Electronic device for performing antenna tuning and method of operating the same

Abstract

According to an embodiment, an electronic device may include memory storing instructions, a plurality of antennas including a first antenna configured to transmit and receive radio frequency (RF) signals corresponding to a first radio access technology (RAT) and a second RAT, and a second antenna configured to receive RF signals corresponding to the first RAT and the second RAT, an RF circuit coupled to the plurality of antennas, and at least one communication processor, comprising processing circuitry, operatively coupled to the memory and the RF circuit. The instructions, when executed by at least one communication processor, individually and/or collectively, may cause the electronic device to: establish a first transmission channel connection based on the first RAT and a second transmission channel connection based on the second RAT using one of the plurality of antennas, identify whether a voice call based on the first RAT is executed, and operate in a first antenna tuning mode, based on an electric field based on the first RAT being equal to or greater than a first value, and operate in a second antenna tuning mode, based on the electric field based on the first RAT being less than the first value, during execution of the voice call. Based on the first antenna tuning mode being switched to the second antenna tuning mode according to a change in the electric field, a parameter associated with antenna sensitivity of the second transmission channel connection based on the second RAT may decrease.
