[0062] The first RFIC (211) can convert a baseband signal generated by the processor (120) into an RF signal in a band used in a cellular network during transmission. During reception, the RF signal is received from the cellular network through the first antenna (215) and can be preprocessed through the first RFFE (213). The first RFIC (211) can convert the RF signal preprocessed through the first RFFE (213) into a baseband signal so that it can be processed by the processor (120).

[0063] The second RFIC (221) can convert a baseband signal generated by the processor (120) into an RF signal of a band used in a short-range communication network during transmission.

[0064] When receiving, the RF signal is received from a short-range communication network through the second antenna (225) and can be preprocessed through the second RFFE (223). The second RFIC (221) can convert the RF signal preprocessed through the second RFFE (223) into a baseband signal so that it can be processed by the processor (120).

[0065] According to one embodiment, the connector (280) may provide an electrical and / or operational connection between an electronic device (101) and an external electronic device (200) (e.g., the electronic device (102) of FIG. 1, or the external electronic device (200) of FIG. 2a) (e.g., a dongle).

[0066] The external electronic device (200) may include a processor (250) (e.g., the processor (250) of FIG. 2), a first RFIC (271) (e.g., the first RFIC (271) of FIG. 2), a first RFFE (273) (e.g., the first RFFE (273) of FIG. 2), a first antenna (275) (e.g., the first antenna (275) of FIG. 2), a second RFIC (261) (e.g., the second RFIC (261) of FIG. 2), a second RFFE (263) (e.g., the second RFFE (263) of FIG. 2), and / or a connector (290).

[0067] The first RFIC (271) can convert a baseband signal generated by the processor (250) during transmission into an RF signal in a band used in a cellular network (e.g., B31 band or B26 band). During reception, the RF signal is received from the cellular network through the second antenna (275) and can be preprocessed through the first RFFE (273). The first RFIC (271) can convert the RF signal preprocessed through the first RFFE (273) into a baseband signal so that it can be processed by the processor (250).

[0068] The second RFIC (261) can convert a baseband signal generated by the processor (250) into an RF signal in a band used in a near-field communication network during transmission. During reception, the RF signal is received from the electronic device (101) through the connector (290) and can be preprocessed through the second RFFE (263). The second RFIC (261) can convert the RF signal preprocessed through the second RFFE (263) into a baseband signal so that it can be processed by the processor (250).

[0069] According to one embodiment, the connector (290) may provide an electrical and / or operational connection between the electronic device (101) and an external electronic device (200). The connector (290) may include at least one pin and may be combined with a connector (280) included in the electronic device (101) to provide an electrical and / or operational connection. In one embodiment, the connector (290) may provide a physical connection between the external electronic device (200) and the electronic device (101). In one embodiment, the connector (290) may transmit and receive various signals for an interface between the external electronic device (200) and the electronic device (101).

[0070] As described in FIG. 2b, in a 4G mobile communication system, an external electronic device (200) supporting the B31 band or B26 band used for communication requiring a relatively high security level (e.g., a security level above the threshold security level) is not wirelessly coupled with the electronic device (101), but can be coupled using connectors (280, 290).

[0071] Since the electronic device (101) and the external electronic device (200) are physically connected via connectors (280, 290) rather than wirelessly, there may be no security issues caused by antenna radiation as described in FIG. 2a. However, in order for the electronic device (101) to transmit a signal in the B31 band or B26 band to the external electronic device (200) through the connection between the connectors (280, 290), circuit modifications to the electronic device (101) are required. For example, a divider or splitter may need to be added to the electronic device (101). Furthermore, a separate control signal may be required for the electronic device (101) to transmit a signal in the B31 band or B26 band to the external electronic device (200) through the connection between the connectors (289, 290).

[0072] FIG. 3 is a block diagram of an electronic device according to one embodiment. The contents described with reference to FIG. 1 can be applied in the same way to FIG. 3.

[0073] Referring to FIG. 3, an electronic device (300) (e.g., a smartphone) may include a main part (310), an intermediary part (320), and a communication part (330). However, not all of the illustrated components are essential components. The electronic device (300) may be implemented by more components than illustrated, or by fewer components. Furthermore, the term “part” used in the main part (310), intermediary part (320), and communication part (330) according to one embodiment may refer to a component that performs a respective role within the electronic device (300), and may mean a unit that is independent but operates together with other components.

[0074] A main part (310) according to one embodiment may include modules for performing the operation of a smartphone (e.g., a processor (120), memory (130), input module (150), sound output module (155), display module (160), audio module (170), sensor module (176), interface (177), connection terminal (178), haptic module (179), camera module (180), power management module (188), battery (189), communication module (190), subscriber identification module (196), or antenna module (197) of FIG. 1). In some embodiments, at least one of these components (e.g., connection terminal (178)) may be omitted from the main part (310), or one or more other components may be added. In some embodiments, some of these components (e.g., sensor module (176), camera module (180), or antenna module (197)) may be integrated into a single component (e.g., display module (160)). The main part (310) according to one embodiment may be referred to as a first terminal, a primary terminal, or a host device.

[0075] A communication unit (330) according to one embodiment is a device that receives and transmits RF signals in a specific frequency band, such as the B31 band or the B26 band. This device processes signals in a specific band that are not directly supported by the main unit (310) and can serve to transmit them to the main unit (310). For example, when the communication unit (330) receives a signal from a disaster communication network, it processes it internally and transmits it to the main unit (310) so that the necessary data can be used. The communication unit (330) can generally be implemented in the form of a dongle. A communication unit (330) according to one embodiment may be referred to as a dongle, a B31 dongle, an auxiliary communication device, or a communication module.

[0076] According to one embodiment, the mediation part (320) is a device that physically connects the main part (310) and the communication part (330) and can mediate the transmission and reception of RF signals. The mediation part (320) includes signal processing devices such as frequency filters and diplexers, and can appropriately convert or filter and transmit signals between the main part (310) and the communication part (330). According to one embodiment, the mediation part (320) may be referred to as an interface module, a bridge module, a bridge PBA (Printed Board Assembly), or a mediation device.

[0077] According to one embodiment, the main part (310), the mediating part (320), and the communication part (330) are not separated into independent devices and can operate together as one integrated electronic device (300). The main part (310), the mediating part (320), and the communication part (330) each perform specific roles but can form a single integrated system without being physically detachable. The main part (310) and the mediating part (320) can be physically connected through a first connecting part (340), and the mediating part (320) and the communication part (330) can be physically connected through a second connecting part (350).

[0078] In one embodiment, the electronic device (300) physically connects the main part (310) through the communication part (330) and the intermediary part (320), so compared to a case where the connection between the external electronic device (200) and the electronic device (300) is based on Bluetooth and / or Wi-Fi, it can reduce security vulnerabilities such as hacker attacks that may occur due to antenna radiation. Furthermore, since the electronic device (300) utilizes the existing circuit or configuration of the main part (310) as is without changing it, no additional circuit modification is required, and the main part (310) can be connected to the communication part (330) without a separate control signal.

[0079] The first connection part (340) according to one embodiment may be, for example, a Flat Ribbon Cable (FRC) connector. An FRC connector is a connector for connecting a Flat Ribbon Cable, which allows a flat ribbon-shaped cable to be connected to a connection port composed of multiple pins. An FRC connector includes multiple pins and can provide a flexible and simple connection method for transmitting electrical signals or data between a main part (310) and an intermediate part (320). For example, an FRC connector may be used to transmit signals between a main board corresponding to the main part (310) and an intermediate part (320) on a circuit board of an electronic device (300). However, the first connection part (340) is not limited to an FRC connector.

[0080] According to one embodiment, the second connection part (350) may be, for example, a coaxial cable connector. The intermediate part (320) and the communication part (330) may be connected via a coaxial cable connector, thereby allowing the RF signal to be transmitted stably. The coaxial cable connector plays an important role in transmitting the RF signal received from the communication part (330) to the intermediate part (320), and in processing the signal appropriately at the intermediate part (320) and transmitting it to the main part (310). However, the second connection part (350) is not limited to a coaxial cable connector.

[0081] FIG. 4 is a block diagram of a main part according to one embodiment. The description with reference to FIG. 1 and FIG. 3 can be applied in the same way to FIG. 4.

[0082] Referring to FIG. 4, a main part (310) according to one embodiment (e.g., the main part (310) of FIG. 3) may include a first antenna (410-1, 410-2), a radio frequency front end (RFFE) (420), a first radio frequency integrated circuit (RFIC) (430-1, 430-2), and a processor (440) (e.g., the processor (120) of FIG. 1).

[0083] According to one embodiment, the processor (440) may include an application processor and / or a communication processor.

[0084] According to one embodiment, the main part (310) may be connected to the first antenna (410-1, 410-2). The first antenna (410-1, 410-2) may be connected to the main part (310) through an intermediate part (320). The first antenna (410-1, 410-2) is an element responsible for transmitting and receiving RF signals of the main part (310), and the first antenna (410-1) and the first antenna (410-2) may transmit and receive signals in different frequency bands. For example, the first antenna (410-1) may transmit and receive signals in the N77, N78, N79, DRX, and GPS L1 bands. For example, the first antenna (410-2) may transmit and receive signals in the Wi-Fi 2.4GHz and 5GHz bands and the GPS L5 band. However, the signal in the frequency band that can be transmitted and received by the first antenna (410-1, 410-2) is not limited to the examples described above.

[0085] According to one embodiment, an RF signal received from the first antenna (410-1, 410-2) can be transmitted to the RFFE (420). The RFFE (420) filters and processes the signal according to the frequency band and can appropriately distribute the signal to the first RFIC (430-1, 430-2) and other wireless communication modules.

[0086] According to one embodiment, the RFFE (420) may include a power amplifier (PA) and / or a low noise amplifier (LNA) and may perform power amplification and filtering operations.

[0087] The first RFIC (430-1) may be a transceiver (TRCV) module. When transmitting, the first RFIC (430-1) can convert a baseband signal generated by the processor (440) into an RF signal in a band used in a cellular network (e.g., N77, N78, N79 bands), a DRX band, or a GPS L1 band. When receiving, the RF signal is received from the cellular network through the first antenna (410-2) and can be preprocessed through the RFFE (420). The first RFIC (430-1) can convert the RF signal preprocessed through the RFFE (420) into a baseband signal so that it can be processed by the processor (440). However, the bands that the first RFIC (430-1) can process are not limited to the examples described above.

[0088] According to one embodiment, the processor (440) may support the establishment of a communication channel in a band to be used for wireless communication with a cellular network (e.g., the second network (199) of FIG. 1), and network communication through the established communication channel. According to one embodiment, the cellular network may include a 2nd generation (2G) network, a 3rd generation (3G) network, a 4th generation (4G) network, a long term evolution (LTE) network, and / or a 5th generation (5G) network.

[0089] According to one embodiment, the first RFIC (430-2) may be a WLAN IC. When transmitting, the first RFIC (430-2) may convert a baseband signal generated by the processor (440) into an RF signal in a band used in a short-range communication network (e.g., a 2.4 GHz band and a 5 GHz band (e.g., a band used in a short-range communication network based on Wi-Fi)) or a GPS L5 band. When receiving, the RF signal may be received from the short-range communication network through the first antenna (410-1) and preprocessed through the RFFE (420). The first RFIC (430-2) may convert the RF signal preprocessed through the RFFE (420) into a baseband signal so that it can be processed by the processor (440). However, the bands that the first RFIC (430-2) can process are not limited to the examples described above.

[0090] According to one embodiment, the processor (440) can support the establishment of a communication channel in a band to be used for wireless communication with a short-range communication network (e.g., the first network (198) of FIG. 1) and network communication through the established communication channel.

[0091] FIG. 5 is a block diagram of a communication module according to one embodiment. The contents described with reference to FIG. 1, FIG. 3 and FIG. 4 can be applied in the same way to FIG. 5.

[0092] Referring to FIG. 5, a communication part (330) according to one embodiment (e.g., the communication part (330) of FIG. 3) may include a second antenna (510) and a second RFIC (530). A communication part (330) according to one embodiment may further include a modem (520).

[0093] A communication portion (330) according to one embodiment may be connected to a second antenna (510). The communication portion (330) may transmit and receive a signal (e.g., a signal in the B31 band or B26 band) having a security level higher than or equal to a threshold security level through the second antenna (510). For convenience of explanation, a signal in the B31 band or B26 band is used as an example of a signal having a security level higher than or equal to a threshold security level. However, a signal having a security level higher than or equal to a threshold security level is not limited to a signal in the B31 band or B26 band.

[0094] According to one embodiment, an RF signal received through the second antenna (510) can be transmitted to a modem (520). The modem (520) can convert the received RF signal into a digital signal. The modem (520) may include a commercial modem chipset, such as a GCT modem, for example. The GCT modem is designed to handle frequency bands used in disaster communication networks and special-purpose communication systems and can be responsible for the stable processing and conversion of such signals.

[0095] According to one embodiment, the second RFIC (530) may be a WLAN IC. The second RFIC (530) may, at the time of transmission, convert an RF signal of a band used in a local area communication network (e.g., a 2.4 GHz band or a 5 GHz band (e.g., a band used in a local area communication network based on Wi-Fi)) received from the main part (310) through the intermediate part (320) into an RF signal of the B31 band or B26 band. Upon reception, an RF signal of the B31 band or B26 band (e.g., a signal with a security level above a threshold security level) is received from a local area communication network through the second antenna (510) and can be converted into a digital signal through the modem (520), and the second RFIC (530) can convert the digital signal converted by the modem (520) into an RF signal of a band used in the local area communication network (e.g., a 2.4 GHz band or a 5 GHz band (e.g., a band used in a local area communication network based on Wi-Fi)). However, the bands that the second RFIC (530) can process are not limited to the examples described above.

[0096] FIG. 6 is a block diagram of an electronic device according to one embodiment. The description with reference to FIG. 1, FIG. 3 to FIG. 5 can be substantially applied to FIG. 6.

[0097] Referring to FIG. 6, an electronic device (300) according to one embodiment (e.g., the electronic device (300) of FIG. 3) (e.g., a smartphone) may include a main part (310) (e.g., the main part (310) of FIG. 3 or FIG. 4), an intermediate part (320) (e.g., the intermediate part (320) of FIG. 3), and a communication part (330) (e.g., the communication part (330) of FIG. 3 or FIG. 5).

[0098] In one embodiment, the main part (310) and the intermediate part (320) may be electrically connected through a first connection part (340) (e.g., the first connection part (340) of FIG. 3), and the intermediate part (320) and the communication part (330) may be electrically connected through a second connection part (350) (e.g., the second connection part (350) of FIG. 3). For example, the first connection part (340) may include a first cable (340-3), a first-1 port (340-1) connected to a connector located at one end of the first cable (340-3), and a first-2 port (340-2) connected to a connector located at the other end of the first cable (340-3). The first-1 port (340-1) may be located at one end of the main part (310), and the first-2 connector (340-2) may be located at one end of the intermediate part (320). The first cable (340-3) according to one embodiment may be, for example, a flexible RF cable (FRC).

[0099] In one embodiment, the first connection part (340) may include a first terminal for signal transmission and reception with the first antenna (410-1) and a second terminal for signal transmission and reception with the second antenna (410-2).

[0100] According to one embodiment, the communication portion (330) and the intermediary portion (320) may be physically connected through a second connection portion (350), and the intermediary portion (320) and the communication portion (330) may be electrically connected through the second connection portion (350). For example, the second connection portion (350) may include a second cable (350-3), a second-1 port (350-1) connected to a connector located at one end of the second cable (350-3), and a second-2 port (350-2) connected to a connector located at the other end of the second cable (350-3).

According to one embodiment, the second cable (350-3) may be a coaxial cable.

[0101]

[0102] In one embodiment, the communication portion (330) can convert an RF signal of a first frequency band (e.g., B31 band or B26 band) into an RF signal of a second frequency band (e.g., 5 GHz band). At this time, a low-pass filter (LPF) is used as the frequency filter (610) to remove the RF signal of the second frequency band (e.g., 5 GHz) obtained through the first antenna (410-2) and transmit only the RF signal of the third frequency band (2.4 GHz band) to the main portion (310). The low-pass filter may be a filter that passes only frequency components below a set cutoff frequency and blocks frequency components above it. The cutoff frequency of the frequency filter (610) according to one embodiment may be set to a value between approximately 2.4 GHz and approximately 6 GHz.

[0103] In another embodiment, the communication portion (330) may convert an RF signal of a first frequency band (e.g., B31 band or B26 band) into an RF signal of a third frequency band (e.g., 2.4 GHz band). In this case, the frequency filter (610) may use a high-pass filter (HPF) instead of a low-pass filter (LPF), and may remove the RF signal of the third frequency band (e.g., about 2.4 GHz) obtained through the first antenna (410-2) and transmit only the RF signal of the second frequency band (e.g., about 5 GHz band) to the main portion (310). The high-pass filter may be a filter that passes only frequency components above a set cutoff frequency and blocks frequency components below it.

[0104] Below, for convenience of explanation, an RF signal of a first frequency band (e.g., B31 band or B26 band) in the communication part (330) is converted into an RF signal of a second frequency band (e.g., 5GHz band), and a low-pass filter is used as the frequency filter (610) for the explanation.

[0105] According to one embodiment, the intermediate section (320) may include a frequency filter (610) and a diplexer (620). The frequency filter (610) is connected between the first antenna (410-2) and the diplexer (620), and the diplexer (620) may be connected to the frequency filter (610), the first connection section (340), and the second connection section (350), respectively. According to one embodiment, the frequency filter (610) may be a low-pass filter. The diplexer (620) may mix or separate signals of different frequency bands. According to one embodiment, the intermediate section (320) may further include an attenuator (630). The attenuator (630) may be connected between the diplexer (620) and the second connection section (350). The attenuator (630) can adjust the strength of the RF signal transmitted from the communication part (330) so that it can be transmitted to the main part (310) with an appropriate signal strength. The attenuator (630) can support stable communication by adjusting the signal strength so that the signal is not distorted during transmission and reception.

[0106] According to one embodiment, the first antenna (410-1) (e.g., the first antenna (410-1) of FIG. 4) and the first antenna (410-2) (e.g., the first antenna (410-2) of FIG. 4) each transmit and / or receive signals of different frequency bands, and only the signal received by the first antenna (410-2) can be processed through the frequency filter (610). The signal received by the first antenna (410-1) is not input to the frequency filter (610) and can be directly transmitted to the main part (310).

[0107] Upon reception, the communication portion (330) according to one embodiment converts the RF signal of the first frequency band (e.g., B31 band or B26 band) entering through the second antenna (510) (e.g., the second antenna (510) of FIG. 5) into an RF signal of the second frequency band (e.g., 5 GHz band) and can transmit the RF signal of the second frequency band to the diplexer (620) through the second connection portion (350). The RF signal entering through the first antenna (410-2) according to one embodiment is transmitted to the frequency filter (610), and the frequency filter (610) filters out the RF signal of the second frequency band (e.g., 5 GHz band) and can transmit only the RF signal of the other third frequency band (e.g., 2.4 GHz band) or other frequency band to the diplexer (620). A diplexer (620) according to one embodiment can combine an RF signal of a second frequency band (e.g., 5 GHz band) received through a second connection part (350) with an RF signal of a third frequency band (e.g., 2.4 GHz band) or another frequency band received from a frequency filter (610), and can transmit the combined signal to a main part (310) through a first connection part (340).

[0108] A combined signal according to one embodiment enters the main part (310) through the first connection part (340) and can be transmitted to the first RFIC (430-2) (e.g., the first RFIC (430-2) of FIG. 4) after passing through the RFFE (420) (e.g., the RFFE (420) of FIG. 4). The RFIC (430-2) may be a WLAN IC, and the first RFIC (430-2) may convert the combined signal into a baseband signal so that it can be processed by a processor (440) (e.g., the processor (440) of FIG. 4). Through this, the processor (440) can process the signal received from the second antenna (510) of the communication part (330) and the signal received from the first antenna (410-2).

[0109] When transmitting, the main part (310) according to one embodiment can transmit a digital signal generated by the processor (440) to the first RFIC (430-2). The first RFIC (430-2) may be a WLAN IC and may convert the digital signal into an RF signal of a second frequency band (e.g., 5 GHz band) or a third frequency band (e.g., 2.4 GHz band). The converted signal may be processed through the RFFE (420) and then transmitted to the diplexer (620) of the intermediate part (320) through the first connection part (340).

[0110] According to one embodiment, the diplexer (620) can process signals to be transmitted through the first antenna (410-2) and signals to be transmitted to the communication section (330). Among the RF signals of the second frequency band (5GHz band) or the third frequency band (2.4GHz band) transmitted from the main section, the diplexer (620) can transmit the RF signal of the third frequency band (2.4GHz band) to the first antenna (410-2) through the frequency filter (610) and transmit the RF signal of the corresponding frequency band. Meanwhile, the RF signal of the second frequency band (5GHz band) can be transmitted to the communication section (330) through the second connection section (350).

[0111] According to one embodiment, the second RFIC (530) of the communication part (330) can convert an RF signal of the second frequency band (5 GHz band) received through the second connection part (350) into a signal of the first frequency band (e.g., B31 band or B26 band). The signal of the first frequency band (e.g., B31 band or B26 band) converted by the second RFIC (530) can be transmitted externally through the second antenna (510) via the modem (520). In this way, a signal generated in the main part (310) can be converted into an RF signal of the first frequency band (e.g., B31 band or B26 band) through the communication part (330) and transmitted.

[0112] FIG. 7 is a diagram illustrating the connection structure between the antenna module of the main part and the intermediate module according to one embodiment. The description with reference to FIG. 1, FIG. 3 to FIG. 6 can be substantially applied to FIG. 7.

[0113] Referring to FIG. 7, a main part (310) according to one embodiment (e.g., the main part (310) of FIG. 3, FIG. 4 or FIG. 6) may include a main PCB (not shown) on which a processor is placed and a sub PCB (Printed Circuit Board) (700) connected to a first antenna (410-1, 410-2). The sub PCB (700) may include the first antenna (410-1, 410-2) (e.g., the first antenna (410-1, 410-2) of FIG. 4 or FIG. 6).

[0114] A sub-PCB (700) according to one embodiment may be connected to an intermediate portion (320) (e.g., the intermediate portion (320) of FIG. 3 or FIG. 6) through a first connection portion (340) (e.g., the first connection portion (340) of FIG. 3, the first connection portion (340) of FIG. 6).

[0115] According to one embodiment, the first antenna (410-2) can receive and transmit RF signals in the 5GHz and 2.4GHz bands. The first antenna (410-2) can be connected to a frequency filter (610) of the intermediate part (320) (e.g., the frequency filter (610) of FIG. 6). The RF signal received through the first antenna (410-2) is transmitted to the frequency filter (610), and the frequency filter (610) can filter the signal in the second frequency band (e.g., 5GHz) and transmit the RF signal in the third frequency band (e.g., 2.4GHz) to a diplexer (620) (e.g., the diplexer (620) of FIG. 6). The diplexer (620) serves to combine or separate RF signals of different frequency bands, thereby allowing the signal received from the main part (310) and the signal received from the communication part (330) (e.g., the communication part (330) of FIG. 3, FIG. 4 or FIG. 6) to be separated or combined.

[0116] The intermediate section (320) according to one embodiment may include an attenuator (630) (e.g., the attenuator (630) of FIG. 6) and may adjust the strength of the signal through the attenuator (630). The attenuator (630) may reduce the signal strength when the signal becomes excessively strong so that distortion does not occur when transmitted to the main section (310). For example, the attenuator (630) may attenuate the signal at a level of about 5 dB.

[0117] According to one embodiment, the second connection part (350) is responsible for the connection between the mediation part (320) and the communication part (330), and can enable an RF signal received from the outside to be transmitted to the mediation part (320).

[0118] FIG. 8 is a drawing illustrating an exemplary form connecting a main part and an intermediate part. The description with reference to FIG. 1, FIG. 3 through FIG. 7 can be substantially applied to FIG. 8.

[0119] Referring to FIG. 8, the connection structure between the main part (310) (e.g., the main part (310) of FIG. 3, FIG. 4, FIG. 6 or FIG. 7) and the intermediate part (320) (e.g., the intermediate part (320) of FIG. 3, FIG. 6 or FIG. 7) according to one embodiment is not implemented in only a specific way, but various structural variations may be possible. In other words, the connection form shown in FIG. 8 is only one embodiment, and various other connection methods may also be applied.

[0120] In the form illustrated in FIG. 8, the antenna module (700) of the main part (310) according to one embodiment (e.g., the antenna module (197) of FIG. 1 or the antenna module (700) of FIG. 7) and the intermediate part (320) may be physically closely coupled. For example, the antenna module (700) may be electrically connected to the intermediate part (320) through a first connection part (340) (e.g., the first connection part (340) of FIG. 3, the first connection part (340) of FIG. 6 or the first connection part (340) of FIG. 7).

[0121] According to one embodiment, the intermediate portion (320) may be designed to be positioned to fit the side or a portion of the surface of the antenna module (700) of the main portion (310) so as to transmit signals while physically in close contact with each other. For example, the intermediate portion (320) may be positioned to span the top of the antenna module (700) of the main portion (310) and may form a rigid structural connection. The intermediate portion (320) may be positioned to wrap around a portion of the antenna module (700) of the main portion (310). In this case, the intermediate portion (320) may be exposed to the outside through an opening formed in the rear cover (312) of the main portion (310), making it easy to electrically connect with the communication portion (330). This coupling method may contribute to minimizing signal interference or signal loss by keeping the signal transmission path between the intermediate portion (320) and the main portion (310) short.

[0122] FIG. 9 is a diagram illustrating an example of a method in which a main part, an intermediate part, and a communication part constitute a single electronic device according to one embodiment.

Additionally, the electronic device (300) may include a back-cover (312) located in a rear area without a display of the main part (310), and a front rugged case (311) covering a front area where the display of the main part (310) is located.

[0124] According to one embodiment, the intermediary part (320) is positioned to penetrate the rear cover (312) of the main part (310) and can be connected to the antenna module of the main part (310) (e.g., antenna module (197) of FIG. 1, antenna module (700) of FIG. 7 or FIG. 8). At the same time, the intermediary part (320) can be connected to the communication part (330) through a second connection part (350) (e.g., second connection part (350) of FIG. 3, second connection part (350-1, 350-2) of FIG. 6).

[0125] According to one embodiment, the main part (310), the intermediate part (320), and the communication part (330) can be combined in an integrated structure. For example, the intermediate part (320) and the communication part (330) can form an integrated electronic device (300) without being detachable from the main part (310). However, the configuration shown in FIG. 9 is merely a specific embodiment, and various variations are possible. For example, the location or method of combination of the intermediate part (320) and the method of connection between each terminal may vary depending on design requirements.
