Abstract: A method is performed by an electronic device that includes antenna modules AM1 and AM2. The method includes: while transmitting or receiving through AM1, receiving a specified wireless signal through AM1 and AM2; identifying a first signal quality for the specified wireless signal of AM1 and a second signal quality for the specified wireless signal of AM2; and in response to determining that a difference between the first signal quality and the second signal quality is within a specified signal quality range and that a rank of a wireless channel through which the specified wireless signal is received is two or more, selecting an antenna module to transmit or receive a wireless signal, from among AM1 and AM2, based on first channel information about AM1 and second channel information about AM2. The method includes transmitting or receiving the wireless signal using the selected antenna module.

Abstract: Disclosed is an electronic device including an antenna module including a first antenna element and a second antenna element, and a processor operatively connected to the antenna module. The processor may be configured to transmit a first signal through the first antenna element, to receive a second signal including a signal obtained as the first signal is reflected by a target object, through the second antenna element, to calculate a distance from the antenna module to the target object based on a phase of the second signal, and to reduce a power level of the antenna module when the distance to the target object is smaller than a reference distance. In addition, various embodiments as understood from the specification are also possible.
