In various embodiments, at least one of the components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In various embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).


The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to an embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an 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 (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the 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., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.


The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beam-forming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199).

In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.


According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.


At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).


According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108.

For example, FIG. 24 may be a view schematically illustrating the constitution of a battery 2350 disclosed in FIGS. 23A and 23B according to an embodiment of the disclosure.


With reference to FIG. 24, the battery 2350 of the stylus pen 2300 may include a case 2451, an anode 2453, a separator 2455, and a cathode 2457. The battery 2350 may supply a power to the stylus pen 2300. The battery 2350 may include a conductive material (e.g., aluminum) at least partly.


According to an embodiment, the case 2451 may be a pouch (e.g., can) in which the anode 2453, the separator 2455, and the cathode 2457 are included. Electrolyte may be filled inside the case 2451. The case 2451 may be formed of a conductive material (e.g., metal), such as aluminum or an aluminum alloy.


According to an embodiment, the anode 2453 may include a plate formed of a conductive material, such as aluminum or copper. The separator 2455 may be formed of a non-conductive material. For example, the separator 2455 may be formed of a porous polymer membrane, such as polyethylene (PE) or polypropylene (PP). The cathode 2457 may include a plate formed of a conductive material, such as aluminum or copper. The case 2451 and the anode 2453 may be disposed to be spaced apart from each other. A capacitance property may be formed between the case 2451 and the anode 2453. The anode 2453 and the cathode 2457 may be disposed to be spaced apart from each other. The capacitance property may be formed between the anode 2453 and the cathode 2457. The anode 2453 may be disposed more adjacent to the case 2451 than the separator 2455. For example, the separator 2455 may be disposed more adjacent to the anode 2453 than the cathode 2457.


According to an embodiment, the anode 2453, the separator 2455, and the cathode 2457 may be formed to be wound or in zigzag form. For example, the anode 2453, the separator 2455, and the cathode 2457 may be wound to overlap each other. For example, the anode 2453, the separator 2455, and the cathode 2457 may be formed to be wound in the form of a jelly roll. When the anode 2453 is formed in the form of the jelly roll, it may be disposed more adjacent to the case 2451 than the separator 2455. The separator 2455 may be disposed on an inside of the anode 2453. The cathode 2457 may be disposed on an inside of the separator 2455. The separator 2455 may be disposed between the anode 2453 and the cathode 2457. The anode 2453 and the cathode 2457 may be insulated from each other through the separator 2455. The separator 2455 may be a separator film that prevents the anode 2453 and the cathode 2457 from coming in contact with each other. The separator 2455 may prevent the anode 2453 and the cathode 2457 from being shorted.


According to an embodiment, the battery 2350 may convert a chemical energy that the anode 2453 and the cathode 2457 have into an electrical energy. The anode 2453 may be an electrode into which electrons flow. Since a chemical reaction for obtaining electrons occurs on the anode 2453, the anode 2453 may be an electrode on which a reduction reaction occurs. An anode active material for anode activation may be coated on at least one surface of the anode 2453. The cathode 2457 may be an electrode from which electrons flow out. Since a chemical reaction for losing electrons occurs on the cathode 2457, the cathode 2457 may be an electrode on which an oxidation reaction occurs. A cathode active material for cathode activation may be coated on at least one surface of the cathode 2457. The anode 2453 and the cathode 2457, between which the separator 2455 is interposed, may generate current through a redox reaction.


According to an embodiment, in the battery 2350, since at least one of the case 2451, the anode 2453, and the cathode 2457, which are formed of a conductive material, is electrically connected to the ground area 320 formed on the printed circuit board 2340, the ground area of the stylus pen 2300 can be extended. At least a part of the ground area 320 formed on the printed circuit board 2340 may operate as a first radiator (e.g., first radiator 610 of FIGS. 25A or 26A) of the antenna included in the stylus pen 2300.
