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).

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).

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 the input device (300) attached to the 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 the antenna impedance changing method (1100).

In one embodiment, the antenna impedance changing method (1100) may be performed according to, for example, the flow chart illustrated in FIG. 11. The flow chart illustrated in FIG. 11 is merely a flow chart according to one embodiment of the antenna impedance changing method (1100), so the order of each operation may be changed or performed simultaneously.

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

Referring to FIG. 11, the method for changing 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 an 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).

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

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

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

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).

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

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

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 external device attachment confirmation operation (1120), the external device attachment location confirmation operation (1130), and the housing side attachment confirmation operation (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).

An electronic device (200) according to one embodiment can change the impedance of an antenna (295) in an antenna impedance changing operation (1150) under the control of a 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 a housing side attachment confirmation operation (1140).

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).

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).

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).

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 an 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).
