Description

wearable electronic devices

[0001] Embodiments of the present disclosure relate to a wearable electronic device capable of improving antenna performance.

[0002] A wearable electronic device may include a flexible printed circuit board (FPCB) and a printed circuit board (PCB) on which antennas and electronic components for transmitting and receiving wireless signals are arranged. An antenna pattern may be arranged on an antenna carrier of the wearable electronic device.

[0003] The above-described material is provided solely as background information to aid in understanding the embodiments of the present disclosure. No determination has been made, and no claims are made, as to whether any of the above material constitutes prior art in connection with the present disclosure.

[0004] As the functions of wearable electronic devices (e.g., true wireless stereo (TWS) wireless earphones) become more advanced, they may include various sensor components, including high-performance speakers, multiple microphones (e.g., inner / outer mics), sensors for various status detection or bio-signal acquisition (e.g., proximity sensors, electrode sensors, bio-sensors), and sensors for touch detection (e.g., touch sensors). Depending on the design characteristics of the wearable electronic device, flexible printed circuit boards (FPCBs) and printed circuit boards (PCBs) are complexly connected and positioned, and parasitic resonance may occur due to the length of the flexible printed circuit board (FPCB), which may deteriorate antenna performance.

[0005] Since the antenna pattern of a wearable electronic device is positioned only on the antenna carrier, the antenna pattern area may be small, resulting in low antenna performance. The narrow internal space of a wearable electronic device may make it difficult to secure a sufficient area for the antenna pattern. The small area of ​​the antenna pattern may degrade antenna performance, resulting in reduced data transmission performance and audio interruption. To ensure that the antenna pattern operates without degradation due to a flexible printed circuit board (FPCB), the grounding of the FPCB may be strengthened to act as ground. The antenna pattern of a wearable electronic device may be positioned independently, avoiding the FPCB. A sufficient separation distance must be secured between the antenna pattern and the FPCB. If the FPCB is not grounded enough to act as ground, parasitic resonance may occur due to the FPCB, resulting in low antenna performance.

[0006] An embodiment of the present disclosure can provide a wearable electronic device in which an antenna pattern and a ground portion of a flexible printed circuit board (FPCB) are electrically connected together to one antenna feed point disposed in the wearable electronic device, so that the antenna pattern and the flexible printed circuit board (FPCB) can be used (e.g., utilized) together as an antenna radiator.

[0007] The technical challenges addressed in this document are not limited to the technical challenges mentioned above, and may be expanded upon without departing from the spirit and scope of the present disclosure. Additional technical challenges not mentioned herein will be readily apparent to those skilled in the art, as described below.

[0008] A wearable electronic device according to one embodiment of the present disclosure may include a circuit board having a wireless communication circuit arranged thereon, an antenna pattern arranged on an antenna carrier and electrically connected to the wireless communication circuit through an antenna feed point, and a flexible circuit board having a ground portion arranged thereon. The flexible circuit board may be connected to the circuit board. The antenna pattern may be arranged to be coupled with at least a portion of the ground portion.

[0009] According to one embodiment of the present disclosure, a wearable electronic device may electrically connect an antenna pattern and a ground portion (e.g., a ground line, a ground pattern) of a flexible printed circuit board (FPCB) to a single antenna feed point. This allows antenna performance to be improved by using (e.g., utilizing) the antenna pattern and the flexible printed circuit board together as an antenna radiator.

[0010] In one embodiment of the present disclosure, a wearable electronic device includes an antenna pattern and a ground portion (e.g., a ground line, a ground pattern) of a flexible printed circuit board (FPCB) electrically connected to one antenna feed point, so that the flexible printed circuit board can be used (e.g., utilized) as a ground line (e.g., a ground pattern) for the antenna to operate as an inverted F antenna (IFA).

[0011] According to one embodiment of the present disclosure, a wearable electronic device has an antenna pattern and a ground portion (e.g., a ground line, a ground pattern) of a flexible printed circuit board (FPCB) electrically connected to one antenna feed point, thereby eliminating resonance due to a long length of the flexible printed circuit board (FPCB) and increasing the total area of ​​the antenna radiator.

[0012] According to one embodiment of the present disclosure, a wearable electronic device can reduce radiation of a wireless signal by the flexible printed circuit board (FPCB) by electrically connecting an antenna pattern and a ground portion (e.g., a ground line, a ground pattern) of a flexible printed circuit board (FPCB) to one antenna feed point, and can reduce interference caused by a user's human body by using (e.g., utilizing) the antenna pattern as a main radiator.

[0090] Figure 8 is a drawing showing an antenna pattern arranged on an antenna carrier and a ground pattern of a flexible printed circuit board (FPCB) so as to be coupled.

[0091] Referring to FIGS. 5 and 8, according to one embodiment, a second portion (420) (e.g., a driving circuit portion or a stem portion) of a wearable electronic device (400) may include an antenna pattern (500) formed on an antenna carrier (421). The second portion (420) (e.g., a driving circuit portion or a stem portion) may include an antenna feed point (510) (e.g., a feed portion), a flexible circuit board (600, FPCB), and a circuit board (700, PCB).

[0092] According to one embodiment, an antenna pattern (500) (e.g., antenna radiation pattern) and a flexible circuit board (600, FPCB) may be electrically connected to one antenna feed point (510) of a second part (420) (e.g., driving circuit portion, stem portion) of a wearable electronic device (400). For example, a conductive connecting member (e.g., C-clip) of a circuit board (700, PCB) may be electrically connected to the feed point (510) so that a wireless communication circuit and the antenna pattern (500) are electrically connected.

[0093] For example, the antenna pattern (500) may include a first branch (520, branch1) and a second branch (530, branch2). The antenna feed point (510) and the first branch (520) may be electrically directly connected. The antenna feed point (510) and the antenna pattern (500) may be electrically directly connected with the first branch (520) interposed therebetween. For example, an antenna radiator may be formed by the antenna pattern (500) and the first branch (520). For example, the first branch (520) may electrically connect the antenna feed point (510) and the antenna pattern (500) to adjust the resonant frequency of the antenna pattern (500).

[0094] For example, the antenna feed point (510) and the second branch (530) may be electrically directly connected. The second branch (530) may be arranged (e.g., connected) to a flexible circuit board (600, FPCB) in a coupling form. The antenna feed point (510) and the flexible circuit board (600, FPCB) may be connected in a coupling form with the second branch (530) therebetween. An insulating layer is formed on the outer surface of the flexible circuit board (600, FPCB). The second branch (530) and the flexible circuit board (600, FPCB) may be arranged adjacently (e.g., overlapped) with the insulating layer therebetween, so that the antenna feed point (510) and the flexible circuit board (600, FPCB) may be connected in a coupling form.

[0098] For example, the first connection portion (531) of the second branch (530) may be electrically directly connected to the antenna feed point (510). For example, one side of the first connection portion (531) of the second branch (530) may be electrically connected to the antenna feed point (510), and the other side of the first connection portion (531) may be electrically connected to the second connection portion (532).

[0099] For example, one side of the second connection portion (532) of the second branch (530) may be electrically connected to the first connection portion (531), and the other side of the second connection portion (532) may be electrically connected to the third connection portion (533). For example, the second connection portion (532) of the second branch (530) may be arranged to overlap (e.g., overlap with a certain interval) a ground portion (610) (e.g., a ground line, a ground pattern) arranged on a flexible circuit board (600, FPCB). For example, the ground portion (610) (e.g., a ground line, a ground pattern) may be formed in a long bar shape along the longitudinal direction of the flexible circuit board (600, FPCB). For example, a coupling may be formed by overlapping the second connection portion (532) of the second branch (530) and the ground portion (610) (e.g., ground line, ground pattern) arranged on the flexible circuit board (600, FPCB). The second connection portion (532) and the ground portion (610) (e.g., ground line, ground pattern) are coupled, so that the second branch (530) and the flexible circuit board (600, FPCB) may be connected in the form of a coupling.

[0100] For example, one side of the third connection portion (533) of the second branch (530) may be electrically connected to the second connection portion (532), and the other side may be connected to the flexible circuit board (600, FPCB) in a coupling form. For example, the third connection portion (533) of the second branch (530) may be arranged to overlap with the ground portion (610) arranged on the flexible circuit board (600, FPCB). For example, the ground portion (610) may be formed to have a relatively large area on a portion of the flexible circuit board (600, FPCB). For example, a coupling is formed by overlapping the third connection portion (533) of the second branch (530) and the ground portion (610) arranged on the flexible circuit board (600, FPCB), so that the second branch (530) and the flexible circuit board (600, FPCB) can be connected in the form of a coupling.

For example, at least a portion of the second branch (530) and at least a portion of the flexible circuit board (600, FPCB) may be directly electrically connected and utilized as a ground.

[0102] A wearable electronic device (400) according to one embodiment of the present disclosure can operate as an antenna radiator by electrically connecting an antenna pattern (500) and a ground portion (610) (e.g., ground line, ground pattern) of a flexible circuit board (600, FPCB) to one antenna feed point (510).

[0103] In the description referring to Fig. 9, it was described that the antenna pattern (500) and the flexible circuit board (600, FPCB) are electrically connected in a coupling form. However, this is not limited thereto, and a part of the insulating layer on the outer surface of the flexible circuit board (600, FPCB) may be removed, and the antenna pattern (500) and the ground portion (610) (e.g., ground line, ground pattern) of the flexible circuit board (600, FPCB) may be electrically directly connected.

[0104] According to one embodiment, a portion of the insulating layer on the outer surface of the flexible circuit board (600, FPCB) is removed, and the first connection portion (531) of the second branch (530) and the ground portion (610) (e.g., ground line, ground pattern) of the flexible circuit board (600, FPCB) can be electrically directly connected.

[0106] According to one embodiment, a portion of the insulating layer on the outer surface of the flexible circuit board (600, FPCB) may be removed, and the third connection portion (533) of the second branch (530) and the ground portion (629) of the flexible circuit board (600, FPCB) may be electrically directly connected.

[0107] Figure 10 is a drawing showing an antenna pattern electrically connected to an antenna feed point and operating as an antenna radiator.

[0108] Referring to FIG. 10, according to one embodiment, an antenna carrier (e.g., antenna carrier (421) of FIG. 5), an antenna pattern (500), a flexible circuit board (600, FPCB), and a circuit board (700, PCB) may be placed on a second part (e.g., the second part (420) of FIG. 5, a driving circuit unit, or a stem unit) of a wearable electronic device.

[0109] According to one embodiment, an antenna pattern (500) may be formed on an antenna carrier (e.g., an antenna carrier (421) of FIG. 5) of a second portion (e.g., a second portion (420) of FIG. 5, a driving circuit portion, or a stem portion) of a wearable electronic device. For example, a first branch (1020, branch1) may be fed through an antenna feed point (510). The antenna feed point (510) may be electrically connected to a circuit board (700, PCB). The antenna pattern (500) may be electrically connected to a wireless communication circuit and may be used as an antenna radiator.

[0110] Figure 11 is a drawing showing a flexible printed circuit board (FPCB) connected to an antenna feed point and used (e.g., utilized) as an antenna radiator.

[0111] Referring to FIG. 11, according to one embodiment, a second branch (1120, branch2), a flexible circuit board (600, FPCB), and a circuit board (700, PCB) may be disposed in a second portion (e.g., the second portion (420) of FIG. 5, the driving circuit portion, or the stem portion) of the wearable electronic device. For example, an antenna carrier (e.g., the antenna carrier (421) of FIG. 5) and an antenna pattern (e.g., the antenna pattern (500) of FIG. 10) may be disposed in the second portion (420) of the wearable electronic device (e.g., the driving circuit portion, or the stem portion).

[0112] According to one embodiment, the antenna feed point (510) may be electrically connected to a second branch (1120, branch 2). The second branch (1120, branch 2) may be arranged to overlap with a ground portion of the flexible circuit board (600) (e.g., the ground portion (610) of FIG. 9). The antenna feed point (510) and the flexible circuit board (600) may be connected in a coupling form.

[0113] As shown in FIGS. 10 and 11, an antenna pattern (500) can be electrically connected to an antenna feed point (510), and a flexible circuit board (600) can be connected to the antenna feed point (510) in a coupling form to form an antenna radiator.

[0114] Referring to FIG. 9, a wearable electronic device (400) according to one embodiment of the present disclosure may have an antenna pattern (500) and a ground portion (610) (e.g., a ground line, a ground pattern) of a flexible circuit board (600, FPCB) electrically connected together to a single antenna feed point (510). Through this, antenna performance can be improved by using (e.g., utilizing) the antenna pattern (500) and the flexible circuit board (600, FPCB) together as an antenna radiator.

[0115] For example, since the antenna pattern (500) and the ground portion (610) (e.g., ground line, ground pattern) of the flexible circuit board (600, FPCB) are electrically connected to one antenna feed point (510), the flexible circuit board (600, FPCB) can be used (e.g., utilized) as a ground (e.g., ground line, ground pattern) for the antenna pattern (500) to operate as an IFA (Inverted F Antenna).

[0116] For example, the antenna pattern (500) and the ground portion (610) (e.g., ground line, ground pattern) of the flexible circuit board (600, FPCB) are electrically connected to one antenna feed point (510), thereby eliminating resonance due to the long length of the flexible circuit board (600, FPCB) and increasing the total area of ​​the antenna radiator.

[0117] For example, the antenna pattern (500) and the ground portion (610) (e.g., ground line, ground pattern) of the flexible circuit board (600, FPCB) are electrically connected to one antenna feed point (510), thereby reducing radiation of a wireless signal by the flexible circuit board (600, FPCB), and by using (e.g., utilizing) the antenna pattern (500) as a main radiator, interference by the user's human body can be reduced.

[0118] Antenna Efficiency TRP (Total Radiation Power) Comparison Example Antenna - 18 dB - 6.2 dB Antenna of the present invention - 15.5 dB - 3.5 dB Improvement 2.5 dB - 2.7 dB

[0119] Referring to Table 1, by using (e.g., utilizing) an antenna pattern (500) and a flexible circuit board (600, FPCB) together as an antenna radiator, the antenna efficiency can be improved by 2.5 dB compared to the antenna of the comparative example.

[0120] In addition, by using (e.g., utilizing) the antenna pattern (500) and the flexible circuit board (600, FPCB) together as an antenna radiator, the total radiation power (TRP) can be improved by 2.7 dB compared to the antenna of the comparative example.
