[0167] In one embodiment, the notification provided to the user of the electronic device (200) may be provided in the form of a vibration of the electronic device (200) or a sound generated by the electronic device (200).

[0168] Referring to FIG. 9b, the first housing (210) and the second housing (220) can be spread out so that one side of the first housing (210) and one side of the second housing (220) are separated from each other.

[0169] When the first housing (210) and the second housing (220) are unfolded while the input device (300) is attached to the other side of the first housing (210), the input device (300) is positioned between the electronic device (200) and the external structure (ST) (e.g., the floor surface on which the electronic device (200) is placed), the input device (300) may come into contact with the external structure (ST), causing damage to the electronic device (200) and the input device (300).

[0170] In one embodiment, the electronic device (200) may provide a notification when the first housing (210) and the second housing (220) are opened beyond a predetermined angle while the input device (300) is attached to the other side of the first housing (210) (e.g., the state illustrated in FIG. 9B) in order to prevent damage to the electronic device (200) and the input device (300) due to the opening of the first housing (210) and the second housing (220).

[0171] In one embodiment, the notification provided to the user of the electronic device (200) may be provided in a form displayed on a display (230, 240, see FIG. 3).

[0172] In one embodiment, the notification provided to the user of the electronic device (200) may be provided in the form of a vibration of the electronic device (200) or a sound generated by the electronic device (200).

[0173] In one embodiment, the electronic device (200) may provide a notification to a user under the control of a processor (e.g., processor (120) of FIG. 1).

[0174] FIG. 10A and FIG. 10B are drawings showing a side surface (210A) of a first housing (210) and an input device (300) disposed on the side surface (210A) of the first housing (210) according to one embodiment of the present disclosure.

[0175] FIG. 10A is a drawing showing a side surface (210A) of a first housing (210) according to one embodiment. FIG. 10B is a drawing showing an input device (300) attached to the side surface (210A) of the first housing (210) according to one embodiment.

[0176] FIG. 11 is a flowchart of a method (1100) for changing antenna impedance by attaching an input device (300) according to one embodiment of the present disclosure.

[0177] Referring to FIG. 10A, the side surface (210A) of the first housing (210) may include at least one antenna (295). For example, the side surface (210A) of the first housing (210) may be formed as a frame including an antenna (295) for wireless communication.

[0178] Referring to FIG. 10A, each antenna (295) may be positioned with an antenna segment (290) therebetween. The antenna segment (290) may serve to adjust the length of the antenna (295) formed on the side (210A) of the first housing (210).

[0179] Referring to FIG. 10b, an input device (300) may be attached to a side surface (210A) of the first housing (210). When the input device (300) is attached to the side surface (210A) of the first housing (210), the input device (300) may come into contact with the antenna (295) and the antenna segment (290), which may deteriorate the performance of the antenna (295).

[0180] In one embodiment, the electronic device (200) can change the impedance of the antenna (295) to prevent performance degradation of the antenna (295) due to an input device (300) attached to a side (210A) of the first housing (210). For example, referring to FIG. 11, the electronic device (200) can change the impedance of the antenna (295) by performing an operation according to an antenna impedance changing method (1100).

[0181] In one embodiment, the antenna impedance changing method (1100) may be performed according to, for example, the flowchart illustrated in FIG. 11. The flowchart illustrated in FIG. 11 is merely a flowchart according to one embodiment of the antenna impedance changing method (1100), and therefore, the order of each operation may be changed or performed simultaneously.

[0182] In one embodiment, each operation of the antenna impedance change method (1100) may be performed in a processor of the electronic device (200) (e.g., processor (120) of FIG. 1), or may be performed using at least one of a wireless communication module (e.g., wireless communication module (192) of FIG. 1) and / or a sensor module (e.g., sensor module (176) of FIG. 1).

[0183] Referring to FIG. 11, the method for changing the antenna impedance (1100) may include an operation (1110) of connecting communication through an antenna (295), an operation (1120) of checking whether an external device (e.g., an input device (300)) is attached, an operation (1130) of checking a location where the external device is attached, an operation (1140) of checking whether an external device is attached to a side (210A) of a housing (210), an operation (1150) of changing the impedance of the antenna (295), and / or an operation (1160) of maintaining a basic state of an electronic device (200).

[0184] In one embodiment, in a communication connection (1110) operation, the electronic device (200) may be connected to a wireless communication via an antenna (295).

[0185] In one embodiment, wireless communication via the antenna (295) may be influenced by an input device (300) positioned corresponding to the antenna (295).

[0186] In one embodiment, the external device may mean an input device (300) attached to the electronic device (200).

[0187] According to one embodiment, the electronic device (200) can, under the control of the processor (120), check whether an input device (300) is attached to the electronic device (200) in an external device attachment check operation (1120).

[0188] According to one embodiment, the electronic device (200) can, under the control of the processor (120), determine the location where the input device (300) is attached in the external device attachment location confirmation operation (1130). The electronic device (200) can determine where the input device (300) is attached in the electronic device (200). For example, the electronic device (200) can determine where the input device (300) is attached in the first area (232A), the second area (242A), or the side surface (210A) of the first housing (210).

[0189] An electronic device (200) according to one embodiment can, under the control of a processor (120), check whether an input device (300) is attached to a side (210A) of a first housing (210) in a housing side attachment check operation (1140).

[0190] In one embodiment, the electronic device (200) can check whether the input device (300) is attached and the attachment location through a hall sensor or a touch sensor in the operation of checking whether the external device is attached (1120), the operation of checking the external device attachment location (1130), and the operation of checking the housing side attachment (1140), or can check whether the input device (300) is attached and the attachment location by using the impedance change of the coil (250, 450).

[0191] According to one embodiment, the electronic device (200) can change the impedance of the antenna (295) in an antenna impedance change operation (1150) under the control of the processor (120). The electronic device (200) can change the impedance of the antenna (295) only when it is confirmed that the input device (300) is attached to the side (210A) of the first housing (210) in the housing side attachment confirmation operation (1140).

[0192] When an input device (300) is attached to the side (210A) of the first housing (210), the performance of the antenna (295) may be degraded due to the influence of the input device (300). According to one embodiment, the electronic device (200) may prevent or reduce the performance deterioration of the antenna (295) due to the input device (300) by changing the impedance of the antenna (295) in the antenna impedance changing operation (1150).

[0193] In one embodiment, the electronic device (200) may use a device internal to the antenna (295) or a device separately connected to the antenna (295) to change the impedance of the antenna (295) in the antenna impedance change operation (1150). For example, the electronic device (200) may change the impedance of the antenna (295) through a switch of the antenna (295) itself. Alternatively, the electronic device (200) may change the impedance of the antenna (295) through a tuner (not shown) electrically connected to the antenna (295).

[0194] In one embodiment, the electronic device (200) may, in the antenna impedance changing operation (1150), change the antenna (295) being used for the communication connection to another antenna (295) that is not affected by the input device (300). For example, the electronic device (200) may, in the antenna impedance changing operation (1150), enable the communication connection using an antenna (295) that is not in contact with the input device (300).

[0195] According to one embodiment, the electronic device (200) may, under the control of the processor (120), cause the antenna (295) of the electronic device (200) to maintain the default state in a default state maintenance operation (1160). The default state of the antenna (295) may mean a state in which the impedance of the antenna (295) is maintained without changing. If the electronic device (200) determines that the input device (300) is not attached to the electronic device (200) in the input device attachment confirmation operation (1120), the electronic device (200) may cause the impedance of the antenna (295) of the electronic device (200) to be maintained in the default state without changing it through the default state maintenance operation (1160). If the electronic device (200) determines that the input device (300) is not attached to the side (210A) of the housing (210) in the housing side attachment confirmation operation (1140), the electronic device (200) can maintain the basic state without changing the impedance of the antenna (295) through the basic state maintenance operation (1160).

[0261] An embodiment of the present disclosure may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0262] According to one embodiment, the method according to various embodiments of the present disclosure may be provided as included in a computer program product.
