Abstract

An electronic device may include: at least one processor; memory storing instructions; a housing including a support; a conductive portion; a printed circuit board (PCB) providing a first ground; an electronic component providing a second ground; a switch circuit configured to electrically connect the conductive portion to the ground layer of the PCB or the electronic component; and wireless communication circuitry configured to communicate with an external electronic device through the conductive portion. The instructions, when executed by the at least one processor individually or collectively, may cause the electronic device to: control the switch circuit, when the wireless communication circuitry transmits a signal on a first frequency band, to electrically connect the conductive portion to the PCB, and control the switch circuit, when the wireless communication circuitry transmits a signal on a second frequency band, to electrically connect the conductive portion to the electronic component.
