In some embodiments, at least one of the above components (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments, some of the components described above (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single integrated component (e.g., display module 160).
[0029] Processor 120 may run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 connected to processor 120, and may perform various data processing or calculations.

For example, when electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.
[0030] When the main processor 121 is inactive (e.g., in sleep mode), the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190).

One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0123] The second housing 220 may include a second conductive portion 220-1, which is arranged opposite to or close to at least a portion of the first housing 210. The second conductive portion 220-1 is arranged close to an antenna radiator (e.g., the first conductive portion 210-1) and may therefore affect the resonant characteristics of the antenna radiator. In an electronic device 200 according to some embodiments, a variable element 540 electrically connected to the second conductive portion 220-1 may be arranged within the second housing 220.
[0124] According to one embodiment, the variable element 540 may be arranged adjacent to the sixth sidewall 223 of the second housing 220, which is arranged opposite to or adjacent to the third sidewall 213 of the first housing 210. According to the embodiment, in addition to the portion adjacent to the sixth sidewall 223, the variable element 540 may also be arranged in the portion adjacent to the fifth sidewall 222. Although not shown, the variable element 540 may alternatively be arranged adjacent to the fourth sidewall 221.
[0125] According to one embodiment, the variable element 540 may include a variable capacitor 541 and / or a variable inductor 542. The electronic device 200 can adjust the capacitance and / or inductance of the variable element 540 based on the movement of the second housing 220, thereby adjusting the resonant characteristics of the second conductive portion 220-1. Therefore, according to some embodiments, the electronic device 200 can reduce the impact of the second conductive portion 220-1 of the second housing 220 on the antenna radiator and can increase antenna efficiency.
[0126] Reference Figure 7The antenna driving circuit 530 can be arranged on the first printed circuit board 440 of the first housing 210 and adjacent to the first conductive portion 210-1, which serves as an antenna radiator. The variable element 540 can be arranged on the second printed circuit board 710 adjacent to the second conductive portion 220-1. The first printed circuit board 440 and the second printed circuit board 710 can be electrically connected to each other via a flexible circuit board 720. The flexible circuit board 720 can include lines for transmitting a switching signal output from the antenna driving circuit 530 on the first printed circuit board 440. For example, the switching signal output from the antenna driving circuit 530 can be provided to the variable element 540 on the second printed circuit board 710 via the flexible circuit board 720. According to one embodiment, the capacitance and / or inductance of the variable element 540 can be adjusted in response to the switching signal, and thus the resonant characteristics of the second conductive portion 220-1 can be adjusted. According to other embodiments, the switching signal is not limited to a signal output from the antenna driving circuit and can be output from CP 520 or AP 510.
[0127] According to some embodiments, the flexible circuit board 720 may include at least one of a flexible printed circuit board (FPCB), a flat cable (FRC), or a rigid-flexible printed circuit board (RFCPB). For example, the first printed circuit board 440 may be electrically connected to the second printed circuit board 710 via a flat cable (FRC).
[0128] Figure 8 This is a flowchart illustrating the operation of the electronic device 200 according to an embodiment.
[0129] Figure 8 The operations shown can be performed by a processor (e.g., Figure 1 The processor 120 in the electronic device 200 executes the commands. For example, the memory of the electronic device 200 (e.g., ...) Figure 1 The memory 130 in the memory can store instructions, which, when executed, cause the processor to perform them. Figure 8 The operation is shown below. Refer to the following text for further details. Figure 8 The operation of the electronic device 200 according to an embodiment is described.
[0130] According to another embodiment, it can be provided by a communication processor (e.g., Figure 5 CP 520 in the middle) execution Figure 8 The operation is shown. For example, it includes the communication module (e.g., Figure 1 The communication processor in the communication module 190 (e.g., Figure 5 The CP520 in the middle can receive signals from the AP ( Figure 5 AP510 in the middle) and / or sliding sensor (e.g., Figure 5 The sliding value is sent by the sliding sensor 441 in the middle.
[0131] In operation 810, an electronic device 200 according to one embodiment (e.g., Figure 1 The electronic device 101 in the middle can identify the frequency band currently being used for communication.
[0132] In this disclosure, a frequency band or frequency range can be a frequency band defined in 3GPP. Furthermore, the term "bandwidth" can refer to the uplink / downlink frequency range of a frequency band. In Frequency Division Duplex (FDD), the uplink frequency range differs from the downlink frequency range. On the other hand, in Time Division Duplex (TDD), the uplink frequency range is the same as the downlink frequency range. Additionally, frequency bands can be classified into low-frequency, mid-frequency, and high-frequency bands based on the bandwidth used. For example, according to the 3GPP frequency band definition, frequency bands can be divided into three groups (low-frequency / mid-frequency / high-frequency band) based on the allocated bandwidth, as shown in Table 1.
[0133] [Table 1]
[0134]
[0135]
[0136] Frequency bands can be classified into a first frequency band having bandwidth belonging to a first frequency range, a second frequency band having bandwidth belonging to a second frequency range, and a third frequency band having bandwidth belonging to a third frequency range. Here, the second frequency range can be defined as a value having a maximum value greater than that of the first frequency range and a minimum value less than that of the third frequency range. In one embodiment, the first, second, and third frequency bands may correspond to the low-frequency, mid-frequency, and high-frequency bands defined in 3GPP, respectively. However, in another embodiment, the first, second, and third frequency bands may be defined differently from the 3GPP definitions. For example, a frequency band using 2000MHz or higher frequencies may be defined as the third frequency band.
[0137] In the embodiments of this disclosure, for convenience and ease of description, the first frequency band can be considered as a low-frequency band (LB), the second frequency band as a mid-frequency band (MB), and the third frequency band as a high-frequency band (HB). For example, LB can be approximately 700MHz to 900MHz, MB can be 1.4GHz to 2.2GHz, and HB can be 2.3GHz to 2.7GHz. In another example, the first mid-frequency band MB1 can be a band including 1.5GHz, and the second mid-frequency band MB2 can be a band including 1.7GHz. Here, the first frequency band can be considered as LB, the second frequency band can be considered as MB1, and the third frequency band can be considered as MB2 and HB. In another example, LB can be approximately 700MHz to 900MHz, MB1 can be 1.4GHz to 2.2GHz, MB2 can be 2.3GHz to 2.7GHz, and HB can be 5GHz to 6GHz. However, the criteria used for classification can be defined differently from the examples above or the criteria proposed in the 3GPP standards, and the frequency bands can be classified into four, five, or more bands.
[0138] In operations 820 and 830, according to one embodiment, the electronic device 200 can identify an antenna matching value corresponding to the frequency band currently used for communication, and can set the identified antenna matching value. For example, when the electronic device 200 performs communication in LTE frequency band 3 (1710MHz to 1880MHz), the antenna drive circuit 530 can set a matching filter so that the antenna radiator resonates in that frequency band.
[0139] In operation 840, according to one embodiment, the electronic device 200 can detect a sliding value. For example, the electronic device 200 can sense the degree of sliding of the second housing 220 from the first housing 210, and can convert the sensed degree into a numerical value to determine the sliding value. In an embodiment, the electronic device 200 can use a sliding sensor 441 to measure the distance between the first housing 210 and the second housing 220, and can determine the numerical value corresponding to the measured distance as the sliding value.
[0140] In operation 850, according to one embodiment, the electronic device 200 can sense a change in the slip value. According to one embodiment, when a change in the slip value is sensed (e.g., when the result of operation 850 is "yes"), the electronic device 200 can proceed to operation 860 and execute operation 860. According to one embodiment, when no change in the slip value is sensed (e.g., when the result of operation 850 is "no"), the electronic device 200 can return and execute operation 810.
[0141] In operations 860 and 870, according to one embodiment, the electronic device 200 can identify a correction value corresponding to the changed sliding value. The correction value may be a value used when the electronic device 200 adjusts the capacitance and / or inductance of the variable element 540. The electronic device 200 can adjust the capacitance and / or inductance of the variable element 540 based on the correction value, thereby adjusting the resonant characteristics of the second conductive portion 220-1 of the second housing 220. When adjusting the resonant characteristics of the second conductive portion 220-1, the influence of the second conductive portion 220-1 on the first conductive portion 210-1 of the first housing 210, which serves as an antenna radiator, can be reduced.
[0142] According to an embodiment, as shown in Table 2, the correction value may include a value specified for each frequency band currently used for communication.
[0143] [Table 2]
[0144]
[0145]
[0146] In Table 2, the values 1-100 indicating the sliding value can be relative values indicating the degree to which the second housing 220 slides from the first housing 210. For example, 1 can be the minimum sliding value, and 100 is the maximum sliding value.
[0147] In Table 2, the values indicating the correction values A1, A2, A3, Ak, ..., An, B1, B2, B3, etc., can be necessary values for the capacitance or inductance of the variable element 540. At least some of the correction values A1, A2, A3, Ak, ..., An, B1, B2, B3, etc., can be equal to each other.
[0148] The capacitance and / or inductance of the variable element 540 can be adjusted in various ways. One method of changing the capacitance and / or inductance is by adjusting the configuration value of a switch connected to an antenna (not shown in the figure). This is illustrated in Table 3 below.
[0149] [Table 3]
[0150]
[0151]
[0152] Correction values such as “a”, “b”, “c” to “n” can be selected to optimize antenna efficiency.
[0153] Figure 9 The results 900 of an experiment for measuring the efficiency of an antenna of an electronic device 200 according to an embodiment are shown. For example, Figure 9The result of measuring antenna efficiency could be when the capacitance of the variable element 540 is adjusted according to the movement of the second housing 220.
[0154] Figure 9 Graph 910 shows the results of measuring antenna efficiency when the capacitance of variable element 540 is adjusted according to the movement of second housing 220.
[0155] Figure 9 Graph 920 shows the results of measuring antenna efficiency when the capacitance of variable element 540 is not adjusted according to the movement of second housing 220.
[0156] exist Figure 9 In the experiment, the frequency band used by the electronic device 200 to perform communication is approximately 1800MHz, and the curve 910 may be the result of adjusting the capacitance of the variable element 540 while taking into account the approximately 1800MHz frequency band used.
[0157] When the capacitance of the variable element 540 is increased, the resonant frequency of the second conductive portion 220-1 can be decreased. The electronic device 200 can increase the capacitance of the variable element 540 so that the second conductive portion 220-1 resonates at a frequency below approximately 1800 MHz, and thus the efficiency of the antenna radiator (e.g., the first conductive portion 210-1) can be increased at approximately 1800 MHz.
[0158] When comparing graphs 910 and 920 at approximately 1800 MHz, it can be understood that the difference between the efficiency of the portion 921 in graph 920 corresponding to approximately 1800 MHz and the efficiency of the portion 911 in graph 910 corresponding to approximately 1800 MHz is approximately 5 dB or greater, as indicated by arrow 901.
[0159] Figure 10 The results 1000 of another experiment for measuring the efficiency of an antenna of electronic device 200 according to an embodiment are shown. For example, Figure 10 The results of measuring antenna efficiency are shown when the inductance of the variable element 540 has been adjusted according to the movement of the second housing 220.
[0160] Figure 10 Graph 1010 shows the results of measuring antenna efficiency when the inductance of the variable element 540 has been adjusted according to the movement of the second housing 220.
[0161] Figure 10 Graph 1020 shows the results of measuring antenna efficiency when the inductance of variable element 540 is not adjusted according to the movement of second housing 220.
[0162] exist Figure 10 In the experiment, the frequency band used by the electronic device 200 to perform communication is approximately 1900MHz, and the curve 1010 may be the result of adjusting the inductance of the variable element 540 while taking into account the approximately 1900MHz frequency band used.
[0163] When the inductance of the variable element 540 is increased, the resonant frequency of the second conductive portion 220-1 can be increased. The electronic device 200 can increase the capacitance of the variable element 540 so that the second conductive portion 220-1 resonates at a frequency higher than approximately 1900 MHz, and thus the efficiency of the antenna radiator (e.g., the first conductive portion 210-1) can be increased at approximately 1900 MHz.
[0164] When comparing graph 1010 and graph 1020 at approximately 1900 MHz, it can be understood that the difference between the efficiency of the portion 1021 in graph 1020 corresponding to approximately 1900 MHz and the efficiency of the portion 1011 in graph 1010 corresponding to approximately 1900 MHz is approximately 5 dB or greater, as indicated by arrow 1001.
