Near field communication antenna device of mobile terminal

摘要

A near field communication antenna device of a mobile terminal having a near field communication antenna function of 13.56 MHz by Alternating Current (AC) coupling a conductive pattern of a touch screen panel is provided. The device includes a conductive pattern formed in a touch screen panel, a first antenna line AC-coupled to one end of the conductive pattern, a second antenna line AC-coupled to the other end of the conductive pattern, and a near field communication module connected to the first antenna line and the second antenna line. Therefore, a near field communication antenna can be embodied using a conductive pattern of an existing touch screen panel. Accordingly, an increase in thickness and material cost of a mobile terminal can be prevented.
