Abstract

A touch screen panel (TSP) antenna of a mobile terminal is provided. The TSP antenna includes an ITO film stacked in a TSP, an upper electrode line, a lower electrode line, a left electrode line, and a right electrode line formed at an upper or lower surface of the ITO film, an external surface, and an antenna pattern formed in at least one of an upper surface, a lower surface, a left surface, and a right surface of the external surface.

Claims
