The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).
[0047] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

The description of the above-described components (e.g., the substrate layer (570), the signal line (530), the shielding layer (540), the film layer (550), the cover substrate layer (561), the adhesive layer (580)) may be equally applied to the description of the components (e.g., the substrate layer (470), the signal line (430), the shielding layer (440), the film layer (450), the cover substrate layer (461), the adhesive layer (480)) described with reference to FIGS. 1 to 12.
[0152] According to one embodiment, the circuit board (500) may include a first portion (501) and a second portion (503). The description of the first and second portions (501, 503) may be identical to the description of the first and second portions (401, 403) described with reference to FIGS. 1 to 12 . The power line (510) may be located in the first portion (501). The signal line (530) may be located in the second portion (503). The cover substrate layer (561) may be located to correspond to both the first portion (501) and the second portion (503).
[0153] According to one embodiment, the circuit board (500) may include an insulating layer (564) located in the second portion (503).

For example, the circuit board (500) may include integrally formed conductive layers (562, 563). The length (W6) of the first portion (501) of the circuit board (500) of FIG. 13 may be greater than the length (w1) of the first-first portion (401) or the length (w2) of the first-second portion (402) of the circuit board (400) of FIG. 7.

The first part (501) may be divided into a 1-1 part (501a) and a 1-2 part (501b) based on the boundary surface (P5) located inside the first part (501). The 1-1 part (501a) and the 1-2 part (501b) are arbitrarily divided for convenience of explanation, and the 1-1 part (501a) and the 1-2 part (501b) may form an integral first part (501). The conductive layers (562, 563) may be divided into a first conductive layer (562) located in the 1-1 part (501a) and a second conductive layer (563) located in the 1-2 part (501b). The sum (w6) of the length (w4) of the 1-1 part (501a) and the length (w5) of the 1-2 part (501b) may be substantially equal to the sum of the length (w1) of the 1-1 part (401) and the length (w2) of the 1-2 part (402) illustrated in FIG. 7.
