Abstract
Suggested is a combo antenna module configured to implement the same antenna performance as that of a combo antenna module having a general size, even in a state in which the size thereof is reduced by adjusting, within a set range, a distance at which magnetic sheets disposed on the top and the bottom of an antenna sheet are spaced apart. The suggested combo antenna module comprises: an antenna sheet; a top magnetic sheet disposed on the upper surface of the antenna sheet; and a bottom magnetic sheet disposed on the lower surface of the antenna sheet, wherein the top magnetic sheet includes a projecting region which overlaps with the bottom magnetic sheet while having the antenna sheet therebetween, and the top magnetic sheet and the bottom magnetic sheet are spaced apart at a distance within a set range at a side portion of the projecting region.
