Abstract
Disclosed is an antenna module for near field communication, which stacks laminates on which a vertical winding radiation pattern and a horizontal winding radiation pattern are formed, respectively, thereby improving communication performance on the side surface and one surface of a portable terminal while minimizing a mounting space. The disclosed antenna module for near field communication includes a first magnetic member; a vertical winding radiation pattern winding the outer circumference of the first magnetic member; a second magnetic member stacked on the lower surface of the first magnetic member; a horizontal winding radiation pattern formed on one surface of the second magnetic member; a dielectric stacked on the lower surface of the second magnetic member; and a terminal portion formed on the dielectric to be connected to at least one of the vertical winding radiation pattern and the horizontal winding radiation pattern.
