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.

Combo antenna module and portable device having same

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.

Combo antenna module

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.

Provided are a rear cover of a portable terminal, which is formed from a metallic material and is capable of operating as an auxiliary radiator of a near-field communication antenna pattern by forming slits thereon, and a portable terminal having the same. The provided rear cover is formed from a metallic material, has a slit part, allows a near-field communication antenna and the slit part to form an overlapping area when the rear cover is mounted on the rear surface of the portable terminal, and operates as the auxiliary radiator of the near-field communication antenna through the coupling of the near-field communication antenna and the slit part in the overlapping area.
