The present invention relates to a near-field antenna. In an aspect, the near-field antenna may include a dielectric layer, a ground plane formed on one side of the dielectric layer, a plurality of U-shaped slots periodically disposed in the ground plane for radiation, and a microstrip line provided on the other side of the dielectric layer for power feeding. In another aspect, the near-field antenna may include a dielectric layer, a ground plane formed on one side of the dielectric layer, a plurality of U-shaped slots periodically disposed in the ground plane for radiation, and a microstrip line configured to have a plurality of U-shaped slots diverged on the other side of the dielectric layer in parallel for power feeding, have the plurality of U-shaped slots periodically disposed in series in respective diverged lines, and have an end shorted to form standing waves.
