Abstract
A portable electronic device with an NFC antenna comprises a touch screen and a first printed circuit board arranged on the back side of the touch screen. The touch screen comprises a touch area and a non-touch area surrounding the touch area. The upper surface of the first printed circuit board, corresponding to the non-touch area of the touch screen, is imprinted with an NFC antenna and a touch-sensitive circuit side by side. The lower surface of the first circuit board, corresponding to the NFC antenna, is equipped with a shielding layer so as to isolate the NFC antenna from other components arranged below the first circuit board. According to the electronic device, the NFC antenna and the touch-sensitive circuit are printed on the circuit board side by side and are correspondingly adhered to the non-touch area of the touch screen. Thus, the NFC antenna keeps away from a main circuit board of the electronic device; the influence of components on the main circuit board on performance of the NFC antenna is avoided; the space occupied by the NFC antenna in the electronic device is saved; and then the electronic device is allowed to have a thin size.
