Description

Technical Field

[0001] The present disclosure generally relates to an antenna and a foldable electronic device including the antenna. Background Art

[0002] One of the current trends in mobile electronic devices is that users generally demand thinner device bodies. Specifically, the thickness of electronic devices is being reduced as much as possible. Furthermore, these electronic devices are being developed to increase their rigidity and improve them in other ways, which will differentiate them in the market. These electronic devices are also being developed with various shapes that depart from the traditional uniform rectangular form. One example of this development is foldable electronic devices with large-screen displays that can be folded when not in use. Summary of the Invention

[0003] Technical issues

[0004] A foldable electronic device may include a first shell (or first shell structure) and a second shell (or second shell structure) connected to each other by a hinge module (or hinge structure) interposed therebetween. In the foldable electronic device, the hinge module allows each of the first shell and the second shell to rotate from 0 degrees to 360 degrees relative to each other. The device can be folded inward, wherein the display is disposed inside the device when folded, or folded outward, wherein the display is disposed outside the device when folded. The foldable electronic device may include a flexible display that is configured to substantially cover both the first shell and the second shell in an open (i.e., unfolded) state, wherein the first shell and the second shell are 180 degrees relative to each other.

[0005] The foldable electronic device includes at least one antenna for communication. Regardless of how the device is folded, the antenna needs to meet the required radiation performance. However, in the unfolded state of the foldable electronic device (wherein the rear surfaces of the first shell and the second shell face each other so that the display is exposed to the outside), the radiation performance may be reduced due to various conductive members that shield the antenna. These conductive members may include a conductive layer of the display (e.g., a copper plate), a conductive mechanical structure (e.g., a conductive support member or a conductive bracket) provided in the electronic device near the antenna, or a conductive electrical structure (e.g., an interface connector port, a speaker assembly, or a microphone module) provided in the electronic device near the antenna.

According to an embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input device 150, a sound output device 155, a display device 160, an audio module 170, a sensor module 176, an interface 177, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the display device 160 or the camera module 180) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. 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).

[0041] 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.

[0049] 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.

[0050] The interface 177 may support one or more specific protocols to be used to connect the electronic device 101 directly (e.g., wired) or wirelessly to an external electronic device (e.g., the electronic device 102). Depending on the embodiment, the interface 177 may include, for example, a High-Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital (SD) card interface, or an audio interface.

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).

[0052] 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.

[0053] The camera module 180 may capture still images or moving images. Depending on the embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

[0054] 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).

[0055] 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.

[0056] 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.

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.

Signals or power can then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna.

[0058] 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.

[0059] 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.

According to one embodiment, in the folded state of the electronic device 200 (where the second surface 212 of the first housing 210 and the fourth surface 222 of the second housing 220 face each other (e.g., contact each other)), the second conductive pad 421 may be disposed in a position such that it is electrically coupled to the first conductive pad 411, thereby being capacitively coupled to the first conductive pad 411.

In this case, the radiation performance of an antenna using only the conductive pattern 410 may be reduced due to an increase in return loss or a shift to an undesirable frequency band caused by the conductive layer (e.g., a copper plate) of the display 230. In addition, the radiation performance of an antenna using only the conductive pattern 410 may be reduced due to conductive members, such as a conductive mechanical structure (e.g., a conductive support member or a conductive bracket) or a conductive electrical structure (e.g., an interface connector port, a speaker assembly, or a microphone module) provided near the antenna.

[0101] Reference Figure 10 In operation 1011, the electronic device (eg, Figure 9a A processor (eg, Figure 9a The processor 280 in the embodiment can detect whether the electronic device 200 is in the folded state.

Therefore, the conductive pattern 410 can be used as a radiator of the antenna together with the conductor 420. According to one embodiment, the processor can use a Hall sensor provided in one of the first housing 210 and the second housing 220 to detect the folding state of the electronic device 200 (for example, Figure 5a In another embodiment, the processor 280 may use a proximity sensor and / or an ultrasonic sensor provided in one of the first housing 210 and the second housing 220 to detect the folded state of the electronic device 200.

According to one embodiment, the processor 280 may detect the folded state of the electronic device 200, periodically control the switching device S, and detect the antenna return loss of each inductor L through the coupler 430. Therefore, the processor 280 may select the optimal inductor L based on the folded position of the electronic device so that the antenna can have optimal radiation performance. In other words, when the capacitance value between the conductive pads changes due to the folded position of the electronic device, the processor 280 may change the selection of the inductor L.
