[0213] 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 through the first electrical path (EP11) and the second power supply through the second electrical path (EP12). Voltages (also called feed voltages) of opposite polarities (+ voltage (e.g., positive voltage) and - voltage (e.g., negative voltage)) can be provided to the seventh metal portion (E7) through the first feed and the second feed.

[0214] According to various embodiments, when power is supplied from the second wireless communication circuit (620), a first current path (also referred to as a first signal path or a first loop) may be formed through which a current (also referred to as a radiated current) flows between the first electrical path (EP11) and the second electrical path (EP12) through the seventh metal portion (E7) due to a potential difference between the third contact portion (P3) and the fourth contact portion (P4) of the seventh metal portion (E7).

[0215] 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) may be interpreted as a first NFC antenna (or, also referred to as a first NFC antenna structure) configured to radiate a first electromagnetic field of an NFC band through the seventh metal portion (E7) when powered from the second wireless communication circuit (620). For example, the first NFC antenna may include at least one matching circuit for frequency tuning, inductance value tuning, and / or impedance matching, or at least one filter, or a combination thereof.

[0216] According to various embodiments, in the unfolded state of the foldable electronic device (2), when power is supplied from 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 reduce the reduction in the magnetic flux of the first electromagnetic field radiated through the seventh metal portion (E7) by the second ground region (G2), thereby reducing the deterioration of the antenna radiation performance for the NFC band. When the reduction in the magnetic flux by the second non-ground region (NG2) in the unfolded state of the foldable electronic device (2) is reduced, the energy of the first electromagnetic field increases due to an increase in the inductance value, so that the antenna radiation performance for the NFC band can be secured and / or improved.

[0217] According to various embodiments, in the folded state of the foldable electronic device (2), when power is supplied from 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 first non-ground region (NG1) and the second non-ground region (NG2) that are aligned with each other. Since the electromagnetic force of the first electromagnetic field radiated through the seventh metal portion (E7) passes through the first non-ground region (NG1) and the second non-ground region (NG2) that are aligned with each other, the reduction in magnetic flux by the first non-ground region (NG1) and the second non-ground region (NG2) can be reduced. When the reduction in magnetic flux by the first non-ground region (NG1) and the second non-ground region (NG2) is reduced, the energy of the first electromagnetic field increases due to an increase in the inductance value, so that the antenna radiation performance for the NFC band can be secured and / or improved.

[0218] According to various embodiments, in a folded state of the foldable electronic device (2), the first metal portion (E1) and the seventh metal portion (E7) may be aligned so as to reduce or prevent a deterioration in antenna radiation performance of a Non-NFC antenna configured to radiate an electromagnetic field in a Non-NFC band through the first metal portion (E1) and / or in antenna radiation performance of a first NFC antenna configured to radiate a first electromagnetic field in an NFC band through the seventh metal portion (E7), so as to reduce or prevent a deterioration in antenna radiation performance of the Non-NFC antenna configured to radiate an electromagnetic field in an NFC band through the seventh metal portion (E7).

The distribution of the current along the second current path may form a second electromagnetic field (or a second magnetic field distribution) through the coil-shaped conductive pattern (630). The second wireless communication circuit (620) may be configured to transmit and / or receive a signal in the NFC band through the second electromagnetic field radiated (or formed or generated) through the coil-shaped conductive pattern (630).

[0229] According to various embodiments, the combination of the coil-shaped conductive pattern (e.g., the second NFC antenna radiator) (630), the third electrical path (EP13), and the fourth electrical path (EP14) may be interpreted as a second NFC antenna (or, 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) when powered from the second wireless communication circuit (620). For example, the second NFC antenna may include at least one matching circuit for frequency tuning, inductance value tuning, and / or impedance matching, or at least one filter, or a combination thereof.

[0230] According to various embodiments, when power is supplied from the second wireless communication circuit (620), the first electromagnetic field radiated from the seventh metal portion (E7) may be less likely to be included in the grip position of the user's hand with respect to 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) may reduce restrictions on the grip position of the user's hand with respect to the foldable electronic device (2) in the unfolded or folded state and may reduce the possibility of the radiation performance being degraded by the user's hand (e.g., a dielectric).

The first matching circuit (M11), the second matching circuit (M12), and / or the third matching circuit (M13) may shift the resonant frequency of the seventh metal portion (E7) to a specified frequency, or shift the resonant frequency by a specified amount. Due to the frequency adjustment by the first matching circuit (M11), the second matching circuit (M12), and / or the third matching circuit (M13), the first electromagnetic field radiated from the seventh metal portion (E7) when powered from the second wireless communication circuit (620) may have a resonant frequency of about 13.56 MHz for NFC.

[0234] According to various embodiments, the first matching circuit (M11), the second matching circuit (M12), and / or the third matching circuit (M13) may be configured to adjust an inductance value.
