[0216] According to various embodiments, the second wireless communication circuit 620 can provide a first power supply and a second power supply to the seventh metal portion E7. The second wireless communication circuit 620 can provide the first power supply via a first electrical path EP11 and the second power supply via a second electrical path EP12. Voltages of opposite polarities (also referred to as feed voltages) (+ voltage (e.g., positive voltage) and - voltage (e.g., negative voltage)) can be provided to the seventh metal portion E7 via the first power supply and the second power supply. For example, a + voltage (also referred to as the first feed voltage or first feed signal) can be provided to the third contact portion P3 of the seventh metal portion E7 via the first power supply and the first electrical path EP11, and a - voltage (also referred to as the second feed voltage or second feed signal) can be provided to the fourth contact portion P4 of the seventh metal portion E7 via the second power supply and the second electrical path EP12.

[0217] According to various embodiments, during the power-on period of the second wireless communication circuit 620, a first current path (also referred to as a first signal path or a first loop) can be formed due to the potential difference between the third contact portion P3 and the fourth contact portion P4 of the seventh metal portion E7. Current (also referred to as radiated current) flows through the seventh metal portion E7 between the first electrical path EP11 and the second electrical path EP12 via the first current path. The current distribution along the first current path can form a first electromagnetic field (or a first magnetic field distribution) through the seventh metal portion E7. The second wireless communication circuit 620 can be configured to transmit and / or receive NFC band signals via the first electromagnetic field radiated (or formed or generated) through the seventh metal portion E7.

[0218] According to various embodiments, the combination of the seventh metal portion (e.g., the first NFC antenna radiator) E7, the first electrical path EP11, and the second electrical path EP12 can be interpreted as a first NFC antenna (also referred to as a first NFC antenna structure), which is configured to radiate a first electromagnetic field in the NFC frequency band through the seventh metal portion E7 during the feeding of the second wireless communication circuit 620. For example, the first NFC antenna may include at least one matching circuit, or at least one filter, or a combination thereof, for frequency tuning, inductance tuning, and / or impedance matching.

[0219] According to various embodiments, in the unfolded state of the foldable electronic device 2 and during the power-on period of the second wireless communication circuit 620, the electromagnetic force of the first electromagnetic field radiated through the seventh metal portion E7 can pass through the second non-ground region NG2 between the seventh metal portion E7 and the second ground region G2. In the unfolded state of the foldable electronic device 2, the second non-ground region NG2 can suppress the reduction of the magnetic flux of the first electromagnetic field radiated through the seventh metal portion E7 by the second ground region G2, thereby suppressing the degradation of the antenna radiation performance of the NFC band. When the reduction of magnetic flux caused by the second non-ground region NG2 is suppressed in the folded state of the foldable electronic device 2, the energy of the first electromagnetic field increases due to the increase in inductance, thereby ensuring and / or improving the antenna radiation performance of the NFC band.

[0220] According to various embodiments, in the folded state of the foldable electronic device 2 and during the power-on period of the second wireless communication circuit 620, the electromagnetic force of the first electromagnetic field radiated by the seventh metal portion E7 can pass through the first non-ground region NG1 and the second non-ground region NG2 aligned with each other. Since the electromagnetic force of the first electromagnetic field radiated by the seventh metal portion E7 passes through the first non-ground region NG1 and the second non-ground region NG2 aligned with each other, the reduction in magnetic flux caused by the first non-ground region NG1 and the second non-ground region NG2 can be suppressed. When the reduction in magnetic flux caused by the first non-ground region NG1 and the second non-ground region NG2 is suppressed, the energy of the first electromagnetic field can increase due to the increase in inductance, thereby ensuring and / or improving the antenna radiation performance of the NFC band.

[0221] According to various embodiments, since the first metal portion E1 and the seventh metal portion E7 are close to and aligned with each other in the folded state of the foldable electronic device 2, in order to suppress or prevent the degradation of the antenna radiation performance of the non-NFC antenna configured to radiate electromagnetic fields in the non-NFC band through the first metal portion E1 and / or the antenna radiation performance of the first NFC antenna configured to radiate the first electromagnetic field in the NFC band through the seventh metal portion E7, the first contact portion P1 of the first metal portion E1 may be misaligned with the fourth contact portion P4 of the seventh metal portion E7. In various embodiments, when the foldable electronic device 2 is in the folded state from the first cover 212 (see... Figure 3 ) or second cover 222 (see Figure 3 When viewed from above (or in a direction orthogonal to the first cover 212 or the second cover 222), the first contact portion P1 and the fourth contact portion P4 may not overlap each other. In various embodiments, when the foldable electronic device 2 is in its folded state, when viewed from the first cover 212 (see above), the first contact portion P1 and the fourth contact portion P4 may not overlap each other.

[0222] According to various embodiments, during the power-on period of the first wireless communication circuit 610, the density of the radiated current in the first metal portion E1 can be relatively high in the first contact portion P1 and the second contact portion P2. During the power-on period of the second wireless communication circuit 620, the density of the radiated current in the seventh metal portion E7 can be relatively high in the third contact portion P3 and the fourth contact portion P4. In order to reduce the electromagnetic influence between at least a portion of the first metal portion E1 with a relatively high radiated current density during the power-on period of the first wireless communication circuit 610 and at least a portion of the seventh metal portion E7 with a relatively high radiated current density during the power-on period of the second wireless communication circuit 620, in the folded state of the foldable electronic device 2, the first contact portion P1 and / or the second contact portion P2 of the first metal portion E1 can be misaligned with the third contact portion P3 and / or the fourth contact portion P4 of the seventh metal portion E7.

The second wireless communication circuit 620 can be configured to transmit and / or receive NFC band signals via the second electromagnetic field radiated (or formed or generated) through the coil-shaped conductive pattern 630.

[0232] According to various embodiments, the combination of the coil-shaped conductive pattern (e.g., a second NFC antenna radiator) 630, the third electrical path EP13, and the fourth electrical path EP14 can be interpreted as a second NFC antenna (also referred to as a second NFC antenna structure) configured to radiate a second electromagnetic field in the NFC band through the coil-shaped conductive pattern 630 during the feeding of the second wireless communication circuit 620. For example, the second NFC antenna may include at least one matching circuit, or at least one filter, or a combination thereof, for frequency tuning, inductance tuning, and / or impedance matching.

[0233] According to various embodiments, during the power-on period of the second wireless communication circuit 620, the first electromagnetic field radiated from the seventh metal portion E7 is less likely to be included in the user's hand grip position of the foldable electronic device 2 in the unfolded or folded state compared to the second electromagnetic field radiated from the coil-shaped conductive pattern 630. The first electromagnetic field radiated from the seventh metal portion E7 can reduce the restriction on the user's hand grip position of the foldable electronic device 2 in the unfolded or folded state and can reduce the possibility of radiation performance being degraded by the user's hand (e.g., dielectric). The foldable electronic device 2 according to this disclosure provides not only a second electromagnetic field in the NFC band through the coil-shaped conductive pattern 630, but also a first electromagnetic field in the NFC band through the seventh metal portion E7, thereby allowing the NFC recognition area for external electronic devices to be extended by a relatively further extended electromagnetic field distribution.

[0234] According to various embodiments, the foldable electronic device 2 may include a first matching circuit M11 housed in a first housing 21. For example, the first matching circuit M11 may be disposed on a printed circuit board (not shown separately) housed in the first housing 21.

The first matching circuit M11, the second matching circuit M12, and / or the third matching circuit M13 can shift the resonant frequency of the seventh metal portion E7 to a predetermined frequency, or shift the resonant frequency by a predetermined amount. Due to the frequency tuning of the first matching circuit M11, the second matching circuit M12, and / or the third matching circuit M13, during the power-on period of the second wireless communication circuit 620, the first electromagnetic field radiated from the seventh metal portion E7 can have a resonant frequency of approximately 13.56 MHz for NFC.

[0237] According to various embodiments, the first matching circuit M11, the second matching circuit M12, and / or the third matching circuit M13 can be configured to tune the inductance value. For example, due to the tuning of the inductance values ​​of the first matching circuit M11, the second matching circuit M12, and / or the third matching circuit M13, during the power-on period of the second wireless communication circuit 620, for approximately 13.56 MHz for NFC, the first electromagnetic field radiated from the seventh metal portion E7 can have an inductance value of approximately 8 to approximately 10 microhenries.

[0328] According to various embodiments, the fourth matching circuit M64 can reduce or prevent electromagnetic interference (e.g., EMI) between a first NFC antenna configured to radiate a first electromagnetic field in the NFC band via the seventh metal portion E7 and a non-NFC antenna configured to radiate an electromagnetic field in a non-NFC band via the first metal portion E1. The fourth matching circuit M64 can also reduce or prevent resonant frequency shifts and / or impedance mismatches in the non-NFC antennas caused by the alignment of the first metal portion E1 and the seventh metal portion E7 with each other in the folded state of the foldable electronics 2.

[0329] According to various embodiments, the fourth matching circuit M64 can be configured as a switching circuit including at least one switch, tuner, or a combination thereof. For example, the fourth matching circuit M64 can be controlled depending on whether the foldable electronic device 2 is in an unfolded or folded state. In various embodiments, the processor included in the foldable electronic device 2 (e.g., Figure 1 Under the control of the processor 120 in the foldable electronic device 2, the fourth matching circuit M64 can tune the value of the time constant.

[0331] According to various embodiments, the fifth contact portion P5 may be located between the contact portion P3 and the twelfth non-metallic portion F12. The location of the fifth contact portion P5 is not limited to the example shown.

[0332] Figure 12 The diagram shows a heat map of the magnetic field distribution of the NFC band during power feeding in the folded state of the foldable electronic device 2, a heat map of the magnetic field distribution of the NFC band during power feeding when the foldable electronic device 1200 according to the comparative example is in the folded state, and a table of NFC performance according to various embodiments.

[0333] refer to Figure 12 According to various embodiments of this disclosure, the foldable electronic device 2 can radiate (or form) a first electromagnetic field EF11 in the NFC band via the seventh metal portion E7 (see...). Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 or Figure 11 ), and radiates (or forms) a second electromagnetic field EF12 in the NFC band through the coil-shaped conductive pattern 630 (see Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 or Figure 11 The foldable electronic device 2 in its folded state may include an upper region 1211, a lower region 1213, and an intermediate region between the upper region 1211 and the lower region 1213. The upper region 1211 may be a first edge B1 of the foldable electronic device 2 that is aligned with each other in the folded state of the foldable electronic device 2 (see [link to relevant documentation]). Figure 3 ) and the fifth edge B5 (see Figure 3 The lower region 1213 may be a third edge B3 of the foldable electronic device 2 that is aligned with each other in the folded state of the foldable electronic device 2 (see [reference]). Figure 3 ) and the seventh edge B7 (see Figure 3The other side region of the foldable electronic device 2.

During power feeding in the folded state, a second electromagnetic field radiated from the coil-shaped conductive pattern 630 can be radiated through the middle region of the foldable electronic device 2 in the direction facing the first rear surface region 1212. Compared to the second electromagnetic field radiated from the coil-shaped conductive pattern 630, the first electromagnetic field radiated from the seventh metal portion E7 is less likely to be included in the user's hand grip position of the foldable electronic device 2 in the unfolded or folded state. The first electromagnetic field radiated from the seventh metal portion E7 can reduce the restriction on the user's hand grip position of the foldable electronic device 2 in the unfolded or folded state, and can reduce the possibility of radiation performance being degraded by the user's hand (e.g., dielectric). The foldable electronic device 2 according to this disclosure provides not only a second electromagnetic field for the NFC band through the coil-shaped conductive pattern 630, but also a first electromagnetic field for the NFC band through the seventh metal portion E7, thereby allowing the NFC recognition area for external electronic devices to be extended through a relatively further extended electromagnetic field distribution.

[0338] "1234" can indicate that the foldable electronic device 2 in a folded state according to various embodiments of the present disclosure is configured in a fourth orientation of approximately 180 degrees. In this fourth orientation, the second rear region 1212 may be oriented toward the direction 1221 from which an electromagnetic field is radiated from the external electronic device 1220. For example, in the fourth orientation of the foldable electronic device 2 according to various embodiments of the present disclosure, NFC identification for the external electronic device 1220 may be impossible. For example, in the fourth orientation of the foldable electronic device 1200 according to the comparative example, NFC identification for the external electronic device 1220 may be impossible.
