[0022] The following detailed description of the present technology refers to the accompanying drawings, which illustrate specific embodiments in which the present technology can be practiced. These embodiments are intended to describe various aspects of the present technology in sufficient detail to enable those skilled in the art to practice the technology. Other embodiments may be utilized and changes may be made without departing from the scope of the present invention. Therefore, the following detailed description will not be considered as limiting. The scope of the present technology is defined by the appended claims together with the full range of equivalents to which such claims are assigned.

[0023] Relational and / or directional terms such as "above," "below," "up," "upper," "upward," "down," "lower," "top," "bottom," "outer," "inner," and the like may be used throughout this specification, along with directional terms such as "horizontal" and "vertical." These terms retain their generally accepted definitions and are used with reference to embodiments of the technology and their positions, directions, and orientations as shown in the accompanying drawings. Embodiments of the technology may be otherwise positioned and oriented or moved in other directions. Accordingly, these terms do not limit the scope of the technology.

[0024] Embodiments of the present technology relate to an electronic device that can be worn on a user's wrist and wirelessly communicate with other devices, systems, and networks. The electronic device can be a fitness watch, a wrist-worn smart phone, a wrist-worn navigation device, or other wearable multifunctional electronic device including a housing and a wristband, a strap, or other attachment mechanism. Although the electronic device is typically worn on the wrist, it can also be worn on other parts of the body such as limbs, forearms, or upper arms. The electronic device can be used to determine the user's current location, travel distance, speed, and other performance indicators by receiving location signals from a satellite-based positioning system such as a global navigation satellite system (GNSS). In an embodiment, the wrist-worn device can receive a GNSS location signal from a satellite-based positioning system having a single frequency band. In other embodiments, in order to further improve the accuracy of position determination and related performance indicators, the electronic device can be configured to wirelessly receive GNSS signals having two separate frequency bands such as the L1 and L5 GPS bands. In addition, the electronic device can be electronically paired and communicate with other devices such as a heart rate monitor typically worn around the user's chest, a foot stand attached to the user's shoe for measuring jogging or running cadence and distance, a bicycle speed and cadence sensor attached to the crank arm or wheel hub of the user's bicycle for determining and tracking cycling performance, etc. In addition, the electronic device can be able to communicate with a smart phone, tablet, laptop or desktop computer, Wi-Fi router, cellular tower, etc. to allow the user to send (upload) location and activity data, download applications, stream (continuously download) music, receive text messages, emails and weather alerts, etc. Thus, the electronic device can receive and / or send, utilize or process location signals such as GNSS signals output by a satellite system or such as using Bluetooth. TM , Wi-Fi, or telecommunications cellular protocol signals, etc. Typically, each type of signal and (in some cases) protocol may require the use of a separate antenna within the housing or frame of the device to wirelessly send and / or receive the various signals.

[0025] When the electronic device is implemented by a wristwatch, some wearers prefer a housing and frame formed of conductive materials, which may be an annular ring surrounding the watch display. In contrast, non-conductive materials such as plastics are commonly used in the housing of conventional watches. Therefore, to make the watch more fashionable, the housing and frame may be formed of metal and / or metal alloys. For electronic devices that implement wireless communication, it is good practice to set the antenna away from the electronic circuit devices such as position determination elements, communication elements or processing elements in the watch that process electronic signals and provide other functions. Some known conventional wrist-worn devices lay or incorporate one or more antennas on the outer surface of the wall of the housing or in these walls. However, given that it may be desirable that the walls of the watch housing and frame be formed of conductive materials (metal and / or metal alloys), the one or more antennas cannot usually be laid or incorporated on or in the housing wall or frame, because it may be challenging to isolate the one or more antennas from the rest of the housing wall or frame, and the insufficient isolation of the one or more antennas may cause undesirable interference to the signals wirelessly transmitted or received by the device. Therefore, it is necessary to design and construct a device that can wirelessly receive and / or transmit electrical signals (e.g., receive multiple GNSS signals, communicate with Bluetooth TM Wrist-worn electronic devices with metal casings and frames (such as those for communicating with wireless, Wi-Fi, or cellular devices or systems) are a challenge.

[0026] The electronic device of the present technology has a housing and a frame formed of a conductive material (metal and / or metal alloy), and is configured to wirelessly receive GNSS signals and communicate with other devices or systems using multiple communication protocols. The electronic device solves the challenges discussed above by implementing certain improvements that enable the combination of a first GNSS antenna for receiving GNSS position signals in a first frequency band, a second GNSS antenna for receiving GNSS position signals in a second frequency band, and a GNSS antenna for using Bluetooth TM, Wi-Fi or cellular protocols to send and receive communication signals. Specifically, some parts of the conductive housing and the frame can be used to form one or more slot antenna components, each of which includes an upper conductor and a separated lower conductor, wherein the left conductor and the right conductor connect the upper conductor and the lower conductor. The space between the upper conductor and the lower conductor forms a slot of each antenna, wherein the width of each slot corresponds to the wavelength of the wireless signal being received and / or transmitted by the corresponding antenna. In the slot antenna, the side wall of the housing can be used as the lower conductor and the frame can be used as the upper conductor, because the electronic device also includes a housing insulation ring, which is arranged between the side wall of the housing and the lower edge of the frame and is formed of a non-conductive material such as plastic or other insulating material or filler. For a wrist-worn device having a housing in a circular shape, the housing insulation ring is in the shape of a ring. Similarly, for a wrist-worn device having a housing in a generally rectangular shape, the housing insulation ring is generally rectangular in space. Therefore, the housing insulation ring fills the space between the upper conductor and the lower conductor of the slot antenna. Two conductive connectors respectively form a left conductor and a right conductor of each slot antenna, which pass through the housing insulating ring to electrically couple (connect) the electrically grounded side wall of the housing with the frame.

[0027] Embodiments of the technology will now be described in more detail with reference to the drawings of the accompanying drawings.

The frame 60 is formed by a conductive material such as a metal and / or a metal alloy.

Using data and information from position signals output by GOS satellites on both the GPS L1 frequency band and the GPS L5 frequency band, the position determining element 22 of the present technology can determine the current geographic location of the electronic device 10 with a higher accuracy than conventional devices that can only utilize position signals output by GPS satellites on the GPS L1 frequency band alone. The position determining element 22 can transmit the determined current geographic location to the processing element 20, store the determined current geographic location in the memory element 18, or do both.

The printed circuit board connector 42 is electrically coupled to one or more partial or full signal planes and / or one or more signal traces of the printed circuit board 28 from a location proximate to the inner surface of the side wall 54 of the lower housing 12A, or provides an electrical connection from that location to one or more partial or full signal planes and / or one or more signal traces of the printed circuit board. Figure 5 , one of the printed circuit board connectors 42 is shown. Although the printed circuit board connectors 42 may be implemented by a variety of connector configurations or packages, an exemplary embodiment of the printed circuit board connector 42 includes a lower conductor, three side walls, an upper conductor that contacts the printed circuit board 28 (and is electrically coupled or electrically connected to its planes or traces), and arms that extend outwardly from the upper conductor and are electrically connected to the side wall 54.

The slot antenna structure includes an upper conductor, a lower conductor, a left conductor, and a right conductor that are connected to each other to form or produce a slot. Each slot has a height marked as "H" and a width marked as "W". Typically, for wrist-worn devices, the width of each slot is greater than the height of the slot. A signal feed electrically coupled to an electronic receiver and / or transmitter is electrically coupled to the lower edge of the upper conductor (the upper edge of the slot). When the slot antenna receives a wireless signal, the corresponding electronic signal is electrically transmitted from the signal feed point to the receiver via the printed circuit board connector 42. When the transmitter electrically transmits the electronic signal to the slot antenna, the slot antenna wirelessly transmits the corresponding signal. The width of the slot corresponds to all or part (such as half or quarter) of the wavelength of the wireless signal to be received and / or transmitted.

The left conductor of the communication antenna 48 is formed by the first bezel connector 30. The right conductor of the communication antenna 48 is formed by the sixth bezel connector 40, which is formed at Fig. 9B 48 is labeled as "G3" because it is used only as an electrical ground or common electronic signal path for the communication antenna 48 in this embodiment. Fig. 9B As shown in , the second end of the third portion of the circumference of the border 60 formed by the sixth border connector 40 is arranged to be closer (when measured along the circumference of the border 60 in a clockwise direction) to the juxtaposed first ends of the second and third portions of the circumference (located at approximately 9:00) than the second end of the second portion of the circumference of the border 60 formed by the sixth border connector 40 (because the sixth border connector 40 associated with the second end of the third portion is located at approximately 12:00 and the third border connector 34 associated with the second end of the second portion is located at approximately 3:00). The lower conductor of the communication antenna 48 is formed by the third portion of the circumference of the side wall 54 of the lower shell 12A, as shown Fig. 9B . A third portion of the circumference of the side wall 54 is arranged to be aligned with a third portion of the circumference of the bezel 60, extending generally from 9:00 to 12:00 in a clockwise direction. Thus, the third portion of the circumference of the side wall 54 associated with the communication antenna 48 partially overlaps with the second portion of the circumference associated with the second GNSS antenna 46, which is arranged within the second end of the second portion of the circumference. The communication antenna 48 is electrically coupled to the communication element 24 via the fifth bezel connector 38, one of the printed circuit board connectors 42, and the signal traces of the printed circuit board 28, and the fifth bezel connector is arranged at Fig. 9BThe second end of the third portion of the bezel 60 is electrically coupled or electrically connected to the antenna tuning network 26 on the printed circuit board 28. The antenna tuning network 26 is configured to cause signals having one or more frequencies to be received using the communication antenna 48 to pass through the sixth bezel connector 40. The communication antenna 48 is electrically coupled to the sixth bezel connector 40 and is configured to cause frequency components of the communication electronic signal within a selected frequency band to pass from the bezel 60 through the sixth bezel connector 40, thereby causing the length of the signal path associated with the communication antenna 48 to be shorter than the signal path associated with the second GNSS antenna 46. The communication antenna 48 is electrically coupled to the communication element 24 (including its receiver and transmitter) via the fifth bezel connector 38, one of the printed circuit board connectors 42, and a signal trace. The fifth bezel connector is electrically coupled to the communication element 24 at Fig. 9B It is labeled as “F2, F3” in FIG. 4 (because it serves as the feed point for the second GNSS antenna 46 and the communication antenna 48).

[0047] exist Figure 1 In the embodiment of electronic device 10 shown in FIG. 1 , the upper conductors of first GNSS antenna 44, second GNSS antenna 46, and communication antenna 48 each occupy some portion (some partially overlapping) of the circumference of bezel 60 as shown. The remaining portion of the circumference of bezel 60 not associated with the antennas may be electrically connected to electrical ground.

[0048] The first GNSS antenna 44 and the second GNSS antenna 46 may each be configured to receive any one of the GNSS constellation wireless signals. However, in an exemplary embodiment, the first GNSS antenna 44 is configured to receive GPS L1 band wireless signals having a center frequency of approximately 1575 MHz, thereby outputting or delivering a first position electronic signal to the position determining element 22 via the printed circuit board connector 42. The second GNSS antenna 46 is configured to receive GPS L5 band wireless signals having a center frequency of approximately 1175 MHz, thereby outputting or delivering a second position electronic signal to the position determining element 22.

[0049] The communication antenna 48 receives or transmits a signal such as Bluetooth having a center frequency of approximately 2.4 GHz. TM or Wi-Fi. The communication antenna 48 then outputs or transmits the communication electronic signal to or from the communication element 24 when necessary. Therefore, when the electronic device 10 needs to communicate via LTE, Bluetooth TM When sending data via Wi-Fi or Wi-Fi, the communication element 24 outputs the communication electronic signal (including data) to the communication antenna 48, which in turn sends the communication wireless signal.

The electronic device 100 includes all components of the electronic device 10, except that the second GNSS antenna 46 is combined with the long-term evolution (LTE) antenna to form a supplementary GNSS and LTE antenna 164. The electronic device 100 also includes the second communication element 166. When Bluetooth TM When cellular and Wi-Fi are not available, the electronic device 100 can be utilized to provide cellular access for telecommunications such as voice calls and other communications such as text messaging and Internet access.

[0051] The second communication element 166 processes the second communication electronic signal that allows the electronic device 10 to communicate with a cellular (telecommunication) system, network, router, switch, etc. The second communication element 166 includes components similar to those of the (first) communication element 24, which allow the second communication element 166 to process a second communication electronic signal with an operating frequency in the range of approximately 600MHz to approximately 900MHz, which includes low-band LTE or similar telecommunication protocols. The second communication element 166 can decode the data received in the second communication electronic signal and encode the data in the second communication electronic signal to be sent. The second communication electronic signal is transmitted between the second communication element 166 and the supplementary GNSS and LTE antenna 164.

[0052] In various embodiments, the components and functionality of the second communication element 166 may be included in the (first) communication element 24 , and thus, the second communication electronic signals may be transmitted between the (first) communication element 24 and the supplemental GNSS and LTE antenna 164 .

[0053] The supplemental GNSS and LTE antenna 164 is typically implemented as a slot antenna, although other implementations are possible. Assuming that the ranges of operating frequencies of the L5 GPS band and the low band of LTE are not too far from each other, the width of the slot of the second GNSS antenna can be expanded a small amount to form the supplemental GNSS and LTE antenna 164, so that the supplemental GNSS and LTE antenna 164 is operable in both the L5 GPS band and the low band of LTE.

[0054] Reference Fig. 12A and Fig. 12B The slot antenna structure components of the supplementary GNSS and LTE antenna 164 are formed by the following components of the electronic device 100.

Fig. 12B , the fourth portion is arranged to be aligned with a fourth portion of the circumference of the bezel 60, extending in a clockwise (CW) direction from approximately 9:00 to approximately 4:00. The supplemental GNSS and LTE antenna 164 is electrically coupled to both the position determination element 22 and the second communication element 166 via the fifth bezel connector 38, one of the printed circuit board connectors 42, and the signal traces of the printed circuit board 28. The fifth bezel connector is connected to the PCB 28 at the bottom of the bezel 60. Fig. 12B It is labeled “F2, F3, F4” in the figure (because it serves as the feed point for the communication antenna 48 and the supplementary GNSS and LTE antenna 164).

[0055] The supplemental GNSS and LTE antenna 164 is configured to receive GPS L5 band wireless signals having a center frequency of approximately 1175 MHz, and then output or transmit the second position electronic signal to the position determination element 22. The supplemental GNSS and LTE antenna 164 is also configured to receive a second communication wireless signal in the low frequency band of LTE, which has a frequency range from approximately 600 MHz to approximately 900 MHz. The supplemental GNSS and LTE antenna 164 then outputs or transmits the second communication electronic signal to the second communication element 166. When the electronic device 100 needs to send data via the cellular LTE network, the supplemental GNSS and LTE antenna 164 outputs the second communication electronic signal (including data) to the supplemental GNSS and LTE antenna 164, and the supplemental GNSS and LTE antenna then wirelessly transmits the communication signal.
