摘要： An NFC antenna includes a first metal back cover and an antenna coil located on the inner side of the first metal back cover, a through-hole and a first slit are formed in the first metal back cover, the first slit is connected with one edge of the through-hole and one edge of the first metal back cover, the antenna coil surrounds the through-hole and the first slit, and one part of the antenna coil does not coincide with the first metal back cover and is not intersected with the first slit. Through the above manner, the effect of optimally changing the flow direction distribution and intensity of eddy currents can be achieved, the eddy current loops are used to enhance the performance of the antenna, and the shielding effect of the metal back is eliminated.
