[0063] For example, at least one of the first electrical path (P1), the second electrical path (P2), the third electrical path (P3), and / or the fourth electrical path (P4) may include a protection circuit not shown. For example, the protection circuit may include, but is not limited to, a Zener diode connected to at least one of the first electrical path (P1), the second electrical path (P2), the third electrical path (P3), and / or the fourth electrical path (P4).

For example, but not limited to, the fourth circuit (84) may include a capacitor.

[0066] In one embodiment, the common path (C2) may connect the second electrode (42) to a third electrical path (P3) and a fourth electrical path (P4). For example, a first end of the common path (C2) may be connected to the second electrode (42), and a second end of the common path (C2) may be connected to a third electrical path (P3) and a fourth electrical path (P4). The fourth electrical path (P4) may branch off at a point (N2) of the third electrical path (P3) located between the second electrode (42) and the third circuit (83). The third circuit (83) and the fourth circuit (84) may be connected in parallel to the second electrode (42). For non-limiting example, the common path (C2) may be understood to be included in the third electrical path (P3) and / or the fourth electrical path (P4).

[0067] In one embodiment, the second circuit (82) and the third circuit (83) may be at least partially integrated. Accordingly, the second electrical path (P2) and the third electrical path (P3) may also be at least partially integrated, but this is not limited thereto.

Alternatively, at least one of the first circuit (81), the second circuit (82), the third circuit (83), the fourth circuit (84), the sensor circuit (90), and / or the switch circuit (95) may be disposed on another substrate distinct from the substrate (52) (e.g., the printed circuit board (380) of FIG. 3). For example, referring to FIGS. 5, 6, and 12 together, the first circuit (81), the third circuit (83), and the sensor circuit (90) may be disposed on the substrate (52), and the processor may be disposed on the printed circuit board (380). In this case, the first electrical path (P1) (or the third electrical path (P3)) connected to the first electrode (41) (or the second electrode (42)) may include a first path extending from the first connection portion (61) (or the second connection portion (62)) to the first circuit (81) (or the third circuit (83)) and a second path extending from the first circuit (81) (or the third circuit (83)) to the sensor circuit (90).

[0070] For example, the first circuit (81) and the third circuit (83) may be disposed on the substrate (52), and the sensor circuit (90) may be disposed on the printed circuit board (380). In this case, the first electrical path (P1) (or the third electrical path (P3)) connected to the first electrode (41) (or the second electrode (42)) may include a first path extending from the first connection portion (61) (or the second connection portion (62)) to the first circuit (81) (or the third circuit (83)), a third path extending from the first circuit (81) (or the third circuit (83)) to the connector (53) of the substrate (52), a fourth path extending from the connector (53) of the substrate (52) to the connector (1220) of the printed circuit board (380), and a fifth path extending from the connector (1220) of the printed circuit board (380) to the sensor circuit (90). For example, the second circuit (82) and the fourth circuit (84) may be disposed on the substrate (52), and the switch circuit (95) may be disposed on the printed circuit board (380). In this case, the second electrical path (P2) (or the fourth electrical path (P4)) may include a first path extending from the first connection portion (61) (or the second connection portion (62)) to the second circuit (82) (or the fourth circuit (84)), a second path extending from the second circuit (82) (or the fourth circuit (84)) to the connector (53) of the substrate (52), a third path extending from the connector (53) of the substrate (52) to the connector (1220) of the printed circuit board (380), and a fourth path extending from the connector (1220) of the printed circuit board (380) to the switch circuit (95).

[0071] However, the configuration providing the first electrical path (P1), the second electrical path (P2), the third electrical path (P3), and the fourth electrical path (P4) is not limited to the above-described example, and may vary depending on the positions where the first circuit (81), the second circuit (82), the third circuit (83), the fourth circuit (84), the sensor circuit (90), and the switch circuit (95) are arranged.

[0072] FIG. 10 is a diagram illustrating an exemplary switch circuit according to one embodiment. Referring to FIG. 10, the switch circuit (95) may include a first pin (or terminal) (1), a second pin (2), a third pin (3), a fourth pin (4), a fifth pin (5), and / or a sixth pin (6).

[0073] In one embodiment, the switch circuit (95) may be electrically connected to the electrode (40) and the ground of the antenna. For example, the first pin (1) of the switch circuit (95) may be connected to the electrode (40). For example, the first pin (1) may be connected to the first electrode (41) via the second electrical path (P2) and / or may be connected to the second electrode (42) via the fourth electrical path (P4). For example, the third pin (3) may be connected to the ground of the antenna via the first matching circuit (M1). For example, the fourth pin (4) may be connected to the ground of the antenna via the second matching circuit (M2). For example, the fifth pin (5) may be connected to the ground of the antenna via the third matching circuit (M3). In one embodiment, the first matching circuit (M1), the second matching circuit (M2), and / or the third matching circuit (M3) may be configured such that the interconnected electrodes (40) and the ground of the antenna have different electrical lengths. For non-limiting examples, the first matching circuit (M1), the second matching circuit (M2), and the third matching circuit (M3) may include lumped elements (e.g., inductors and / or capacitors) having different values. In one embodiment, the first matching circuit (M1), the second matching circuit (M2), and / or the third matching circuit (M3) may be omitted.

[0074] In one embodiment, the second pin (2) may be open, but is not limited thereto. For example, the second pin (2) may be connected to the ground of the antenna. In this case, optionally, the second pin (2) may be connected to the ground of the antenna through a matching circuit. In another example, as illustrated in FIG. 13, the second pin (2) may be connected to a conductive member (490).

[0075] In one embodiment, the sixth pin (6) may input a control signal (99) of the switch circuit (95). The control signal (99) may be provided, for example, by a communication processor (e.g., processor (1420) of FIG. 14) of the electronic device (100) or a wireless communication circuit (e.g., wireless communication module (1492) of FIG. 14). In one embodiment, the first pin (1) of the switch circuit (95) may be connected to at least one of the second to fifth pins (2, 3, 4, 5).

[0076] In one embodiment, the switch circuit (95) may be configured to selectively connect the electrode (40) (e.g., the first electrode (41) and / or the second electrode (42)) to the ground of the antenna. The communication processor or the wireless communication circuit may control the switch circuit (95) to selectively connect the electrode (40) to the ground of the antenna.

[0077] In one embodiment, the switch circuit (95) may be configured to selectively connect the first electrode (41) and / or the second electrode (42) to the ground of the antenna. For example, the first electrode (41) and the second electrode (42) may be connected to the first pin (1). In this case, the first pin (1) may be connected to at least one of the second to fifth pins (2, 3, 4, 5). In another example, the first electrode (41) may be connected to the first pin (1), and the second electrode (42) may be connected to the second pin (2). In this case, the switch circuit (95) may connect the first pin (1) and / or the second pin (2) to at least one of the third to fifth pins (3, 4, 5). However, the configuration of the switch circuit (95) for selectively connecting the first electrode (41) and / or the second electrode (42) to the ground of the antenna is not limited to the above-described example, and various modifications may be possible.

[0078] In one embodiment, the first electrode (41) and / or the second electrode (42) may be connected to the ground of the antenna. The ground of the antenna may be expanded by the first electrode (41) and the second electrode (42), thereby improving the performance of the antenna. In addition, the biometric information may be acquired using the first electrode (41) and the second electrode (42). In addition, the first electrode (41) and / or the second electrode (42) may be connected to the ground of the antenna through at least one of the first matching circuit (M1), the second matching circuit (M2), or the third matching circuit (M3). Through this, wireless communication may be adaptively performed depending on the required antenna performance.

[0079] In another embodiment, the first electrode (41) and / or the second electrode (42) may be used as a radiator of an antenna. In this case, a feed line connected to the first electrode (41) and / or the second electrode (42) may be formed on a substrate (e.g., substrate (52) of FIG. 7), and the wireless communication circuit may transmit and receive RF signals through the feed line.

[0080] FIG. 11 is a graph showing the radiation efficiency of an antenna according to an embodiment. The graph (1101) of FIG. 11 shows the radiation efficiency of an electronic device (100) according to an embodiment, and the graph (1105) shows the radiation efficiency of a device according to a comparative example. In the electronic device (100) according to an embodiment, the first electrode (41) and the second electrode (42) may be electrically connected to the ground of the antenna, while the device of the comparative example may not be. Referring to FIG. 11, the radiation efficiency of the graph (1101) may be higher than that of the graph (1105) in a frequency band of about 700 MHz to 1450 MHz. This may be because the ground area of ​​the antenna of the electronic device (100) according to an embodiment is expanded by the first electrode (41) and the second electrode (42). In order to improve the display area, the area of ​​the inactive area (e.g., the black matrix) of the display (e.g., the display (120) of FIG. 3) may be reduced. In this case, the performance (e.g., the mid band of about 1 GHz to 2.3 GHz) of the antenna using the slit between the inactive area of ​​the display and the frame (e.g., the frame (106) of FIG. 3) may be reduced. To prevent this, the conductive layer (e.g., a shielding sheet) of the display that impedes the radiation of the slit may be partially removed. However, this may reduce the ground area of ​​the antenna, thereby reducing the performance (e.g., the low band of about 1 GHz or less) of the antenna. The ground area may be secured through a separate conductive member (e.g., the conductive member (490)), but this may waste space and cost. In contrast, the electronic device (100) according to one embodiment may improve the antenna performance by expanding the ground of the antenna by utilizing the electrode (40) for obtaining biometric information.

Referring to FIG. 12, in one embodiment, a connector (1220), a switch circuit (95), and a connector (1210) may be arranged on a printed circuit board (380). A connecting member (54, FIG. 5) may be connected to the connector (1220). The connector (1210) may be electrically connected to the ground and switch circuit (95) of the antenna.

[0082] In one embodiment, the conductive member (490) may include a first portion (491) and a second portion (492) extending from the first portion (491). The first portion (491) of the conductive member (490) may be disposed on one surface of the first member (3071). The second portion (492) of the conductive member (490) may be positioned on the other surface of the first member (3071) (e.g., the surface facing the printed circuit board (380)) by passing through a hole (367) formed in the first member (3071). For non-limiting examples, the conductive member (490) may include a conductive sheet, a conductive film, or a conductive pattern provided on a flexible printed circuit board.

[0083] In one embodiment, the second portion (492) of the conductive member (490) can be electrically connected by contacting the connector (1210). The conductive member (490) can be electrically connected to the ground and switch circuit (95) of the antenna via the connector (1210).

[0084] Fig. 13 is a diagram illustrating an exemplary switch circuit according to an embodiment. Referring to Fig. 13, a second pin (2) of a switch circuit (95) may be electrically connected to a conductive member (490). The second pin (2) may be electrically connected to the ground of the antenna through the conductive member (490). Through the switch circuit (95), the first electrode (41) and / or the second electrode (42) may be electrically connected to the ground of the antenna through the conductive member (490). Through this, the ground area of ​​the antenna may be further increased.

[0106] FIG. 14 is a block diagram of an electronic device (1401) within a network environment (1400) according to various embodiments. Referring to FIG. 14, in the network environment (1400), the electronic device (1401) may communicate with the electronic device (1402) via a first network (1498) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (1404) or the server (1408) via a second network (1499) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1401) may communicate with the electronic device (1404) via the server (1408). According to one embodiment, the electronic device (1401) may include a processor (1420), a memory (1430), an input module (1450), an audio output module (1455), a display module (1460), an audio module (1470), a sensor module (1476), an interface (1477), a connection terminal (1478), a haptic module (1479), a camera module (1480), a power management module (1488), a battery (1489), a communication module (1490), a subscriber identification module (1496), or an antenna module (1497).

In one embodiment, the auxiliary processor (1423) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1480) or a communication module (1490)). In one embodiment, the auxiliary processor (1423) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1401) where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1408)).
