The third layer 1030 may reduce the electrical influence of noise on the second coil (②). For example, the third layer 1030 may reduce or shield the noise so that the noise from the periphery of the second coil (②) does not affect the second coil (②). For example, in the third layer 1030 , noise from the inside of the electronic device 20 (eg, the first flexible printed circuit board 610 or the second printed circuit board 64 ) is generated by the second coil (②). ) can be reduced or shielded so as not to affect the noise. When the second coil (②) transmits or receives a signal passing through the second rear cover 221 of FIG. 6 from the outside, due to noise shielding by the third layer 1030, its radiation performance is reduced can be secured. According to one embodiment, the third layer 1030 may allow the magnetic flux formed from the second coil ② to be formed substantially toward the sixth surface 206 of FIG. 3 rather than toward the fifth surface 206 of FIG. there is.

According to one embodiment, the first flexible printed circuit board 610 may be positioned between the second layer 1020 and the second battery 542 . One surface 5421 of the second battery 542 has a first area 542a facing the first flexible printed circuit board 610 and a second area facing the fourth portion 582 of the antenna structure 580 . (542b). The one surface 5421 may be, for example, substantially flat. A fourth portion 582 of the antenna structure 580 may be positioned in a space between the first flexible printed circuit board 610 and the second region 542b. According to various embodiments, the fourth portion 582 of the antenna structure 580 including the second coil ② may not protrude with respect to the first layer 1010 in the -z axis direction.

It may be greater than the second distance spaced apart from one surface 5421 in the -z axis direction. According to some embodiments, the first distance and the second distance may be substantially equal, or the first distance may be less than the second distance.

Although not shown, for example, when the antenna structure 580 is implemented including both the first coil (①) (see FIG. 8) and the second coil (②), the antenna structure 580 is the embodiment of FIG. 10 . It may be thicker than the example, and thus it may be difficult to secure a space for disposing the second battery 542 . In a situation in which a slimmer form factor of an electronic device is sought while increasing the size of the battery to increase the battery capacity, the embodiment of FIG. 9 or 10 secures the space occupied by the second battery 542 (eg, space in the z-axis direction). ) can be convenient. In addition, when the antenna structure 580 is implemented to include both the first coil (①) (see FIG. 8) and the second coil (②), the first coil (①) and electromagnetic separation (isolation) for reasons of 2 The diameter (D) of the coil (②) may be limited, but the embodiment of FIG. 9 or 10 may be easier to further expand the diameter (D). When the diameter D satisfies the WPC standard and is maximally formed, when the electronic device 20 is mounted on the wireless charging device for wireless charging, charging efficiency may be increased due to the expansion of the wireless charging recognition area.

According to various embodiments, the second layer 1020 and the third layer 1030 may be arranged to be electromagnetically coupled. For example, the distance between the second layer 1020 and the third layer 1030 is such that the second layer 1020 and the third layer 1030 are not electromagnetically isolated, so that the first coil ① ) (refer to FIG. 8) and/or may be formed based on a wavelength of a radio wave radiated from the second coil (②). The electromagnetic coupling between the second layer 1020 and the third layer 1030 allows the electromagnetic wave energy radiated from the first coil (①) to be concentrated in a specific direction in space, thereby improving the antenna radiation performance of the first coil (①). can be improved The electromagnetic coupling between the second layer 1020 and the third layer 1030 allows the electromagnetic wave energy radiated from the second coil (②) to be concentrated in a specific direction in space, thereby improving the antenna radiation performance of the second coil (②). can be improved For example, electromagnetic wave energy radiated from the first coil (①) or the second coil (②) is substantially generated by electromagnetic coupling between the second layer 1020 and the third layer 1030 in FIG. 3 . The face 206 may be focused in the direction it is facing or have a directivity or directivity that may transmit or receive waves. By the electromagnetic coupling between the second layer 1020 and the third layer 1030, a set boundary condition for the electromagnetic field from the first coil (①) or the second coil (②) is formed to form a specific The electromagnetic energy can be guided in the direction. For example, electromagnetic coupling between the second layer 1020 and the third layer 1030 may diffuse radio waves radiated from the first coil (①) or the second coil (②). For example, due to electromagnetic coupling between the second layer 1020 and the third layer 1030, it passes between the second layer 1020 and the third layer 1030 and passes through the sixth side ( 206) may be formed to be concentrated in the direction in which electromagnetic energy is directed. The electromagnetic coupling between the second layer 1020 and the third layer 1030 reduces the decrease in magnetic flux by the surrounding conductive medium contained in the second housing part 220 (see FIG. 3 ), so that the first The radiation performance of the coil (①) or the second coil (②) can be secured. When the decrease in magnetic flux is reduced, electromagnetic wave energy is increased due to an increase in an inductance value, and thus antenna radiation performance may be improved. The electromagnetic coupling between the second layer 1020 and the third layer 1030 occurs in a peripheral element (eg, a metal member, or an integrated circuit) included in the second housing portion 220 (see FIG. 3 ). By reducing the loss of electromagnetic wave energy due to the eddy current, it is possible to secure the antenna radiation performance for the first coil (①) or the second coil (②).

According to an embodiment, the third distance the second layer 1020 is spaced apart from the one surface 5421 of the second battery 542 in the -z axis direction is that the third layer 1030 is the second battery 542 of the second battery 542 . It may be different from the fourth distance spaced apart from the one surface 5421 in the -z axis direction. If the third distance and the fourth distance are different, the first coil due to electromagnetic coupling between the second layer 1020 and the third layer 1030 between the second layer 1020 and the third layer 1030 Radiation performance for (①) or the second coil (②) can be secured. For example, when the third distance and the fourth distance are the same, loss (eg, leakage) of electromagnetic energy may occur through electromagnetic coupling between the second layer 1020 and the third layer 1030 . For example, the second layer 1020 and the third layer 1030 disposed on the same plane with an electromagnetic coupling distance may be difficult to guide electromagnetic energy in a specific direction.

For example, the electromagnetic wave energy may be guided in a specific direction by forming a set boundary condition for the electromagnetic field from the antenna structure 580 by the overlapping structure. For example, the overlapping structure may spread the radio wave radiated from the antenna structure 580 . For example, due to electromagnetic coupling between the first magnetic sheet 1110 and the second magnetic sheet 1120, the antenna structure ( Electromagnetic energy concentrated in a direction toward which one surface 580a of the 580 is directed may be formed. The overlapping structure reduces the decrease in magnetic flux by the peripheral conductive medium included in the second housing part 220 (refer to FIG. 3 ), thereby securing the radiation performance of the antenna structure 580 . When the decrease in magnetic flux is reduced, electromagnetic wave energy may be increased due to an increase in inductance value, and thus radiation performance may be improved.
