Abstract
A near field communication (NFC) antenna includes a first antenna electrode and a second antenna electrode, and a loop coil. The first and second antenna electrodes are formed on a first surface of a substrate. The loop coil is formed on the first surface of the substrate, is directly coupled between the first antenna electrode and the second antenna electrode, and includes a first plurality of turns. The first antenna electrode is located inside each of the plurality of turns of the loop coil, and the second antenna electrode is located outside each of the plurality of turns of the loop coil. An imaginary line passing through the first antenna electrode and the second antenna electrode is parallel to one of edges of the substrate. Each of the first plurality of turns of the loop coil does not overlap each other.
