1. A combo antenna module comprising:
an antenna sheet on which a plurality of radiation patterns are formed;
a top magnetic sheet disposed on an upper surface of the antenna sheet, and disposed adjacent to a first side of the antenna sheet;
a bottom magnetic sheet disposed on a lower surface of the antenna sheet, and disposed adjacent to a second side of the antenna sheet opposite to the first side of the antenna sheet; and
an expansion magnetic sheet disposed on an upper surface of one of the top magnetic sheet and the antenna sheet, and disposed adjacent to the first side of the antenna sheet,
wherein the top magnetic sheet includes a first projecting region overlapping the bottom magnetic sheet with the antenna sheet interposed therebetween, and the top magnetic sheet and the bottom magnetic sheet are spaced apart from each other to have a gap interval within a set range at a side portion of the first projecting region, and
wherein the expansion magnetic sheet includes one or more expansion regions extending from an outer circumference of a region overlapping the antenna sheet and disposed outside the antenna sheet.
