amplifier 215 is electrically connected to the first radiator 211 and the transmit power of the power amplifier 215 is greater than the preset power, the controller 610 controls the switch to switch the The radio frequency front-end module 214 is electrically connected to the second radiator 221, so that the second antenna 220 is used as a transmitting antenna that currently transmits the electromagnetic wave signal of the first frequency band.
