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.

Method for improving wireless communication performance and electronic device therefor

An electronic device according to an example embodiment includes: a substrate; and a connector including a plurality of terminals disposed on a first area of the substrate, wherein the substrate includes: a first layer including signal lines connected to the plurality of terminals and a dielectric material disposed between the signal lines; a second layer disposed on the first layer, and including a first ground electrically connected with the connector and a second ground physically isolated from the first ground; a third conductive layer disposed on the second layer, and electrically connected with the second ground; and a fourth layer having a nonconductive material disposed on an area corresponding to the first area between the second layer and the third conductive layer.
