As a result, the shield 610 penetrates electromagnetic waves from each other between at least one of the MST antenna 297-1, the NFC antenna 297-3, or the wireless charging antenna 297-5 and the battery 189. Can be blocked.

The protection unit 620 may protect the antenna module 197. The protection unit 620 may include the MST antenna 297-1 between the MST antenna 297-1, the NFC antenna 297-3, or the wireless charging antenna 297-5 and the rear plate 430. At least one of the NFC antenna 297-3 and the wireless charging antenna 297-5 may be protected. The protection part 620 may be in close contact with the back plate 430. The protection unit 620 is opposite to the shield 610 with at least one of the MST antenna 297-1, the NFC antenna 297-3, or the wireless charging antenna 297-5 interposed therebetween. 297-1, the NFC antenna 297-3, or the wireless charging antenna 297-5 may be covered. For example, the protection unit 620 may include flexible electronics (FPCB).

At least one of the radiator of the MST antenna 297-1, the radiator of the NFC antenna 297-3, or the radiator of the wireless charging antenna 297-5 is disposed between the shield 610 and the protector 620. In, may be formed in a coil shape. For example, the radiating section of the wireless charging antenna 297-5 is disposed outside the radiating section of the MST antenna 297-1, and the NFC antenna 297- is located outside the radiating section of the wireless charging antenna 297-5. Radiating portions 341 and 343 of 3) may be disposed. For example, the pattern portion 341 of the NFC antenna 297-3 may be disposed outside the MST antenna 297-1 and the wireless charging antenna 297-5. At least one of the MST antenna 297-1, the NFC antenna 297-3, or the wireless charging antenna 297-5 may be designed to resonate at a predetermined frequency, respectively. NFC antenna 297-3 may be initially designed to operate at a designated first frequency. NFC antenna 297 may be initially designed to operate at a first frequency when no pressure is applied to NFC antenna 297.

According to an embodiment, in the NFC antenna 297-3, the detector 345 may be disposed adjacent to the radiators 341 and 343. For example, the detector 345 may be directly connected to the radiators 341 and 343. As another example, the sensing unit 345 is spaced apart from the radiating parts 341 and 343, and electromagnetically coupled to the radiating parts 341 and 343 in response to the operations of the radiating parts 341 and 343. It may be electromagnetically connected to the dead ends 341 and 343. When pressure is applied to the NFC antenna 297-3, the capacitance of the detector 345 may change. Through this, the frequency of the NFC antenna 297-3 may be changed from the first frequency to the second frequency.

The sensing unit 345 may include an adhesive unit 643 and a variable unit 645. The adhesive part 643 may be attached to the variable part 645 and the shielding part 610. The adhesion part 643 may adhere the variable part 645 to the shielding part 610. The variable part 645 may be in close contact with the battery 189 through the shielding part 610, and may be in close contact with the back plate 430 through the protection part 620. For this reason, when swelling defects occur due to a swelling phenomenon in the battery 189, pressure may be applied to the variable portion 645. The capacitance of the variable part 645 may vary according to a pressure value applied to the variable part 645 between the battery 189 and the rear plate 430. For example, as the pressure value applied to the variable portion 645 increases as shown in Table 1 below, the capacitance of the variable portion 645 may increase. That is, the larger the pressure value applied to the variable part 645, the larger the change in capacitance of the variable part 645.

For example, the variable part 645 may include a membrane material. The variable part 645 may be formed by combining a plurality of conductive balls 646 and nanofibers 647, as shown in FIG. 6C. Through this, the capacitance of the variable part 645 may be determined according to the spacing of the conductive balls 646. The capacitance of the variable portion 645 may vary to be inversely proportional to the spacing of the conductive balls 646. For example, as the pressure applied to the variable portion 645 is increased, the distance between the conductive balls 646 may be reduced, thereby increasing the capacitance of the variable portion 645. On the other hand, as the pressure applied to the variable portion 645 is reduced, the distance between the conductive balls 646 is increased, the capacitance of the variable portion 645 can be reduced.

For example, when a swelling defect occurs due to a swelling phenomenon in the battery 189, pressure is applied to the NFC antenna 297-3, and thus the frequency of the NFC antenna 297-3 may change. When a swelling failure occurs due to a swelling phenomenon in the battery 189, the pressure value applied to the NFC antenna 297-3 may be continuously maintained. For this reason, when the pressure value applied to the NFC antenna 297-3 is continuously maintained, the frequency change of the NFC antenna 297-3 may be continuously maintained.

For example, the processor 120 may calculate the frequency of the NFC antenna 297-3 from the signal transmission time in the NFC antenna 297-3 as shown in Equation 2 above. As an example, if the pressure applied to the NFC antenna 297-3, for example, the variable portion 645 is about 0 kgf, the values of the parameters in the NFC antenna 297-3 may be applied to the initial design as shown in Table 2 above. It can remain the same as the values of the parameters according. Accordingly, the second frequency may be the same as the first frequency. As another example, if the pressure applied to the NFC antenna 297-3, for example, the variable portion 645 is about 20 kgf, the values of the parameters in the NFC antenna 297-3 may be applied to the initial design as shown in Table 2 above.
