Abstract: Various embodiments of the present invention relate to an electronic device having a noise blocking structure comprising: a first electronic component including a noise source; a first connecting portion disposed on one side of the noise source and grounded to a first grounded portion; and a second connecting portion disposed on the other side (such that the noise source is between the second connecting portion and the first connecting portion) and grounded to a second grounded portion. By means of a first grounded region formed by the first connecting portion and a second grounded region formed by the second connecting portion, the noise generated from the noise source is prevented from emanating at least to a second electronic component nearby so as to prevent a degradation in the performance of nearby electronic components.

Abstract: 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.
