Abstract: According to an embodiment, an electronic device may include a first Printed Circuit Board (PCB). The first PCB may include a wireless communication circuit, a first connector which includes a first terminal and a second terminal, a first conductive path which couples the wireless communication circuit and the first terminal, a second conductive path which couples a first ground and the second terminal, a third conductive path which couples a Direct Current (DC) power source and the first conductive path, and at least one resistor and at least one first inductor coupled with the third conductive path. The electronic device may further include a second PCB electrically coupled with to at least one antenna. The second PCB may include a second connector which includes a third terminal and a fourth terminal, a fourth conductive path which couples the at least one antenna and the third terminal, a fifth conductive path which couples a second ground and the fourth terminal, at least one capacitor coupled with the fifth conductive path, a sixth conductive path which couples the second ground and the fourth conductive path, and at least one second inductor coupled with the sixth conductive path. The electronic device may further include a conductive member which includes a third connector capable of electrically coupling with the first connector and a fourth connector capable of electrically coupling with the second connector, and transfers a frequency signal between the wireless communication circuit and the at least one antenna, a processor electrically coupled with to the first PCB, and a memory operatively coupled with the processor. The memory may store instructions, when executed, causing the processor to couple with the third conductive path and detect, on the basis of a DC voltage input to the processor, a connecting issue between the first connector and the third connector or a connecting issue between the second connector and the fourth connector. Various other embodiments may be included.
