Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority from Korean Patent Application No. 10-2019-0050482 filed on April 30, 2019, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field
[0003] One or more embodiments of the present disclosure are generally directed to an antenna radiator in the form of a thin film including a plurality of layers. Background Art
[0004] With the development of mobile communication technology, electronic devices can now be configured to be freely connected to wireless / wired networks and configured to be easy to carry. For example, because portable electronic devices such as smart phones and tablet PCs include antennas for sending and receiving wireless signals, these portable electronic devices can be connected to wireless communication networks.
[0005] Electronic devices may include antennas for transmitting and receiving signals in various frequency bands. With the advancement of wireless communication technology, the frequencies used in wireless communications and the corresponding frequency bandwidth ranges have increased, and the number of antennas in devices has also increased to correspond to the increased frequency band range. However, since electronic devices are generally expected to be as small and lightweight as possible to make them more portable, the space available for installing antennas is decreasing.
[0006] The above information is provided as background information only to assist in understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above content may be applicable as prior art with respect to the present disclosure. Summary of the Invention
[0007] In electronic devices, antennas in the form of flexible printed circuit boards (FPCBs) can be installed to accommodate limited antenna mounting spaces. In this case, the FPCB antenna may not use the entire attachment area as antenna pattern space. Furthermore, since the attachment of the curved portion of the FPCB antenna may degrade over time, the performance of the FPCB antenna may degrade over time.
[0008] According to one aspect of the present disclosure, an electronic device may include: a housing; a first board located on a front surface of the housing; a second board located on a rear surface of the housing; an antenna radiator interposed between the first and second boards; and wireless communication circuitry connected to the antenna radiator and processing signals in a specific frequency band. The antenna radiator includes at least one conductive fabric layer having a resistive characteristic suitable for transmitting or receiving signals in the specific frequency band, and the at least one conductive fabric layer includes fabric plated with at least one metal.
[0009] According to another aspect of the present disclosure, an antenna radiator may include: at least one conductive fabric layer, the at least one conductive fabric layer including a fabric plated with at least one metal; and a conductive coating stacked on the at least one conductive fabric layer and configured to prevent corrosion of the at least one conductive fabric layer and transmit electrical signals outside the antenna radiator to the at least one conductive fabric layer.

In some embodiments, some of the components may be implemented as a single integrated circuit. For example, the sensor module 176 (eg, a fingerprint sensor, an iris sensor, or an illumination sensor) may be implemented as embedded in the display device 160 (eg, a display).
[0034] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), and may perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, the processor 120 may load commands or data received from another component (e.g., sensor module 176 or communication module 190) into the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134.

The input device 150 may include, for example, a microphone, a mouse, a keyboard, or a digital pen (e.g., a stylus).
[0039] The sound output device 155 can output sound signals to the outside of the electronic device 101. The sound output device 155 may include, for example, a speaker or a receiver.

The display device 160 may include, for example, a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. Depending on the embodiment, the display device 160 may include a touch circuit adapted to detect a touch or a sensor circuit adapted to measure the strength of the force caused by the touch (e.g., a pressure sensor).

According to an embodiment, the audio module 170 can obtain sound via the input device 150, or output sound via the sound output device 155 or an earphone of an external electronic device (e.g., electronic device 102) directly (e.g., wired) or wirelessly connected to the electronic device 101.
[0042] The sensor module 176 can detect an operating state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a user's state) outside the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. Depending on the embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

Depending on the embodiment, the connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).
[0045] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0047] The power management module 188 may manage power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as, for example, at least a part of a power management integrated circuit (PMIC).
[0048] The battery 189 may power at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.
[0049] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. Depending on the 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 can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a cellular 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 these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.
[0050] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., an external electronic device). Depending on the embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a PCB). Depending on the embodiment, antenna module 197 may include multiple antennas. In this case, at least one antenna suitable for the communication scheme used in a communication network (such as first network 198 or second network 199) may be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192).

Depending on the embodiment, additional components other than the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.
[0051] At least some of the above components can be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general-purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.
[0052] 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 connected to the second network 199. Each of the electronic device 102 and the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type than the electronic device 101. According to an embodiment, all or some operations to be executed on the electronic device 101 may be executed on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or execute another function or service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial response to the request, either by further processing the result or without further processing the result. To this end, for example, cloud computing technology, distributed computing technology, or client-server computing technology may be used.

Figure 7 A cross-sectional view taken along line C-C' in FIG. Figures 8A to 11B In the drawings, the same reference numerals may refer to the same components. Figures 8A to 11B , the antenna radiator 760 may be illustrated as an antenna radiator unit as it exists before being attached to an electronic device (e.g., the electronic device 400). The thicknesses of various components included in the antenna radiator 760 (e.g., the first adhesive layer 761, the second adhesive layer 765, the third adhesive layer 766, the first conductive fabric layer 762, the primer coating 768, the second conductive fabric layer 767, or the polymer compound layer 764) are not limited to the illustrated embodiment.
[0084] Reference Figure 8A and 8B , the antenna radiator 760 may include a conductive fabric layer.
[0085] According to an embodiment, Figure 8AIn the embodiment, the antenna radiator 760 (e.g., the antenna radiator 460) may include a first adhesive layer 761 (e.g., a pressure-sensitive adhesive (PSA)), a first conductive fabric layer 762 (e.g., plated nanofiber), and a conductive coating 763 (e.g., anti-tarnish polyurethane (ATU)). The first conductive fabric layer 762 may be interposed between the conductive coating 763 and the first adhesive layer 761. According to an embodiment, the antenna radiator 760 may include an adhesive protective film 769 that protects the first adhesive layer 761 and a guide film 760b that may guide the antenna radiator 760 to be attached to the correct position within the electronic device. The conductive coating 763 may be interposed between the first conductive fabric layer 762 and the guide film 760b. The first adhesive layer 761 may be interposed between the first conductive fabric layer 762 and the adhesive protective film 769. In an embodiment, when the antenna radiator 760 is attached to the electronic device (e.g., the electronic device 400), the adhesive protective film 769 and / or the guide film 760b may be removed. In another example, the guide film 760b may be omitted.
[0086] According to an embodiment, in the design of the first conductive fabric layer 762, the resistance characteristics required for the antenna radiator 760 used in the antenna can be taken into account. For example, the first conductive fabric layer 762 includes a fabric (e.g., nanofiber) and can be formed by plating the fabric with at least one metal. In a more specific example, the thread included in the fabric included in the first conductive fabric layer 762 can be plated with copper. In another embodiment, the thread included in the fabric included in the first conductive fabric layer 762 can be plated with multiple metals (e.g., nickel-copper-nickel) alternately. The first conductive fabric layer 762 can have a resistance characteristic so that the antenna radiator 760 can be used in an antenna of a specific frequency band (e.g., a frequency band of about 1 GHz or greater). In order to perform metal plating that meets the required resistance characteristics, the fabric can include an air gap of a specified size or larger or be plated with a metal of a specific thickness or larger.
[0087] According to an embodiment, in contrast to a flexible printed circuit board (FPCB), the fabric does not degrade over time. For example, in contrast to an FPCB, the first conductive fabric layer 762 does not degrade over time.
[0088] According to an embodiment, the first adhesive layer 761 may attach the antenna radiator 760 to the mounting target (e.g., the second support member 471). In an embodiment, the thickness of the first adhesive layer 761 (e.g., about 30 μm) may be greater than the thickness of the first conductive fabric layer 762 (e.g., about 15 μm).
[0089] According to an embodiment, the conductive coating 763 can prevent the first conductive fabric layer 762 from being corroded. In another example, because the conductive coating 763 is conductive, the antenna radiator 760 may not require a specific contact pad, and multiple contacts for feeding or grounding can be established at any point of the antenna radiator 760.
[0090] According to an embodiment, the guide film 760b may include one or more guide holes 760c for guiding the antenna radiator 760 to be attached to the electronic device. For example, the guide hole 760c may be formed to correspond to the position of one or more guide members included in the installation target (e.g., the second support member 471). The guide film 760b may be removed after the antenna radiator 760 is attached. Therefore, compared to the FPCB antenna that retains the guide hole after installation, the antenna radiator 760 can maintain the same or similar performance while occupying less area. In this way, the area utilization of the antenna radiator 760 can be higher than that of the FPCB antenna.
[0091] According to an embodiment, after stacking the first adhesive layer 761, the first conductive fabric layer 762, and the conductive coating 763, the antenna radiator 760 can be manufactured into the shape of a specified radiator by using a stamping process. Therefore, the entire attachment area of the antenna radiator 760 (for example, 100% of the attachment area) can be used for the radiator. Alternatively, the antenna radiator 760 can be manufactured by a molding process or a patterning process. According to an embodiment, the antenna radiator 760 can be manufactured into the shape of a specified radiator by a punching process using a laser. In this case, refer to Figure 8A or Figure 9A At least one of the first adhesive layer 761, the first conductive fabric layer 762, or the polymer compound layer 764 can be manufactured in a designated color. For example, the designated color can be distributed throughout the area to be perforated. The area to be perforated can be displayed in the designated color. Alternatively, the designated color can be a non-transparent color that responds well to laser light. The closer the designated color is to black, the better the designated color responds to laser light.
[0092] According to the embodiment, referring to Figure 8B , antenna radiator 760 except Figure 8A In addition to the structure of the back plate 680, the back plate 680 and the second support member 671 may further include a primer coating 768 (e.g., a conductive silicon coating or a conductive primer). For example, the primer coating 768 may be interposed between the conductive coating 763 and the guide film 760b. When the antenna radiator 760 is interposed between the back plate 680 and the second support member 671, as shown in FIG. Figure 6A and Figure 6BAs shown, primer coating 768 can prevent damage to antenna radiator 760 by back plate 680, which may occur during assembly of the AS and the electronic device when back plate 680 is removed from the electronic device. According to an embodiment, primer coating 768 can include conductive powder to conduct electricity.
[0093] Reference Figure 9A or Figure 9B ,Apart from Figure 8A or Figure 8B In addition to the illustrated configuration, the antenna radiator 760 may further include a polymer compound layer 764 (eg, polyethylene terephthalate (PET) or polyimide (PI)).
[0094] According to an embodiment, Figure 9A , the antenna radiator 760 may include at least one of an adhesive protective film 769, a first adhesive layer 761, a polymer compound layer 764, a second adhesive layer 765 (e.g., PSA), a first conductive fabric layer 762, a conductive coating 763, and a guide film 760b. For example, the first adhesive layer 761 may be interposed between the adhesive protective film 769 and the polymer compound layer 764. The polymer compound layer 764 may be interposed between the first adhesive layer 761 and the second adhesive layer 765. The second adhesive layer 765 may be interposed between the polymer compound layer 764 and the first conductive fabric layer 762. The first conductive fabric layer 762 may be interposed between the second adhesive layer 765 and the conductive coating 763. The conductive coating 763 may be interposed between the first conductive fabric layer 762 and the guide film 760b.
[0095] According to an embodiment, the polymer compound layer 764 can protect the antenna radiator 760 from heat damage. For example, when the polymer compound layer 764 is not present, the first conductive fabric layer 762 may repeatedly expand and contract due to changes in temperature, and thus wrinkles may occur. When wrinkles occur in the first conductive fabric layer 762, the resonant frequency of the antenna radiator 760 may change, and the changed frequency may be different from the specified resonant frequency designed for the antenna radiator 760. When the resonant frequency of the antenna radiator 760 changes, the performance of the antenna including the antenna radiator 760 may deteriorate. The polymer compound layer 764 can prevent deformation of the first conductive fabric layer 762 caused by repeated temperature changes, thereby maintaining the performance of the antenna radiator 760.
[0096] According to an embodiment, the polymer compound layer 764 can improve the flexibility of the antenna radiator 760. For example, the antenna radiator 760 can be bent into a desired shape and maintain the bent shape through the polymer compound layer 764. Therefore, using the polymer compound layer 764, the antenna radiator 760 can be more easily attached to a curved surface of an installation target (e.g., the second support member 471).
[0097] According to an embodiment, the polymer compound layer 764 may prevent the antenna radiator 760 from being deformed over time. In another embodiment, the polymer compound layer 764 may increase the tensile strength of the antenna radiator 760.
[0098] According to an embodiment, the antenna radiator 760 may include a plurality of adhesive layers (e.g., a first adhesive layer 761 and a second adhesive layer 765). For example, the first adhesive layer 761 may attach the antenna radiator 760 to the installation target. The second adhesive layer 765 may attach the polymer compound layer 764 to the first conductive fabric layer 762. In an embodiment, the thickness of the first adhesive layer 761 (e.g., approximately 30 μm) may be greater than the thickness of the first conductive fabric layer 762 (e.g., approximately 15 μm). The thickness of the first conductive fabric layer 762 (e.g., approximately 15 μm) may be greater than the thickness of the polymer compound layer 764 (e.g., approximately 12 μm). The thickness of the polymer compound layer 764 (e.g., approximately 12 μm) may be greater than the thickness of the second adhesive layer 765 (e.g., approximately 10 μm).
[0099] According to the embodiment, referring to Figure 9B ,Apart from Figure 9A In addition to the structure of the antenna radiator 760, the antenna radiator 760 may further include a primer coating 768 (eg, a conductive silicon coating or a conductive primer). For example, the primer coating 768 may be interposed between the conductive coating 763 and the guide film 760b. The primer coating 768 may be interposed between the conductive coating 763 and the guide film 760b. Figure 8B The primer coating 768 is the same or similar.

For example, the first adhesive layer 761 may be interposed between the adhesive protective film 769 and the first conductive fabric layer 762. The first conductive fabric layer 762 may be interposed between the first adhesive layer 761 and the third adhesive layer 766.

[0104] According to an embodiment, the third adhesive layer 766 may have conductive properties.

The third adhesive layer 766 may electrically connect the first conductive fabric layer 762 to the second conductive fabric layer 767.
[0105] According to an embodiment, the antenna radiator 760 includes a plurality of conductive fabric layers, thereby improving the resistance characteristics of the antenna radiator 760.

Figures 8A to 9B As shown, the antenna radiator 760 using multiple conductive fabric layers (e.g., the first conductive fabric layer 762 and the second conductive fabric layer 767) can have improved resistance characteristics (e.g., reduced resistance) compared to the case of using a single conductive fabric layer (e.g., the first conductive fabric layer 762). For example, when the first conductive fabric layer 762 and the second conductive fabric layer 767 are used together, the antenna radiator 760 can have sufficient resistance characteristics so that it can be used at a temperature below 100°C.

In another example, the antenna radiator 760 can be attached to the side frame structure 770 (e.g., side frame structure 470) through the first adhesive layer 761. The feeding portion or the grounding portion of the printed circuit board 730 (e.g., printed circuit board 450) can be connected to the connecting member 731 (e.g., a C-clip). A portion of the connecting member 731 can be connected to the contact point "E" of the antenna radiator 760.
