The invention relates to a signal transmission method and a signal transmission device, and the method comprises the steps: obtaining the scanning state of a camera disposed on a mobile terminal when a millimeter wave antenna transmits a millimeter wave signal, and enabling the scanning state to be used for indicating the shielding information of the camera; determining a target radio frequency transceiver for transmitting a radio frequency signal according to the scanning state of the camera; controlling the target radio frequency transceiver to transmit the radio frequency signal through the radio frequency transmitting path, and determining the target radio frequency transceiver transmitting the radio frequency signal according to the acquired scanning state of the camera, so that the mobile terminal can realize signal communication with the receiving equipment through the target radio frequency transceiver, and radiation of the radio frequency signal to a human body is reduced.
Description
technical field [0001] The present disclosure relates to the technical field of antennas, and in particular, to a signal transmission method and a signal transmission device. Background technique [0002] The millimeter-wave antenna is a carrier installed on the mobile terminal for radio frequency transmission. For example, the mobile terminal and the receiving device perform signal transmission and reception, and the millimeter-wave antenna can be used for signal transmission. [0003] However, when the millimeter-wave antenna transmits signals, if the radio frequency signal emitted by the millimeter-wave antenna passes through the human body, an induced electromagnetic field will be generated in the human body under the action of an external electromagnetic field, which will cause certain radiation damage to the human body. In order to avoid the radiation loss of the radio frequency signal emitted by the millimeter-wave antenna to the human body, it is necessary to add a d...
