[0039] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0040] It should be noted that the user-related information and data involved in the embodiments of this specification are all information and data authorized by the user or fully authorized by relevant parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with relevant laws, regulations and standards, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users or relevant parties to choose to authorize or refuse.

[0041] It should also be noted that in the embodiments of this specification, certain software, components, models and other existing solutions in the industry may be mentioned, which should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0042] Considering that in order to enable users to view rich and diverse data information through the watch when they need it, and support users to perform various complex operations; at the same time, it is necessary to meet the energy-saving needs of users and extend the overall standby time of the watch. It can be considered to introduce the first display screen and the second display screen at the same time in the dial body of the watch; wherein the first display screen is located above the second display screen, and the first display screen is a color display screen, the second display screen is a monochrome display screen, and the first display screen is a transparent display screen. Then the above-mentioned first display screen and the second display screen are combined with the circuit main board, specifically from top to bottom in the order of the first display screen, then the second display screen, and finally the circuit main board to obtain the dial body of the watch. In this way, the user can switch to use the first display screen and the second display screen of the watch more freely. When needed, the first display screen can be put in the display state, and the first display screen can be used for the main display and operation; when not needed, the first display screen can be turned off, so that the first display screen presents the form of transparent glass, and then the first display screen can be used to display basic data information through the second display screen, so that while meeting the diverse use needs of users, the overall energy consumption of the watch can be effectively reduced and the standby time of the watch can be extended.

[0043] Furthermore, considering that the watch based on the above structure has gaps between the first display screen and the second display screen, and between the second display screen and the circuit main board, that is, the first gap and the second gap. In order to avoid further increasing the volume and weight of the watch, the watch is made as small and light as possible; at the same time, in order to make the watch have relatively better wireless communication performance, the user experience when using the watch for wireless communication is improved. Consider that a first transparent antenna adapted to the wireless communication signal of the watch can be made of a transparent conductive material, and a first transparent auxiliary structure matched with the first transparent antenna can be made of a transparent material; and then the first transparent antenna and the first transparent auxiliary structure are respectively arranged in the second gap and the first gap. In this way, the existing space structure between the first display screen, the second display screen, and the circuit main board in the watch can be fully utilized. Under the premise of not increasing the volume and weight of the watch and not affecting the use and appearance of the watch, by introducing and combining the first transparent antenna and the first transparent auxiliary structure, the quality of wireless communication of the watch can be effectively improved, so that the user can get a better use experience.

[0044] Based on the above considerations, see Figure 1As shown, the embodiment of this specification provides a wireless communication watch, which may at least include: a first display screen, a second display screen, and a circuit main board;

[0045] A first transparent auxiliary structure is arranged in a first gap between the first display screen and the second display screen;

[0046] A first transparent antenna is arranged in the second gap between the second display screen and the circuit main board; wherein the first transparent antenna is electrically connected to the circuit main board through a flexible feeder; and the first transparent antenna is used to receive and send wireless communication signals;

[0047] The first display screen is a color display screen, and the second display screen is a monochrome display screen.

[0048] For details, please refer to Figure 1 As shown, in the wireless communication watch, the first display screen, the second display screen and the circuit main board arranged in sequence from top to bottom constitute the dial body of the wireless communication watch.

[0049] The dial body can be nested in the watch case to protect the dial body through the watch case. Furthermore, a transparent protective layer can be provided on the surface of the first display screen away from the second display screen, that is, on the upper surface of the first display screen. Specifically, the transparent protective layer can be a glass layer.

[0050] In addition, corresponding watch straps can be connected to both sides of the watch housing, so that the user can wear the wireless communication watch on the wrist conveniently.

[0051] Specifically, the first display screen and the second display screen can be electrically connected to the circuit main board through a transparent feeder line. The first display screen can be a color display screen, and the second display screen can be a monochrome display screen.

[0052] The first display screen can display information data with rich colors and complex forms (including text, pictures, videos, etc.), support users' diverse operations, and meet users' diverse usage needs, but the power consumption during operation is relatively large. The second display screen can display information data with a single color and simple form, such as time, date, etc., to meet basic needs, but the power consumption during operation is relatively small.

[0053] Furthermore, the first display screen may be a transparent display screen, such as an OLED transparent screen, an LED transparent screen, an LCD transparent screen, etc. When the transparent display screen is in a display state, it appears as an opaque display screen and displays normally; when it is in a non-display state, it appears as transparent glass.

[0054] In specific implementation, when the user needs to use the display screen of the wireless communication watch to perform more delicate and complex operations, a first trigger instruction can be initiated. Correspondingly, the circuit main board receives and responds to the above-mentioned first trigger instruction, and wakes up the first display screen through the transparent feeder to put it in a display state. At this time, the first display screen becomes an opacity display screen, covering the second display screen; at the same time, the corresponding interface and information are normally displayed to the user to support the user to perform more delicate and complex operations.

[0055] When the user does not need to use the display screen of the wireless communication watch for more delicate and complex operations, a second trigger instruction can be initiated. Accordingly, the circuit main board receives and responds to the second trigger instruction, and turns off the first display screen through the transparent feeder to put it in a non-display state. At this time, the first display screen becomes transparent glass, and the user can observe the basic information such as time and date displayed by the second display screen in monochrome with lower power through the first display screen in this state.

[0056] Specifically, a first transparent auxiliary structure may be provided in the first gap between the first display screen and the second display screen; meanwhile, a first transparent antenna may be provided in the second gap between the second display screen and the circuit main board; wherein the first transparent antenna matches the first transparent auxiliary structure.

[0057] Among them, the above-mentioned first transparent antenna can be designed and manufactured according to the wireless communication signal of the watch.

[0058] In specific implementation, the first transparent antenna can be used to receive and send wireless communication signals of the watch without changing the appearance of the watch or affecting the user's use of the watch, so that the user can use the watch for wireless communication.

[0059] At the same time, by utilizing the first transparent auxiliary structure, the first transparent antenna can be assisted to better realize wireless communication without changing the appearance of the watch or affecting the user's use of the watch, so that the user can have a better user experience.

[0060] The wireless communication watch may be a smart watch supporting wireless communication or a non-smart watch supporting wireless communication.

[0061] In some cases, specifically, the first transparent auxiliary structure and the first transparent antenna can be arranged in the first gap. The first transparent auxiliary structure can be arranged on the lower surface of the first display screen in the first gap, and the first transparent antenna can be arranged on the upper surface of the second display screen in the first gap.

[0062] Based on the wireless communication watch with the above structure, the user can switch to the first display screen that consumes more power and displays clearer and richer images when needed, and can switch to the second display screen that consumes less power and is eye-protecting and energy-saving when not needed, thereby meeting the user's diverse scenario needs and effectively reducing the energy consumption of the watch; further, by making full use of the space structure between the first display screen and the second display screen in the watch, a matching first transparent antenna and a first transparent auxiliary structure are set at the corresponding gap position, without increasing the size and weight of the watch and without affecting the use of the watch, the wireless communication quality of the watch can be effectively improved, the standby time of the watch can be increased, and the user can have a better user experience.

[0063] In some embodiments, the first transparent auxiliary structure may specifically include a transparent supersurface structure; wherein the transparent supersurface structure includes a plurality of periodically arranged transparent conductive unit patterns, and the transparent supersurface structure is used to assist in improving the gain of the first transparent antenna.

[0064] The above-mentioned metasurface can be specifically understood as a layered structure with a thickness less than the wavelength, based on which the polarization, amplitude, phase, polarization mode, propagation mode and other characteristics of the wireless communication signal of the watch (i.e., the wireless communication signal received and sent by the first transparent antenna) of the electromagnetic wave can be effectively regulated. The above-mentioned transparent metasurface structure can specifically be a metasurface made of transparent conductive material.

[0065] For details, please refer to Figure 2 As shown, each of the above transparent conductive unit patterns can be a pattern made of corresponding transparent conductive materials with a narrower side width. In this way, the shielding and influence of the transparent conductive pattern group arranged between the glass layers on the light can be effectively reduced, so that the multi-layer glass assembly as a whole still has good light transmittance.

[0066] Furthermore, the transparent conductive unit pattern is a sub-wavelength unit pattern whose size parameter is smaller than the wavelength of the wireless communication signal of the watch. Accordingly, the multiple transparent conductive unit patterns can be arranged periodically to form a transparent metasurface adapted to the wireless communication signal of the watch. Based on the transparent metasurface, the gain of the first transparent antenna can be improved by enhancing the wireless communication signal of the watch.

[0067] In a specific implementation, the size parameters of the transparent conductive unit pattern can be set to be greater than or equal to 0.1 times the working wavelength of the wireless communication signal of the watch, and less than or equal to 0.4 times the working wavelength. Based on the above size parameters, the constructed transparent metasurface can have a good gain effect on the wireless communication signal of the watch.

[0068] In some embodiments, the transparent conductive unit pattern is a unit pattern with a size parameter smaller than the wavelength of the wireless communication signal of the watch and a central symmetry.

[0069] Specifically, the pattern shape of the transparent conductive unit pattern may include at least one of the following: a circular ring, a square ring, a triangular ring, a regular hexagonal ring, an elliptical ring, and the like.

[0070] The above pattern shape satisfies the central symmetry on the one hand, and matches the wireless communication signal of commonly used watches on the other hand, and has good applicability.

[0071] In specific implementation, the shape that matches the frequency of the wireless communication signal of the watch can be determined as the shape of the transparent conductive unit pattern. The size parameters of the transparent conductive unit pattern can then be accurately determined based on the wavelength (or frequency) of the wireless communication signal of the watch, the thickness of the glass layer, the gap thickness, and the incident angle and polarization mode of the wireless communication signal of the watch.

[0072] Specifically, according to the wavelength of the wireless communication signal of the watch, it can be determined that the maximum size of the transparent conductive unit pattern is greater than or equal to 0.1 times the working wavelength of the wireless communication signal of the watch, and less than or equal to 0.4 times the working wavelength of the wireless communication signal of the watch.

[0073] Specifically, according to the wavelength of the wireless communication signal of the watch, it can be determined that the annular line width of the transparent conductive unit pattern is greater than 60um, so that the formed transparent metasurface structure can obtain a better gain effect when acting on the wireless communication signal of the watch.

[0074] In some embodiments, the first transparent auxiliary structure may specifically include a transparent electromagnetic bandgap structure; wherein the transparent electromagnetic bandgap structure is used to assist the first transparent antenna in unidirectional radiation.

[0075] The above-mentioned electromagnetic band gap (EBG) can be specifically understood as a special artificial electromagnetic material layer, which has the characteristics of a high impedance surface, can suppress the harmonic radiation of the antenna, and reduce the interference to the surrounding microwave devices. The above-mentioned transparent electromagnetic band gap structure can be specifically an electromagnetic band gap made of transparent conductive material.

[0076] Based on the above-mentioned transparent electromagnetic bandgap structure, on the one hand, it will not affect the aesthetics of the watch, nor will it block the first display screen and the second display screen; on the other hand, it can suppress the harmonic radiation of the first transparent antenna and assist the first transparent antenna to perform unidirectional radiation to avoid affecting and interfering with other surrounding equipment and devices, thereby further improving the user experience.

[0077] In some embodiments, the first transparent auxiliary structure may further include a second transparent antenna; wherein the second transparent antenna is used to assist in increasing the communication bandwidth of the first transparent antenna.

[0078] Among them, the frequency band of the wireless communication signal of the watch adapted by the second transparent antenna is different from or not completely the same as the frequency band of the wireless communication signal of the watch adapted by the first transparent antenna.

[0079] This is because the bandwidth of the first transparent antenna is limited. Based on the first transparent antenna, in most cases it can only adapt to the frequency band of the main working signal of the watch's wireless communication signal (for example, 5G signals, 4G signals and other mobile communication signals, frequency band: 1.4GHz-6.4GHz). The adaptability to working signals in other frequency bands (for example, GPS signals, Bluetooth signals, WLAN signals, etc.) is relatively poor, resulting in the overall narrow communication bandwidth of the watch, which cannot fully and accurately cover working signals of multiple frequency bands, affecting the user experience when using working signals in frequency bands other than the main working signal for wireless communication.

[0080] Based on the above structure, a second transparent antenna adapted to working signals in other frequency bands can be introduced and used as the first transparent auxiliary structure. Without affecting the appearance of the watch and the normal use of the watch, it can serve as a supplement to the first transparent antenna to fully cover working signals in multiple frequency bands, thereby assisting in increasing the communication bandwidth of the first transparent antenna.

[0081] In some embodiments, the first transparent antenna may specifically match a mobile communication signal, and the second transparent antenna may specifically match a GPS signal (frequency band: 1.57 GHz).

[0082] In this way, the wireless communication watch can, on the one hand, better realize wireless communication based on mobile communication signals to meet the user's needs of using the watch for mobile communication; on the other hand, it can also better realize wireless communication based on GPS signals to meet the user's needs of using the watch for satellite positioning.

[0083] In addition, the second transparent antenna can be electrically connected to the circuit main board through a flexible feeder.

[0084] In some embodiments, the second transparent antenna may specifically include a first sub-antenna disposed on one side of the lower surface of the first display screen and a second sub-antenna disposed on one side of the upper surface of the second display screen;

[0085] The first sub-antenna matches the GPS signal, and the second sub-antenna matches the WLAN signal (frequency band: 2.4 GHz, 5 GHz).

[0086] Accordingly, the first sub-antenna can be used to better implement wireless communication based on GPS signals; meanwhile, the second sub-antenna can be used to better implement wireless communication based on WLAN signals (for example, WIFI communication, etc.).

[0087] The lower surface of the first display screen may specifically refer to the surface of the first display screen that is closer to the second display screen among the two surfaces of the first display screen. The upper surface of the second display screen may specifically refer to the surface of the second display screen that is closer to the first display screen among the two surfaces of the second display screen.

[0088] During specific implementation, the first sub-antenna and the second sub-antenna may also be arranged at different positions on the same surface as the first display screen or the second display screen.

[0089] For example, the first sub-antenna may be disposed in a left area of ​​the upper surface of the first display screen; and at the same time, the second sub-antenna may be disposed in a right area of ​​the upper surface of the first display screen.

[0090] Specifically, considering that the frequency band of the WLAN signal is relatively close to the frequency band of the Bluetooth signal, the second sub-antenna can also be used to better implement wireless communication based on the Bluetooth signal.

[0091] Based on the above embodiment, the second transparent antenna can be used as the first transparent auxiliary structure to realize wireless communication of working signals in other frequency bands except mobile communication signals, thereby meeting relatively diverse communication needs of users.

[0092] In some embodiments, the first transparent auxiliary structure may specifically include a combination of at least two of the following: a transparent metasurface structure, an obvious electromagnetic bandgap structure, and a second transparent antenna.

[0093] Furthermore, the first transparent auxiliary structure can be used to assist the operation of the first transparent antenna from multiple dimensions, so that the user can obtain a relatively better user experience when using the watch.

[0094] In some embodiments, a second transparent auxiliary structure is further disposed on a surface side of the circuit main board away from the second display screen.

[0095] Specifically, for example, a second transparent auxiliary structure may be provided on the lower surface of the circuit mainboard, wherein the second transparent auxiliary structure may specifically include at least one of the following: a transparent metasurface structure, an obvious electromagnetic bandgap structure, and a second transparent antenna.

[0096] Based on the above watch, the first transparent auxiliary structure and the second transparent auxiliary structure arranged at different positions can be used in combination to more effectively and comprehensively assist the first transparent antenna in wireless communication, so that users can get a better user experience.

[0097] In some embodiments, the shape of the first transparent antenna may specifically include at least one of the following: rectangle, square, rhombus, triangle, polygon, circle, ellipse, fractal structure, etc.;

[0098] In addition, the structure of the first transparent antenna includes: a single-layer structure or a multi-layer structure, etc.

[0099] During specific implementation, a matching shape can be determined as the shape of the first transparent antenna according to the frequency of the main working signal of the wireless communication signal of the watch.

[0100] Specifically, for example, the basic antenna shape can be determined based on the frequency of the main working signal of the wireless communication signal of the watch; then, combined with the material properties of the transparent antenna, the thickness of the display screen, the gap thickness and other related parameters, the basic antenna shape is simulated and simulated, and multiple iterations are performed to determine the fractal structure that meets the requirements at the frequency of the main working signal of the wireless communication signal of the watch, and the first transparent antenna is made as the final matching shape. For details, please refer to Figure 3 , Figure 4 , Figure 5 The determination process shown.

[0101] This can make the frequency band of the first transparent antenna relatively wider, and provide better receiving and sending performance for the wireless communication signal of the watch; at the same time, it also makes the antenna relatively more compact, making the watch as a whole relatively lighter.

[0102] Specifically, the specific size of the first transparent antenna can be designed in combination with the surface area of ​​the display screen, so that the first transparent antenna does not exceed the surface of the display screen.

[0103] According to the type, a second transparent antenna that meets the requirements can be manufactured. This specification does not elaborate on this.

[0104] In some embodiments, the first transparent antenna may be made of a transparent conductive material and a transparent flexible medium.

[0105] The transparent conductive material may specifically include: at least one of the following: transparent oxides such as ITO and FTO, and / or AgHT, graphene, carbon nanotubes, silver nanowires, metal (silver, copper, etc.) grids, etc.

[0106] Among them, the above-mentioned ITO, FTO and AgHT refer to indium tin oxide, fluorine-doped tin oxide and silver tin oxide respectively.

[0107] The transparent flexible medium includes at least one of the following materials: PET, PDMS, PI and the like.

[0108] The above-mentioned PET, PDMS and PI refer to polyethylene terephthalate, polydimethylsiloxane and polyimide respectively.

[0109] The above-mentioned flexible feeder can be made of FPC flexible material, wherein FPC specifically refers to a flexible printed circuit board.

[0110] In some embodiments, the transparent antenna (including: the first transparent antenna and the second transparent antenna) can be etched onto the surface of the corresponding display screen.

[0111] The transparent antenna can also be pasted onto the surface of a corresponding display screen to reduce damage to the display screen.

[0112] Specifically, a corresponding transparent antenna may be firstly manufactured on a transparent conductive film coating (eg, a single-layer ITO film); and then the transparent antenna may be adhered to the surface of a corresponding display screen using a transparent optical adhesive.

[0113] In some embodiments, the second gap may specifically be a transparent resin gap.

[0114] Here, a transparent resin gap is used as the second gap. On the one hand, the physical properties of the resin can be used to physically protect the transparent antenna set in the second gap to prevent the transparent antenna from being broken and damaged due to collision, which would affect the wireless communication performance of the watch. On the other hand, since the resin itself is transparent, it will not affect the user's normal observation of the data information displayed on the second display screen through the resin gap.

[0115] In some embodiments, the first gap may specifically be an air gap.

[0116] Specifically, the first gap and the second gap may be gaps made of the same material or gaps made of different materials. In specific implementation, gaps made of appropriate materials may be selected as the first gap and the second gap according to specific application scenarios and processing requirements.

[0117] In some embodiments, during specific implementation, in addition to the first transparent antenna set in the second gap, transparent antennas based on corresponding radiation directions and polarization modes can be set on one or more of the upper surface of the first display screen, the lower surface of the first display screen, the upper surface of the second display screen, the lower surface of the circuit main board and other position areas, respectively. The above-mentioned transparent antenna can be combined with the first transparent antenna to form a directional pattern diversity and polarization diversity that meet the requirements to meet the needs of diverse communication scenarios.

[0118] In some embodiments, a light sensor may be provided at a designated position of the first display screen, wherein the light sensor is electrically connected to the circuit board via a flexible feeder, and the designated position may be the upper left corner of the first display screen.

[0119] In specific implementation, when the user wants to switch to use the display screen, he can make corresponding operation gestures facing the light sensor according to the instructions. The light sensor can sense and receive the light change data generated by the user's operation gesture; and send the above light change data to the circuit main board through the flexible feeder. The circuit main board can identify the command based on the above light change data, determine whether it is a trigger command, and whether it is the first trigger command or the second trigger command. Then, when it is determined to be a trigger command, it can respond to the trigger command and accurately and automatically complete the switching of the display screen.

[0120] During specific implementation, after starting the first display screen and making the first display screen in a display state, the light sensor can also continuously collect light change data and send it to the circuit main board. The circuit main board can determine whether the user is watching and using the first display screen based on the above light change data. When the circuit main board detects that the user has not watched or used the first display screen for a continuous preset waiting time (for example, 5 minutes), it can be determined that the user no longer needs to use the first display screen. At this time, the circuit main board can automatically turn off the first display screen through a flexible feeder, so that the first display screen is in a non-display state. In this case, the basic data information can be displayed through the first display screen using the second display screen with lower energy consumption. Thereby, energy consumption can be further reduced and the standby time of the watch can be increased.

[0130] It should be noted that the units, devices or modules described in the above embodiments can be implemented by computer chips or entities, or by products with certain functions. For the convenience of description, the above devices are described separately by functions divided into various modules. Of course, when implementing this specification, the functions of each module can be implemented in the same or more software and / or hardware, or the modules that implement the same function can be implemented by a combination of multiple sub-modules or sub-units. The device embodiments described above are only schematic. For example, the division of the units is only a logical function division. There may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, indirect coupling or communication connection of devices or units, which can be electrical, mechanical or other forms.

[0131] In a specific scenario example, a wireless communication watch provided in this specification can be used to design a transparent antenna device for a dual-display smart watch. For the specific implementation process, please refer to the following content.

[0132] In this scenario example, considering that wireless communication technology requires broadband or multi-band and compact and miniaturized single-plane antennas to support wireless devices. Therefore, in modern multi-standard wireless communication systems, compact planar antennas with broadband or multi-band working capabilities, small size, low cost, and flexibility are a direction worthy of attention. Furthermore, the above-mentioned compact planar antenna can be placed in wearable electronic devices as a wearable antenna to meet the needs of the Internet of Things and smart life.

[0133] Considering that optically transparent electronic devices are becoming more and more popular due to the development of new materials and transparent technologies, transparent antennas have attracted great attention in the wide application of optically transparent devices due to their easy integration and more beautiful appearance when placed on the surface of objects. It is achieved by integrating transparent conductive materials with transparent dielectric substrates and has a wide range of applications in various fields, including wearable technology, flexible electronics, solar panels, glasses, and emerging technologies.

[0134] There are many technologies that combine active and passive components on flexible substrates to reduce size and weight for communication with wearable electronic devices, and the demand for flexible antennas is expanding. For wireless devices, flexible antennas are compact, flexible, reconfigurable, and durable. Such wearable antennas are helpful for daily communications such as navigation, tracking, and remote computing. However, transparent antennas made of transparent conductive oxides are prone to breakage. To address this problem, transparent flexible antennas made of a variety of flexible materials are considered.

[0135] Based on the above considerations, the applicant proposes a transparent antenna device for smart watches using a wireless communication watch provided in this specification. Figure 1 As shown, the smart watch includes a watch case, a circuit main board, a first display screen and a second display screen. The circuit main board is located at the bottom of the inner side of the watch case, the first display screen is located above the circuit main board, and the second display screen is located above the first display screen. The transparent antenna (for example, the first transparent antenna) can be integrated at one or more of the outer side of the back of the watch case, the upper surface of the first display screen, the upper surface of the second display screen or the lower surface, for transmitting and receiving wireless signals, and the transparent antenna is connected to the RF transceiver module on the circuit main board through a flexible feeder.

[0136] The smart watch may have one or two display screens. If there are two display screens, there is an air gap between the two display screens. If the smart watch has one display screen, the transparent antenna may be integrated on the upper surface or the lower surface of the display screen; if the smart watch has two display screens, the transparent antenna may be integrated on the upper surface of the first display screen, the upper surface of the second display screen, or the lower surface.

[0137] Specifically, the transparent antenna is composed of a transparent conductive material and a transparent flexible medium. The transparent antenna is adhered to the surface of the display screen by optical adhesive, or it can be directly etched on the surface of the display screen, or it can be integrated on the outer side of the back of the watch case.

[0138] The conductor part of the transparent antenna is made of transparent conductive materials, including but not limited to transparent oxides such as ITO and FTO, AgHT, graphene, carbon nanotubes, silver nanowires, metal (silver, copper, etc.) grids, etc. The above transparent conductive materials can be pasted or directly etched on the watch case and display surface. If pasting is used, the transparent conductive material needs to be attached to a transparent flexible medium, which includes but is not limited to PET, PDMS, PI and other materials.

[0139] Specifically, the transparent antenna may be in the shape of a rectangle, square, rhombus, triangle, polygon, circle, ellipse, fractal structure, etc., and the antenna may be a single-layer or multi-layer structure.

[0140] Preferably, the antenna can be integrated into one or more of the outer side of the back of the watch case, the upper surface of the first display screen, the upper surface of the second display screen or the lower surface. If the antenna is deployed at one of the above surfaces, the other surfaces can be deployed with metasurfaces, electromagnetic band gaps and other structures (for example, a first transparent auxiliary structure) to enhance antenna radiation; if the antenna is deployed at multiple locations on the above surfaces, a multi-antenna structure can be formed.

[0141] Specifically, the transparent antenna can be fed through an FPC flexible circuit, and the flexible circuit connects the transparent antenna feeding port and the RF transceiver module on the circuit board. The overall lateral size of the transparent antenna and its feeder does not exceed the lateral size of the dial.

[0142] In specific implementation, the transparent antenna can use a single layer of ITO film as the conductive material of the antenna, the thickness is negligible, and the surface resistance is 3Ω / sq. The dielectric substrate is a PET film with a thickness of 0.125mm and a relative dielectric constant of 3. It can be made using the technology of etching on ITO / PET film. The antenna covers the GPS frequency band (1.57GHz) and the WLAN frequency band (2.4GHz, 5GHz), meeting the needs of smart watch positioning and wireless communication.

[0143] Specifically, the radiator shape of the antenna is an equilateral triangle (eg, a basic antenna shape) through a Figure 3 (Transparent antenna radiator hexagonal generation process diagram) as shown in the transformation, and then as follows Figure 4 The first iteration of the Koch curve shown in (Basic figure of transparent antenna radiator) obtains the hexagonal basic figure, and then passes through Figure 5 The antenna ground uses defect ground technology to deepen the reflection coefficient. The final antenna plane structure (for example, fractal structure) is shown in Figure 1. Figure 6 shown.

[0144] In the specific implementation, the antenna can be attached to the cover of the smart watch by optical adhesive, and a silicon aluminum glass simulated glass cover with a thickness of 1.3 mm is defined, and its relative dielectric constant is 7.882. The side view of the effect of attaching the antenna to the glass is as follows: Figure 7 The specific size parameters and meanings of the designed antenna (eg, the first transparent antenna) can be found in Table 1.

[0147] In specific implementation, the performance indicators of the smart watch antenna can be simulated and analyzed using CST 3D electromagnetic simulation software. The specific simulation analysis results are as follows:

[0148] See also Figure 8 As shown, it is a curve diagram of simulated reflection coefficient of the transparent antenna applied to the smart watch, and the working frequency band below -10dB is 1.4GHz-6.4GHz.

[0149] See also Fig. 9 As shown, the far-field two-dimensional radiation pattern result of the transparent antenna applied to the smart watch in the GPS frequency band (1.57GHz) is omnidirectional radiation.

[0150] See also Fig.10 As shown, the far-field two-dimensional radiation pattern result of the transparent antenna ° applied to the smart watch in the WLAN frequency band (2.4GHz) is omnidirectional radiation.

[0151] See also Fig.11 As shown, the far-field two-dimensional radiation pattern result of the transparent antenna applied to the smart watch in the WLAN frequency band (5GHz) is omnidirectional radiation.

[0152] The efficiency data of the transparent antenna used in the smart watch at three frequency points, namely, the GPS frequency band (1.57 GHz) and the WLAN frequency band (2.4 GHz, 5 GHz), can be specifically referred to in Table 2.

[0153] Table 2

[0154] frequency 1.57GHz 2.4GHz 5GHz efficiency 11.2％ 34.4％ 20.4％

[0155] For further information, see Fig.12 As shown, the transparent antenna applied to the smart watch affects the human body at three frequencies: GPS band (1.57GHz) and WLAN band (2.4GHz, 5GHz). The SAR value of the human body is simulated, and the 10g average values ​​are 0.971W / Kg, 1.75W / Kg, and 0.438W / Kg, respectively. Fig.12 (a), (b), and (c) show the simulation results of 10g human tissue SAR values ​​(specific absorption rate) of the transparent antenna at three frequency points: GPS band (1.57GHz) and WLAN band (2.4GHz, 5GHz).

[0156] Through the above scenario examples, it is verified that a wireless communication watch provided by this specification has a wider bandwidth and optical transparency compared to the existing technology. The transparent antenna applied to the smart watch has the technical effects of wider bandwidth and optical transparency. The transparent antenna can be integrated into the display screen and shell surface, which account for the largest area of ​​the smart watch, to achieve high-efficiency wireless transmission while ensuring that the smart watch is thin and beautiful. In addition, the working frequency band of the antenna is 1.4GHz-6.4GHz, covering the GPS band (1.57GHz) and WLAN band (2.4GHz, 5GHz), meeting the needs of smart watch positioning and wireless communication.
