An electronic device is provided. The An electronic device comprises a near field communication (NFC) circuit for transmitting a set of near field communication differential signals including a first differential signal and a second differential signal; a housing including a conducting portion with a ground point, a first side and a second side opposite to the first side; and two conductive arms. A current loop is formed by the conductive arm and the conducting portion, and a potential of the ground point is equal to a median potential of the current loop.
