    摘要： According to various embodiments disclosed herein, an electronic device includes a transceiver configured to generate a first signal and a second signal, a first coupler configured to receive the first signal from the transceiver and provide the first signal to the first antenna; a second coupler configured to receive the second signal from the transceiver and provide the second signal to the second antenna; and a control circuitry operatively connected to the transceiver. The control circuitry is configured to determine values associated with a phase difference between the first signal and the second signal at least partially based on the signals from the first coupler and the second coupler, and to cause the transceiver to adjust a phase of the first signal and/or a phase of the second signal using at least some of the values in order to reduce or remove the phase difference. Other embodiments have been provided.

    摘要： An electronic device is provided. The electronic device includes a first antenna configured to transmit a first transmission signal having a first phase, a second antenna configured to transmit a second transmission signal having a second phase, a transceiver electrically connected to the first antenna and the second antenna, and a processor. The transceiver is configured to identify a first feedback transmission signal including part of the first transmission signal and a second feedback transmission signal including part of the second transmission signal and calculate a correlation for the first and second feedback transmission signals. The processor is configured to predict radiation power radiated from the electronic device based on at least the part of the correlation, control the transceiver to adjust at least one of the first phase or the second phase, and change the predicted radiation power to a predetermined value based on an operation for the adjustment.
