ELECTRONIC DEVICE AND METHOD OF CONTROLLING POWER IN ELECTRONIC DEVICE

An electronic device includes a housing; a first antenna located at a first part of the housing; a second antenna located at a second part separated from the first part of the housing; a transceiver configured to generate a first signal and a second signal; a first coupler electrically connected between the first antenna and the transceiver and configured to receive the first signal from the transceiver and provide the received first signal to the first antenna; a second coupler electrically connected to the second antenna and the transceiver and configured to receive the second signal from the transceiver and provide the received second signal to the second antenna; and a control circuit operationally connected to the transceiver, wherein the control circuit is configured to determine at least one value related to gains of the first signal and the second signal based at least partially on the signals provided from the first coupler and the second coupler, determine whether the first signal has a higher gain than that of the second signal, and allow the first signal to have increased transmission power and the second signal to have reduced transmission power based at least partially on the at least one value related to the gains.
