Abstract
An electronic device according to a disclosed embodiment includes a first antenna, a second antenna, a first communication circuit configured to communicate in a first frequency band with the first antenna at a first data rate, a second communication circuit configured to communicate in a second frequency band with the second antenna at a second data rate, a first coupler electrically connected between the first antenna and the first communication circuit, and at least one communication circuit configured to control to identify, during at least part of a period of simultaneously transmitting a first transmit signal with the first antenna and a second transmit signal with the second antenna, an amplitude of a first receive signal including at least part of the second transmit signal detected by the first coupler, disable an operation of attenuating the at least part of the second transmit signal included in the first receive signal based on the amplitude of the first receive signal falling in a first designated range, and enable the operation of attenuating the at least part of the second transmit signal included in the first receive signal based on the amplitude of the first receiv…
