Abstract: Disclosed is an electronic device is provided. The electronic device includes a first substrate, a second substrate arranged to be spaced apart from the first substrate, a first cable electrically connecting a first point on the first substrate and a second point on the second substrate, and a second cable electrically connecting a third point on the first substrate and a fourth point on the second substrate. The first substrate may include a first communication circuit, a second communication circuit, a detection circuit, a voltage application unit, and a ground unit, and a second substrate may include a first antenna, a first capacitive element, a second antenna, a second capacitive element, and an isolation circuit. The isolation circuit may isolate a radio frequency (RF) signal between the first path and the second path, and electrically connect the detection circuit to the ground unit through the first cable and the second cable.
