摘要： Proposed is a combo antenna module which laminates a loop coil and an antenna sheet to configure a combo antenna, thereby preventing the degree of design freedom from being lowered and minimizing the manufacturing cost. The proposed combo antenna module includes a magnetic sheet, a loop coil disposed on the upper surface of the magnetic sheet, and an antenna sheet having the area smaller than that of the magnetic sheet, and disposed on the upper surface of the magnetic sheet, in which the antenna sheet overlaps a part of the loop coil.
