Abstract
A near field communication (NFC) antenna including a dielectric substrate, a coil, and a coupling structure is provided. The coil is disposed on the dielectric substrate. The coupling structure includes at least one coupling branch. Two ends of the coupling branch are respectively connected to two different connection points on the coil. The coupling structure is configured to improve the isotropic characteristics of the NFC antenna.
