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.

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 and a method for manufacturing the same, in which a combo antenna of a low frequency band and an antenna of a high frequency band are integrated to minimize the mounting space and thickness while maintaining the same level of antenna performance. The disclosed combo antenna module comprises: a first antenna in which a first antenna pattern having a first operation frequency is disposed, and an attachment area not overlapping with the first antenna pattern is defined; and a second antenna which is disposed in the attachment area and has a second antenna pattern having a second operation frequency higher than the first operation frequency and disposed on the upper surface thereof, wherein the dielectric loss value of the second antenna is lower than the dielectric loss value of the first antenna.

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.
