Description

Wearable electronic device including an antenna and a conductive elastic member

[0001] Various embodiments of the present invention relate to a wearable electronic device comprising an antenna and at least one elastic member.

[0002] The use of electronic devices such as smartphones or tablet personal computers (PCs) of bar type, foldable type, rollable type, or sliding type is increasing.

[0003] The above electronic devices are being developed into wearable forms that users can wear on parts of their bodies for portability and accessibility.

[0004] The wearable electronic device may include, for example, a watch that a user can wear on his or her wrist and / or ankle.

[0005] Wearable electronic devices that users can wear on their wrists (e.g., watches) can transmit and receive various data with other electronic devices (e.g., smartphones) using wireless communication.

[0006] The wearable electronic device may include at least one antenna (e.g., a conductive housing or antenna radiator) for performing wireless communication with another electronic device.

[0007] For example, the wearable electronic device may use a C-clip to electrically connect the conductive housing and the power supply terminal of the printed circuit board. When the C-clip is used to connect the conductive housing and the power supply terminal of the printed circuit board, the contact area of ​​the C-clip may reduce the space available for arranging other electronic components on the printed circuit board.

[0008] For example, when the conductive housing and the power supply section of the printed circuit board are connected using the above C clip, the radiation performance of the conductive housing used as an antenna may be deteriorated due to the influence of other electronic components or electrical materials placed adjacent to the conductive housing.

[0009] For example, in the wearable electronic device, once the design of the product and the arrangement structure of the conductive housing are determined, it may be difficult to improve the radiation performance of the antenna because it may be impossible to adjust the electrical length of the conductive housing used as the antenna.

[0010] Various embodiments of the present invention can provide a wearable electronic device in which a power supply unit and a conductive housing (e.g., an antenna radiator) formed on a circuit board (e.g., a printed circuit board) are electrically connected using a conductive elastic member (e.g., a pogo pin).

[0012] According to one embodiment of the present invention, a wearable electronic device may include a first conductive housing including a first opening and a second conductive housing disposed below the first conductive housing. According to one embodiment, the wearable electronic device may include a non-conductive housing surrounding at least a portion of the second conductive housing and including a second opening and a third opening, and a circuit board disposed below the non-conductive housing and including an antenna feeding portion. According to one embodiment, the wearable electronic device may include a first conductive elastic member connecting the first conductive housing and the antenna feeding portion through the second opening, and a second conductive elastic member connecting the first conductive housing and the second conductive housing through the third opening.

[0013] According to various embodiments of the present invention, by electrically connecting a power supply portion and a conductive housing formed on a circuit board using a first conductive elastic member (e.g., a pogo pin), the space for arranging other electronic components on the circuit board can be expanded.

[0014] According to various embodiments of the present invention, the electrical length of the antenna can be extended by electrically connecting a first conductive housing (e.g., an outer metal housing) and a second conductive housing (e.g., an inner metal housing) using a second conductive elastic member (e.g., a pogo pin).

The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0046] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state.

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).

[0148] Referring to FIG. 10, a wearable electronic device (200) may include a first conductive housing (310), a second conductive housing (320), a first conductive elastic member (350), and / or a second conductive elastic member (360).

[0149] According to one embodiment, the first conductive housing (310) may function as an antenna radiator of the wearable electronic device (200). For example, the first conductive housing (310) may be electrically connected to an antenna feed portion (341) of a circuit board (340) using a first conductive elastic member (350).

[0154] Referring to FIG. 11a, when the first conductive housing (310) is formed to have a first thickness (t1), the first conductive elastic member (350) can be adjusted to have a first length (L1).

[0155] Referring to FIG. 11b, when the first conductive housing (310) is formed to have a second thickness (t2), the first conductive elastic member (350) can be adjusted to have a second length (L2). For example, the second thickness (t2) disclosed in FIG. 11b can be thicker than the first thickness (t1) disclosed in FIG. 11a. For example, the second length (L2) disclosed in FIG. 11b can be shorter than the first length (L1) disclosed in FIG. 11a.

[0156] Referring to FIG. 11c, when the first conductive housing (310) is formed to have a third thickness (t3), the first conductive elastic member (350) can be adjusted to have a third length (L3). For example, the third thickness (t3) disclosed in FIG. 11c can be thinner than the first thickness (t1) disclosed in FIG. 11a. For example, the third length (L3) disclosed in FIG. 11c can be longer than the first length (L1) disclosed in FIG. 11a.

[0157] According to one embodiment, the wearable electronic device (200) according to one embodiment of the present invention can tune the electrical length of the antenna radiator by adjusting the thickness of the first conductive housing (310) and the length of the first conductive elastic member (350) even after the design is confirmed. According to various embodiments, the wearable electronic device (200) can also tune the electrical length of the antenna radiator by adjusting the thickness of the first conductive housing (310) and the length of the second conductive elastic member (360) and / or the third conductive elastic member (370) even after the design is confirmed.

[0158] According to one embodiment, the wearable electronic device (200) can tune the resonant frequency of the wireless signal by adjusting the first conductive elastic member (350) to have, for example, a first length (L1), a second length (L2), or a third length (L3).

[0159] According to one embodiment, when the first conductive elastic member (350) has a first length (L1), the resonant frequency may be as shown in the following mathematical expression 1.

[0160] [Mathematical Formula 1]

[0161] Lf = 0.1382m, L1 = 0.0069m, Lf+L1 = 0.1451m, Lf + L1 = λ / 4, λ = 0.1451 Х 4 = 0.5804m, f = c / λ = 516Mhz

[0162] For example, in the above mathematical expression 1, Lf is the electrical length of the first conductive housing (310), L1 is the length of the first conductive elastic member (350) (e.g., the first length), and c may be the speed of light.

[0163] According to one embodiment, when the first conductive elastic member (350) is reduced to a second length (L2) shorter than the first length (L1), the resonant frequency may be shifted to a higher frequency as shown in Equation 2 below. For example, the first conductive elastic member (350) may be reduced to about 4 mm less than the first length (L1).

[0164] [Equation 2]

[0165] Lf = 0.1382m, L2 = 0.0029m, Lf+L2 = 0.1411m, Lf + L2 = λ / 4, λ = 0.1411 Х 4 = 0.56044m, f = c / λ = 535Mhz

[0166] For example, in the above mathematical expression 2, Lf is the electrical length of the first conductive housing (310), L2 is the length of the first conductive elastic member (350) (e.g., the second length), and c may be the speed of light. For example, L2 may have a second length that is about 4 mm shorter than the first length (L1) of the first conductive elastic member (350). When the first conductive elastic member (350) is shortened from the first length (L1) to the second length (L2), it can be confirmed that the resonant frequency shifts to a higher frequency by about 19 MHz.

[0167] According to one embodiment, based on a change in the length (e.g., reduction) of the first conductive elastic member (350), as the resonant frequency shifts higher, it can be confirmed that the resonant frequency moves to a low band and the TRP (total radiated power: transmission output) performance is improved, as shown in Table 1 below. For example, in Table 1 below, the length of the first conductive elastic member may be reduced from about 0.69 mm to about 0.29 mm.

[0169] According to one embodiment, the wearable electronic device (200) can secure a separation distance from other electrical components (e.g., FPCB, speaker, or motor) by reducing the thickness of the first conductive housing (310). According to one embodiment, the wearable electronic device electrically connects the first conductive housing (310) and the antenna feed part (341) of the circuit board (340) using the first conductive elastic member (350) instead of the C-clip according to the comparative embodiment, thereby improving the TRP (total radiated power: transmission output) performance, as shown in Table 2 below.
