Abstract: Herein disclosed is a surface-mounted NFC antenna, having a small size and good performance, comprising a magnetic core, a first dielectric layer, a first coil and a second coil. The first coil is wound on the outer surface of the magnetic core. One side of the first dielectric layer, away from the magnetic core, is the first surface. The second coil is disposed on the first surface. The tail end of the first coil is electrically connected with the head end of the second coil. In the NFC antenna, the second coil is disposed on the dielectric layer to separate the first coil from the second coil, thereby preventing the magnetic field generated by the first coil from weakening the magnetic field generated by the second coil, so the magnetic field generated by the second coil is relatively larger.

Abstract: A shield structure includes a shield bracket, a shield cover, and a shield layer. The shield cover is formed with openings. The shield layer is spliced with the shield cover through a conductive tape layer and covers all openings. The shield cover is formed with openings and a light shield layer is spliced with the shield cover and covers the openings, greatly reducing the weight of the shield cover while ensuring the shielding effect, without compressing space for other elements. The shield layer is thin, capable of lowering down the shield, dissipating heat effectively, reducing the temperature of the whole machine and providing a good environment for the operation of the whole machine, without affecting the shielding effect; and the conductive tape layer is spliced with the shield layer, thus allowing multiple assembling without damaging the whole structure, and facilitating subsequent repair.
