Abstract: Various examples of the present invention relate to a device and a method for improving wireless communication performance in an electronic device. The electronic device comprises multiple antennas, a communication circuit connected to the multiple antennas, a connector, and at least one processor, wherein the processor checks whether a wired cable is connected through the connector and, if the wired cable is connected through the connector, can perform control such that communication using the multiple antennas corresponding to the connection of the wired cable is performed. Other examples can be possible.
