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.
