摘要： Presented is a combo antenna module for preventing shadowing of a short-range communication antenna by forming a loop pattern, for short-range communication, in an inner circumferential region of a wireless power transmission antenna. The presented combo antenna module comprises a radiation pattern for wireless power transmission and a radiation pattern for short-range communication, which are disposed on a base substrate, wherein the transverse paths for entry and exit are made different for the radiation pattern for short-range communication so as to form a loop pattern in the inner area of the radiation pattern for wireless power transmission.

摘要： 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.

摘要： Disclosed is a combo antenna module which can improve antenna performance by arranging a radiation pattern for electronic payment such that a portion of the radiation pattern does not overlap a magnetic sheet. The disclosed combo antenna module includes: a radiation pattern for wireless power transmission and a radiation pattern for electronic payment which are formed on a base substrate; and a magnetic sheet arranged to overlap the entire radiation pattern for wireless power transmission and a portion of the radiation pattern for electronic payment.
