[0001] Priority claim

[0002] This application claims the benefit of U.S. patent application serial number 17 / 820,719, filed on August 18, 2022, the entire contents of which are incorporated herein by reference. Background Art

[0003] Integrating cellular technology into modern consumer electronic devices is a complex engineering problem. For cellular-enabled devices, the core RF technology is complex, and regulatory compliance and certification requirements are increased because these devices operate on licensed and strictly monitored spectrum. Specifically, on the antenna side, modern cellular communication standards require antenna architectures with multiple elements, each of which must be electrically isolated from each other to ensure that there is little correlation between different antenna elements. These antenna elements should be able to operate simultaneously with high radiation efficiency over wide and widely spaced frequency bands. Given the desire to maximize cellular coverage through carrier networks, some of these frequency bands are located where the wavelength is much larger than that of a typical modern smartphone itself. Essentially, the core engineering challenge of incorporating cellular technology into consumer electronic devices is the ability to design multiple electrically small antennas that are efficient and electrically isolated from each other.

[0004] Modern smartphones and tablets address these issues by dedicating large volumes to multiple antennas that are located on opposite ends of the device. Such handheld devices also rely very heavily on active tuning methods. However, wearable devices have much stricter space, weight, and battery requirements than larger devices such as modern smartphones and tablets. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The subject matter disclosed herein relates generally to eye-wear devices, and more specifically to eye-wear devices with electronics that support cellular communications with onboard electronics such as multiple antennas and cellular transceivers. Thus, the eye-wear device may include an antenna system. For example, such an antenna system may be carried by a frame, a leg, or a combination of a leg and a frame. The contemplated antenna system may include two or more loop antennas, two or more non-loop antennas (e.g., monopole antennas or dipole antennas), and / or a combination of loop antennas and non-loop antennas. According to one example, the disclosed antenna system may include a common transceiver configured for cellular communications, and the antenna is connected to the transceiver and is configured to receive (and one or more antennas may transmit) a common cellular signal.

[0024] The present application discloses a loop antenna including a loop electrical conductor. Various non-loop antenna structures (sometimes referred to as electrical or E-type antennas) are also contemplated, including loaded monopole conductors (e.g., inverted F antennas, inverted L antennas, etc.), dipole conductors, etc. As used herein, the term non-loop conductor / antenna (sometimes referred to herein as an incomplete loop antenna) refers to a dipole conductor / antenna and / or a monopole conductor / antenna, and does not include a loop antenna / conductor. In addition, the disclosed antenna elements provided by the corresponding loop and non-loop conductors will be understood to provide an actively driven antenna element, which will be distinguished from a passive ground plane element such as provided by a printed circuit board (PCB) ground plane or an extension thereof in some cases.

[0025] The antenna system may also include an electronic device configured to provide frequency domain discrimination. However, it is expected that the disclosed one or more loop antennas and / or one or more non-loop antennas may be configured (e.g., sized and shaped) for cellular communications (operation). Thus, the antenna may be configured to receive and / or transmit data in an approved frequency range (typically between 699 MHz and 2200 MHz) for communications such as 3G, 4G, 5G, 6G, and the like, and may be configured to cover even wider frequencies if desired. Specific cellular frequency bands supported may include n12, n13, n5, n8, n1, n2, n3, n66, and the like.

[0026] It should be appreciated that the antenna systems disclosed herein provide improved cellular signal reception, improved radiation efficiency, improved polarization diversity, and other benefits when compared to existing antenna systems for handheld or wearable devices.

[0027] Cellular-enabled handheld devices (mobile phones, tablets, etc.) and other cellular-enabled devices such as drones, home internet devices, hotspots, etc. do not face the space and radiation issues of wearable devices. Although smart watches support cellular, they usually process very little cellular data. Wearable devices with AR capabilities, such as the electronic eye-wear devices with cellular functions disclosed in this article (sometimes referred to as smart glasses, eye-wear devices, or simply eye-wear in this article) are new concepts. These devices are expected to process cellular data comparable to modern smart phones because these devices can download lenses, information about the current environment, and upload data to the cloud for processing. This means that the antenna architecture must be able to have very high radiation performance in terms of efficiency and isolation, and do all of this when worn on the user's head. However, the current construction of AR devices does not allow for best practices such as isolation and tuning to be followed. Wearable devices with AR capabilities are first of all wearable devices similar to smart watches, rather than rectangular boxes similar to smart phones, which means that appearance, weight, and thermal performance are key parameters. On mobile phones, circuit boards can be hidden behind the display. This is not possible for smart glasses because the display is perspective. As a result of the display arrangement of smart glasses, circuit boards must reside in other areas such as on the legs, which reduces the size available to them, which further reduces the volume available for a single antenna element, let alone multiple antenna elements. Weight and thermal performance requirements often limit the size of the batteries on these devices, which has a direct impact on the available computing power left to use advanced antenna tuners. Additionally, the human head is composed of brain tissue, which is known to absorb RF signals in the microwave frequency range, which is the range in which cellular systems operate. Current systems that take into account the proximity to the head and also address the other design criteria discussed in this article are only in early development.

[0028] Various embodiments of antenna systems according to the present disclosure will be described below with reference to an electronic device in the form of an example of an eye-wear device that includes the disclosed antenna system. Such an eye-wear device may include one or more cameras, indicator lights, memory, control circuitry, battery elements, and wireless communication circuitry, among other components. Reference will first be made to Figure 1 Example embodiments of such eyewear devices in which different embodiments of antenna systems may be incorporated are described, and reference will be made later to Figures 2A to 16 A series of different example embodiments of antenna systems and eye-wear devices incorporating different corresponding embodiments are described.

[0029] Figure 1 An oblique front view of an electronic device in the form of an example electronically-enabled eyewear device 100, also referred to as a pair of smart glasses, is shown. The eyewear device 100 includes a body 103 including a front piece or frame 106 and a pair of legs 109 movably connected to the frame 106 for supporting the frame 106 in position on the user's face when the eyewear device 100 is worn. The frame 106 can be made of any suitable material, such as plastic, a composite material, or a metal, including any suitable shape memory alloy.

[0030] The eyewear device 100 has a pair of optical elements in the example form of a pair of optical lenses 112, which are held by corresponding optical element holders or lens holders in the form of a pair of lens edges 115 that form part of the frame 106. The edges 115 are connected by a bridge 118. In other embodiments, one or both of the optical elements can be a display, a display assembly, or a combination of lenses and displays. In such an embodiment, the eyewear device 100 can provide a virtual reality headset or an augmented reality display.

[0031] The frame 106 includes a pair of end pieces 121 defining lateral ends of the frame 106. In this example, various electronic components are housed in one or both of the end pieces 121, as discussed in more detail below. In some embodiments, the frame 106 can be formed from a single piece of material so as to have a unitary or unitary construction.

[0032] The legs 109 are coupled to respective end pieces 121. In this example, the legs 109 are coupled to the frame 106 via respective hinges (hinged joints) so as to be able to be worn in a wearable mode (e.g. Figure 1The legs 109 are hingedly movable between a folded mode (shown) and a collapsed mode in which the legs 109 pivot toward the frame 106 to rest substantially flat against the frame 106. In other embodiments, the legs 109 can be coupled to the frame 106 by any suitable means. Each of the legs 109 includes a front portion coupled to the frame 106 and a suitable rear portion for coupling to the ear of the user, such as Figure 1 The curved ear hook is shown in the example embodiment of FIG.

[0033] In this specification, directional terms such as front, back, forward, rearward, outward, and inward will be understood with reference to the viewing direction of the user when the eyewear device 100 is worn. Thus, the frame 106 has an outwardly oriented front side 134 that faces away from the user when worn, and an opposite inwardly oriented rear side 137 that faces the user when the eyewear device 100 is worn. Similarly, the terms horizontal and vertical as used in this specification with reference to various features of the eyewear device 100 should be understood to correspond to the orientation of the eyewear device 100 when the eyewear device 100 is horizontally fitted on the face of a user looking forward. Thus, the horizontal or lateral direction of the eyewear device 100 extends generally between the end pieces 121, while the vertical or upright direction of the eyewear device 100 extends perpendicular to the horizontal direction, so that the lens 112 can be said to have a generally vertical or upright orientation.

[0034] The eyewear device 100 has onboard electronic components 124 (sometimes referred to herein simply as electronic devices or components), including any one or combination of an antenna system (discussed further below), a camera, a microphone, a speaker, a battery, a display device, a computing device such as a computer, which in various embodiments can be of any suitable type to be carried by the body 103. In some embodiments, the various components including the onboard electronic components 124 are at least partially housed in one or both of the legs 109. In this embodiment, the various components of the onboard electronic components 124 are housed in the lateral end pieces 121 of the frame 106. As described above, the onboard electronic components 124 include one or more processors as well as memory, wireless communication circuitry, and a power source (this example embodiment is a rechargeable battery, such as a lithium-ion battery). The onboard electronic components 124 include low-power, high-speed circuitry, and in some embodiments, a display processor. Various embodiments may include these elements in different configurations or integrated together in different ways. At least some of the electronic components of the antenna system described herein can be housed in one or both of the end pieces 121. Thus, for example, in some embodiments, certain electronic components, such as a cellular transceiver, may be housed in one of the end pieces 121 rather than in the legs 109, as discussed and illustrated further below.

[0035] As mentioned above, the on-board electronics 124 include a rechargeable battery. In some embodiments, the battery is disposed in one of the legs 109. However, in this example embodiment, the battery is housed in one of the end pieces 121, electrically coupled to the rest of the on-board electronics 124.

[0036] The eye-wearing device 100 is camera-enabled, including in this example a camera 130 mounted in one of the end pieces 121 and facing forward so as to be generally aligned with the viewing direction of the wearer of the eye-wearing device 100. The camera 130 is configured to capture digital still content as well as digital video content. The operation of the camera 130 is controlled by a camera controller provided by the on-board electronics 124, and image data representing images or videos captured by the camera 130 is temporarily stored on a memory forming part of the on-board electronics 124. In some embodiments, the eye-wearing device 100 may have, for example, a pair of cameras 130 housed by respective end pieces 121.

[0037] The eye-wearing device 100 also includes one or more input and output devices that allow communication with and control of the camera 130. In particular, the eye-wearing device 100 includes one or more input mechanisms for enabling a user to control one or more functions of the eye-wearing device 100. In this embodiment, the input mechanism includes a button 117 mounted on the frame 106 so as to be accessible on top of one of the end pieces 121 for the user to press.

[0038] In this example embodiment, the eye-wearing device 100 is configured for wireless communication with external electronic components or devices, and for this purpose, the on-board electronics 124 are connected to an antenna system integrated in the body 103 of the eye-wearing device 100 .

[0039] Go to Figure 2A and Figure 2B , the eye-wearing device 100 can be equipped with an antenna system 200 including a first antenna 202. The first antenna 202 can be configured as a loop conductor 204. The loop conductor 204 can form a part of the antenna system 200. Figure 2A and Figure 2B In the example of the embodiment of the present invention, the loop conductor 204 is provided by the lens edge 115, for example. More specifically, the lens edge 115 can be a part of the frame 106 and can be made of metal, metal alloy or other suitable conductive material so as to be operable as the first antenna 202. The lens edge 115 and the first antenna 202 can be used as a lens holder for holding the lens 112. Note that in Figure 2A and Figure 2B, only one of the lens edges 115 is shown as having a corresponding first antenna 202 / loop conductor 204 housed therein. However, other embodiments contemplate portions of both lens edges 115 being used as antennas / conductors, as discussed further herein.

[0040] exist Figure 2A and Figure 2B In some embodiments, the first antenna 202 is constructed by the frame 106 itself. However, other embodiments disclosed herein contemplate that the frame 106 is constructed of a non-conductive or semi-conductive material such as a rigid plastic, and the first antenna 202 can be a separate component coupled to the frame 106 by embedding, insert molding, or other known techniques.

[0041] The first antenna 202 as part of the lens edge 115 can be positioned to extend circumferentially around a portion, such as a majority, of the perimeter of the lens 112. The lens edge 115 and antenna 202 are engageable with the radially outer edge of the lens 112. This configuration holds the lens 112.

[0042] The eyewear device 100 including the lens 112 can have a configuration as described in U.S. Patent Nos. 9,726,904, entitled “EYEWEAR WITH CONDUCTIVE TEMPLE JOINT” (filed on September 29, 2015); 9,482,882, entitled “EYEWEAR HAVING SELECTIVELY EXPOSABLE FEATURE” (filed on April 15, 2015); and 9,482,883, entitled “EYEWEAR HAVING LINKAGE ASSEMBLY BETWEEN ATEMPLE AND AFRAME” (filed on April 15, 2015), 10,877,293, entitled “EYEWEAR DEVICE LENS RETENTION MECHANISM" (filed on January 18, 2018), U.S. Patent No. US11,063,338, entitled "HYBRID ANTENNA SYSTEM FORWEARABLE DEVICES" (filed on January 24, 2019), U.S. Patent No. US10,534,203, entitled "NEAR-FIELD ANTENNA FOR EYEWEAR" (filed on July 31, 2017), the contents of all of which are incorporated herein in their entirety.

[0043] According to one example, the lens 112 may be composed of chemically strengthened lithium aluminosilicate (LAS) glass. Example properties of such glass are shown in Table 1 below:

[0044]

[0045]

[0046] Table 1

[0047] The first antenna 202 of the disclosed eyewear device 100 can benefit from the fact that the lens 112 can be optically efficient. The chemical nature of these optically transparent, extremely low-loss materials when used for the lens 112 means that the construction of the lens 112 also has extremely low energy losses at the RF microwave bands where cellular systems operate. Therefore, when coupled to the first antenna 202 (and other antenna constructions discussed herein), the lens 112 as contemplated herein can constitute a perfect antenna substrate. Therefore, it is advantageous to place the first antenna 202 around the lens 112 and couple the first antenna 202 to the lens 112.

[0048] Due to the advantageous properties of the lens 112, it is also contemplated that the first antenna 202 may be constructed within the lens 112 of the eyewear device 100 instead of being constructed (or housed) in the frame 106, or in addition to being constructed (or housed) in the frame 106. Figure 2B As best shown in FIG. 1 , the first antenna 202 is formed by the frame 106 and is configured to form a loop for a current path (indicated by arrows) around substantially the entire lens 112. Figure 2B As shown, a current path may be generated (energized) at or adjacent to a gap 206 filled by an electrically insulating material (e.g., plastic, etc.) in the frame 106. The current path may terminate at or adjacent to the other side of the frame 106 from the gap 206.

[0049] therefore, Figure 2A and Figure 2B The example of illustrative embodiments shows an arrangement in which a loop conductor 204 can extend circumferentially around one of a pair of lenses 112 (or, in some embodiments, other optical elements such as virtual reality or augmented reality display elements) held by the eyewear device 100. One or more of the lenses 112 can be held by the loop conductor 204 / first antenna 202 as part of the antenna system 200. More specifically, by engaging the radial periphery of the associated lens 112, the loop conductor 204 / first antenna 202 can hold the lens 112 in position relative to the frame 106.

[0050] An advantage of placing the first antenna 202 to be coupled to, within, or in close proximity to the lens 112 is that the antenna design utilizes the user's eye cavity when the eye-wearing device 100 is worn. The eye cavity forms a natural separation between the frame 106 of the eye-wearing device 100 and the brain tissue in the head, which has significant RF energy absorption properties. This separation greatly contributes to the radiation efficiency of the antennas because they have the opportunity to radiate outside the user's body rather than into the brain tissue.

[0051] Figure 3A and Figure 3B The first antenna 202 ( Figure 2A and Figure 2B ) is a radiation pattern associated with the operation of the eye-wearing device 100. As shown, the construction of the first antenna 202 forms a beam that radiates away from the face of the user 300. The peak radiation (indicated by arrow A) is in a direction away from the user 300. Due to the curvature of the face and the way the user 300 wears the eye-wearing device 100, this peak radiation can be tilted downward. In other words, the circular RF current will generate a magnetic field orthogonal to the surface of the lens 112, radiating toward the outside world. The eye cavity will provide these fields with a much-needed separation from the head to achieve maximum radiation efficiency and minimize the specific absorption rate (SAR) for radiation, which is a regulatory metric for wireless system compliance.

[0052] Figure 4 is similar in construction to the previously discussed Figures 1 to 2A 1. A highly schematic diagram of an eyewear device 100A similar or identical to the eyewear device 100 of FIG. 1. The eyewear device 100A includes a frame 106, a lens 112, a leg 109, and one or more onboard electronic components 124. The eyewear device 100A further includes an antenna system 400 including a first antenna 402, a second antenna 404, and a transceiver 406. The eyewear device 100A further includes a hinge 408, a frame electrical connection 410, and a leg electrical connection 412.

[0053] The frame 106 may be configured to hold one or more optical elements (e.g., lens 112). The legs 109 may be connected to the frame 106, for example, via hinges 408 (an example of an articulated joint). Via hinges 408, the legs may be able to be in a folded state (not shown) with the Figure 4 404. In the wearable state, the eyewear device 100A can be worn by the user to keep one or more optical elements within the user's field of view. In addition, when in the wearable state, the leg and its components including the second antenna 404 can be oriented substantially orthogonal to the frame 106 and the first antenna 402.

[0054] In addition to the first antenna 402, the second antenna 404, and the transceiver 406, the antenna system 400 may also include a frame electrical connection 410 and a leg electrical connection 412. The frame electrical connection 410 and the leg electrical connection 412 may allow electronic communication and other functions using the first antenna 402 and the second antenna 404. The first antenna 402 may have a structure similar to Figure 2A and Figure 2B However, the first antenna 402 may differ in that the first antenna 402 is not formed from the material of the frame 106 (e.g., such as a conductive metal or metal alloy), but may be a different separate component coupled to the frame 106, such as by embedding, insert molding, or other known manufacturing techniques.

[0055] The second antenna 404 may be carried by the leg 109, such as Figure 4 The orientation of the leg 109 in the wearable state may orient the second antenna 404 substantially orthogonally to the plane of the first antenna 402, which may be desirable to reduce overlap between the first antenna 402 and the second antenna 404. Figure 4 As shown, the second antenna 404 can be configured as a loop antenna (which can utilize a conductive loop). This allows the second antenna 404 to have a radiation pattern similar to the first antenna 402, but in a direction substantially orthogonal thereto, such as Fig. 12A and Fig. 12B shown.

[0056] Figure 4 Only exemplary arrangements and configurations for the first antenna 402 and the second antenna 404 are provided, and other arrangements and configurations are contemplated. Other contemplated arrangements and configurations may orient the second antenna 404 substantially orthogonally to the plane in which the first antenna 402 lies.

[0057] Figure 5 This is consistent with the previously discussed Figures 1 to 2A Eyewear device 100 and Figure 4 10A. The eyewear device 100B includes a frame 106, a lens 112, a leg 109, and one or more onboard electronic components 124. The eyewear device 100B additionally includes an antenna system 500, which includes a first antenna 502, a second antenna 504, and a transceiver 406. As previously discussed, the eyewear device 100B also includes a hinge 408, a frame electrical connection 410, and a leg electrical connection 412.

[0058] Figure 5The eye-wearing device 100B differs from the previous examples in that the second antenna 504 can have a different construction than the first antenna 502 and can be carried by the frame 106 instead of the leg 109. While the first antenna 502 can be constructed as a loop antenna as previously discussed, the second antenna 504 is a non-loop antenna (sometimes referred to as an incomplete loop, dipole, or monopole antenna). Typically, a non-loop antenna includes a linear (but not necessarily straight) non-loop conductor. For a monopole antenna, the signal feed point is connected to the non-loop conductor at the end of the conductor, while the signal feed point in a dipole antenna divides the dipole conductor into two linear arms. In contrast, a loop antenna (such as the first antenna 502) includes a loop conductor whose ends are connected to a signal feed point or transmission line. It is important to note that dipole antennas are also referred to herein as "electrical" or "E-type" antennas because their primary radiation pattern is TM. 10 This means that the antenna generates an electric field orthogonal to the direction of propagation. Similarly, loop antennas are called "magnetic" antennas because their primary radiation pattern is TE 10 , which means that the antenna generates a magnetic field orthogonal to the direction of propagation.

[0059] Figure 5 An example of a dipole loop or monopole loop hybrid antenna system 500 is provided. Figure 5 The antenna system 500 combines two basic antenna types, namely the first antenna 502 is a loop antenna and the second antenna 504 can be a dipole antenna or a monopole antenna. This provides the following structure, where the TM 10 and TE 10 Efficient radiation of mode support is possible. Figure 5 The antenna system 500 is essentially a superposition of a loop antenna and a dipole antenna, wherein their radiation patterns are orthogonal to each other, and wherein the loop antenna and the dipole antenna radiate with different polarizations.

[0060] It should be noted that the second antenna 504 can be positioned to be coupled to or in close proximity to the lens 112, as discussed with respect to the previous examples of the first antenna (including the first antenna 502). Such positioning for the second antenna 504 is Figure 5 However, although such an arrangement may be beneficial for the reasons discussed above, the location of the second antenna 504 on the frame 106 is not limited to Figure 5 , and other locations of the second antenna 504 on or as part of the frame 106 (or on or as part of the leg 109) are contemplated.

[0061] The second antenna 504 can be formed by the frame 106, or can be a separate component coupled to the frame (e.g., by embedding, insert molding, or other techniques as previously discussed). If formed separately from the frame 106, the second antenna 504 (and / or the first antenna 502) can be formed from a wire (e.g., copper wire, aluminum wire, nickel wire, etc.) embedded in the molded polymer plastic material of the eyewear device frame 106. The antenna can be part of a core wire that is used to provide structural integrity or rigidity to the frame 106 (or the legs 109 in some embodiments).

[0062] Figure 5 An example of antenna system 500 utilizing portions of antenna system 500 , namely cellular transceiver 506 carried by leg 109 and leg electrical connection 412 , is shown.

[0063] Figure 6 An eye-wearing device 100C is shown, which is Figure 5 The eye-wear device 100C differs in that one or more on-board electronic components 124, including portions of the antenna system 500C, have been eliminated from the leg (not shown). The eye-wear device 100C with the antenna system 500C includes a first antenna 502, a second antenna 504, and a transceiver 406. The eye-wear device 100C also includes a hinge 408 and a frame electrical connection 410. The leg electrical connection 412 ( Figure 5 ) has been eliminated. In other words, Figure 6 In the example of FIG. 5 , antenna system 500C including transceiver 406 is completely carried by frame 106 .

[0064] Figure 7 As shown previously in Figure 5 An example of an eyewear device 100B is shown in the schematic diagram of . The eyewear device 100B can be equipped with an antenna system 500 having a first antenna 502 and a second antenna 504. The first antenna 502 can be coupled to the lens 112 and can be part of the frame 106 as previously discussed. The second antenna 504 can be coupled to the second lens 112A or can be adjacent to the second lens 112A and can include a non-loop antenna (e.g., a loaded monopole antenna) as previously discussed. Figure 7 As shown, the second antenna 504 can be formed by the frame 106. The frame 106 can be configured to hold the second lens 112A in the lens area. The second antenna 504 can be arranged around a relatively smaller portion of the periphery of the second lens 112A than the portion of the periphery of the lens 112 coupled to the first antenna 502.

[0065] The second antenna 504 requires two non-conductive gaps 514 and 516 in the frame 106. One gap 514 is used for excitation and the other gap 516 is used to terminate the loaded monopole antenna. In this antenna design for the second antenna 504, the electric fields generated by the RF current will be tangential to the surface of the lens 112A, radiating towards the head and the outside world. The eye cavity will provide these fields with much needed separation from the head for maximum radiation efficiency. In addition to the loop design of the first antenna 502, using the second antenna 504 as a loaded monopole design can provide flexibility, allowing two different antennas to be specifically tailored to specific operating cellular bands.

[0066] So, for example, Figure 7 A hybrid antenna system is disclosed having a loop antenna at the periphery of one lens (coupled to or in close proximity to the lens) and a dipole or monopole antenna at another lens (coupled to or in close proximity to the lens), wherein the two different antennas are connected to a transceiver and configured to receive a common cellular (or other wireless) signal.

[0067] Figure 7 Arrowed current paths are shown for both the first antenna 502 and the second antenna 504, including current generation at or adjacent to gap 514 and current termination at or adjacent to gap 516 for the second antenna.

[0068] Figure 7 The antenna system 500 in Figure 8 As shown schematically in Figure 7 and Figure 8 As shown, the loop antenna provides large radiation efficiency and excellent SAR performance. The H field generated by this antenna is perpendicular to the glass lens surface, and the peak radiation occurs toward the sky and the ground. The loaded monopole antenna provides good antenna radiation performance. The E field generated by this antenna is tangential to the glass lens surface, and the peak radiation occurs toward the head and away from the eyes. Therefore, the loop antenna and the loaded monopole antenna have essentially orthogonal radiation fields, which technically translates into excellent isolation characteristics (ideally zero or minimal correlation). Therefore, the antenna architecture candidate for the AR wearable device will have a loop antenna around one glass lens, and a loaded monopole antenna around the other lens. Due to its excellent SAR performance, the loop antenna will be responsible for both uplink and downlink ( Figure 8 The loaded monopole will be a perfect candidate for the main cellular antenna element responsible for the downlink (T / RX) Figure 8 The perfect candidate for auxiliary cellular antenna element for RX in the RF field. Figure 8As shown, the cellular RF front end (including the cellular transceiver) can be located at the center or frame 106, just above the nose pads, to minimize the path loss connecting the cellular transceiver to the antenna elements. Figure 8 Shown in.

[0069] Fig. 9 and Fig.10 An eyewear device 100D is shown with an antenna system 600. The frame 106 can carry at least one antenna 602 of the antenna system 600. As previously discussed, the at least one antenna 602 can be located at or adjacent to the lens 112, e.g., coupled to the lens 112. The antenna system 600 can include a second antenna 604 and a transceiver 606, as well as other electronic components in one or more electronic components 124 carried by the leg 109.

[0070] Fig. 9 A portion of the housing 608 of the leg 109 is shown cut away to show the second antenna 604 and the transceiver 606 . Fig.10 The housing of the legs 109 is shown completely removed. Fig.10 As shown, the second antenna 604 can be coupled to the speaker carrier 610.

[0071] exist Fig. 9 and Fig.10 In an embodiment, the second antenna 604 may be configured as a loop antenna. Fig.10 A current flow path is shown along the second antenna 604 to the cellular transceiver 606. The current path as shown shows the transmit point for the second antenna 604 and the ground termination point.

[0072] Since the leg 109 can be arranged to be substantially orthogonal to the frame 106 when in the wearable state as previously discussed and shown, such an arrangement can maximize the isolation of one or more antennas 602 of the frame 106 from the second antenna 604 of the leg 109. In order to maximize the isolation between the two antennas 602 and 604, if one or more antennas 602 on the frame 106 are configured as loop antennas, the second antenna 604 should also be configured as a loop antenna. However, if one or more antennas 602 on the frame 106 are configured as non-loop antennas, the second antenna 604 should also be configured as a non-loop antenna. Although the second antenna 604 is shown as being placed on the speaker carrier 608, the second antenna 604 can be placed in another location such as on the main PCB itself.

[0073] Fig.11A and Fig. 11BShown in more detail is a second antenna 604 coupled to a speaker carrier 610. Since speaker systems typically require a carrier to transport air from the driver elements to the outside world, they must utilize one or more cavities. Fig.11A A speaker port 612 is shown providing a cavity in the speaker carrier 610. The cavities inside these carriers are carefully designed to provide amplification of audible frequencies and suppress unwanted frequencies. The cavity walls are typically made of an RF-friendly plastic material and filled with air. Therefore, designing a second antenna 604 to be attached to the outer surface of the speaker carrier provides an excellent dual use opportunity. The second antenna 604 can be designed as stamped metal, a flexible printed circuit board, or can be embedded in the speaker carrier 610 via a laser direct structuring process.

[0074] Fig. 12A and Fig. 12B The second antenna 604 ( Figures 9 to 11B ). As shown, the configuration of the second antenna 604 forms a beam that radiates away from the face and ears of the user 300. The peak radiation (indicated by arrow A) is away from the user 300. As shown in Table 2 below, a very low level of correlation between the two antennas is shown. Therefore, the two antennas operate essentially independently of each other.

[0075]

[0076] Table 2

[0077] Fig.13 shows a structure similar to that discussed previously. Figure 4 10A of the eyewear device 100E. The eyewear device 100E includes a frame 106, a lens 112, a leg 109, and one or more onboard electronic components 124. The eyewear device 100E further includes an antenna system 700, which includes a first antenna 702, a second antenna 704, and a transceiver 406. The eyewear device 100E further includes a hinge 408, a frame electrical connection 410, and a leg electrical connection 412, as previously described with reference to FIG. Figure 4 discussed.

[0078] Antenna system 700 with Figure 4 The antenna system of FIG. 1 is different in that the first antenna 702 is a non-loop antenna and the second antenna 704 is a non-loop antenna. The first antenna 702 can be carried by the frame 106 (e.g., can be part of the frame 106 or can be a separate component from the frame 106, coupled to the frame 106 as previously discussed). The second antenna 704 can be carried by the leg 109.

[0079] Fig.14An eye-wearable device 100F is shown having an antenna system 800 including three or more antennas 802A, 802B, and 802C that may be configured and utilized according to the principles discussed herein for cellular communications.

[0080] Fig.15 is a block diagram 900 illustrating a software architecture 902 that may be installed on any one or more of the glasses or an accompanying host device (e.g., a smart phone), a glasses case, a charging source, or other system coupled to the glasses. Fig.15 This is merely a non-limiting example of a software architecture 902, and it will be appreciated that many other architectures may be implemented to facilitate the functionality described herein. In various embodiments, the software architecture 902 is implemented by hardware such as Fig.16 1100, which includes a processor 1110, a memory 1130, and an I / O component 1150. In this example architecture, the software architecture 902 can be conceptualized as a stack of layers, each of which can provide specific functionality. For example, the software architecture 902 includes layers such as an operating system 904, a library 906, a framework 908, and an application 910. In operation, consistent with some embodiments, the application 910 activates an application programming interface (API) call 912 through the software stack and receives a message 914 in response to the API call 912.

[0081] In various implementations, the operating system 904 manages hardware resources and provides public services. The operating system 904 includes, for example, a kernel 920, services 922, and drivers 924. Consistent with some embodiments, the kernel 920 acts as an abstraction layer between the hardware and other software layers. For example, the kernel 920 provides memory management, processor management (e.g., scheduling), component management, networking and security settings, and other functions. Services 922 can provide other public services to other software layers. According to some embodiments, the drivers 924 are responsible for controlling or connecting to the underlying hardware. For example, the drivers 924 may include a display driver, a camera driver, or Low-power drivers, Flash drivers, Serial communications drivers (e.g., Universal Serial Bus (USB) drivers), Cellular drivers, Drivers, audio drivers, power management drivers, etc.

[0082] In some embodiments, the library 906 provides a low-level common infrastructure utilized by the application 910. The library 906 may include a system library 930 (e.g., a C standard library), which may provide functions such as memory allocation functions, string manipulation functions, mathematical functions, etc. In addition, the library 906 may include an API library 932, such as a media library (e.g., a library that supports the presentation and manipulation of various media formats, such as Moving Picture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), a graphics library (e.g., an OpenGL framework for rendering graphics content in two dimensions (2D) and three dimensions (3D) on a display), a database library (e.g., SQLite for providing various relational database functions), a web library (e.g., WebKit for providing web browsing functions), etc. The library 906 may also include a variety of other libraries 934 to provide many other APIs to the application 910.

[0083] According to some embodiments, the framework 908 provides a high-level common infrastructure that can be utilized by the applications 910. For example, the framework 908 provides various graphical user interface (GUI) functions, advanced resource management, advanced location services, etc. The framework 908 can provide a wide range of other APIs that can be utilized by the applications 910, some of which can be specific to a particular operating system 904 or platform.

[0084] In an example embodiment, applications 910 include a home application 950, a contacts application 952, a browser application 954, a book reader application 956, a location application 958, a media application 960, a messaging application 962, a game application 964, and various other applications such as third-party applications 966. According to some embodiments, application 910 is a program that performs the functions defined in the program. Various programming languages ​​can be used to create one or more applications 910 constructed in various ways, such as an object-oriented programming language (e.g., Objective-C, Java, or C++) or a procedural programming language (e.g., C or assembly language). In a specific example, third-party application 966 (e.g., a third-party application created by an entity other than the vendor of a particular platform using ANDROID TM or IOS TM Applications developed with a software development kit (SDK) 910) can be developed on mobile operating systems such as IOS TM ANDROID TM , Mobile software running on the phone or other mobile operating system. In this example, third-party applications 966 can activate API calls 912 provided by the operating system 904 to facilitate the functions described herein.

[0085] Some embodiments may specifically include a curation application 967. In certain embodiments, this may be a stand-alone application that operates to manage communications with the server systems. In other embodiments, this functionality may be integrated with another application such as the media application 960 or another such application. The curation application 967 may manage collections of content using the camera device of the machine 1100, communications with the server systems via the I / O components 1150, and receiving and storing received media collections in the memory 1130. The presentation of content and user input associated with the content may be managed by the curation application 967 using different frameworks 908, library 906 elements, or operating system 904 elements operating on the machine 1100.

[0086] Fig.16 1 is a block diagram illustrating components of a machine 1100 capable of reading instructions from a machine-readable medium (e.g., a machine-readable storage medium) and performing any one or more of the methods discussed herein, according to some embodiments. Specifically, Fig.16 A diagrammatic representation of a machine 1100 in the example form of a computer system within which instructions 1116 (e.g., software, programs, applications 910, applet, app, or other executable code) may be executed for causing the machine 1100 to perform any one or more of the methodologies discussed herein. In alternative embodiments, the machine 1100 operates as a standalone device or may be coupled (e.g., using a network) to other machines. In a networked deployment, the machine 1100 may operate in the capacity of a server or a device in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 1100 may include, but is not limited to, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a set-top box (STB), a personal digital assistant (PDA), an entertainment media system, a cellular phone, a smart phone, a mobile device, a wearable device (e.g., a smart watch), a smart home device (e.g., a smart appliance), other smart devices, a web appliance, a network router, a network switch, a network bridge, or any machine capable of executing instructions 1116 that specify actions to be taken by the machine 1100, either sequentially or otherwise. In addition, while only a single machine 1100 is shown, the term "machine" should also be taken to include a collection of machines 1100 that individually or jointly execute instructions 1116 to perform any one or more of the methodologies discussed herein.

[0087] In various embodiments, the machine 1100 includes a processor 1110, a memory 1130, and an I / O component 1150, which can be configured to communicate with each other via a bus 1102. In an example embodiment, the processor 1110 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a radio frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) includes, for example, a processor 1112 and a processor 1114 that can execute instructions 1116. The term "processor" is intended to include a multi-core processor 1110, which can include two or more independent processors 1112, processors 1114 (also referred to as "cores") that can execute instructions 1116 simultaneously. Although Fig.16 Multiple processors 1110 are shown, but the machine 1100 may include a single processor 1110 with a single core, a single processor 1110 with multiple cores (e.g., a multi-core processor 1110), multiple processors 1112 and processor 1114 with a single core, multiple processors 1112 and processor 1114 with multiple cores, or any combination thereof.

[0088] According to some embodiments, the memory 1130 includes a main memory 1132, a static memory 1134, and a storage unit 1136, which are all accessible by the processor 1110 via the bus 1102. The storage unit 1136 may include a machine-readable medium 1138 on which are stored instructions 1116 embodying any one or more of the methods or functions described herein. The instructions 1116 may also reside completely or at least partially within the main memory 1132, within the static memory 1134, within at least one of the processors 1110 (e.g., within a cache memory of the processor), or within any suitable combination thereof during execution thereof by the machine 1100. Thus, in various embodiments, the main memory 1132, the static memory 1134, and the processor 1110 are considered to be a machine-readable medium 1138.

[0089] As used herein, the term "memory" refers to a machine-readable medium 1138 capable of temporarily or permanently storing data, and may be considered to include, but is not limited to, random access memory (RAM), read-only memory (ROM), buffer memory, flash memory, and cache memory. Although in the example implementation, the machine-readable medium 1138 is shown as a single medium, the term "machine-readable medium" should be considered to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) capable of storing instructions 1116. The term "machine-readable medium" should also be considered to include any medium or combination of multiple media capable of storing instructions (e.g., instructions 1116) for execution by a machine (e.g., machine 1100), such that the instructions 1116, when executed by one or more processors (e.g., processor 1110) of the machine 1100, cause the machine 1100 to perform any one or more of the methods described herein. Therefore, "machine-readable medium" refers to a single storage device or device, as well as a "cloud-based" storage system or storage network including multiple storage devices or devices. Thus, the term "machine-readable medium" shall be taken to include, but not be limited to, one or more data repositories in the form of solid-state memory (e.g., flash memory), optical media, magnetic media, other non-volatile memory (e.g., erasable programmable read-only memory (EPROM)), or any suitable combination thereof. The term "machine-readable medium" expressly excludes non-statutory signals per se.

[0090] I / O components 1150 include various components for receiving input, providing output, generating output, sending information, exchanging information, capturing measurement results, etc. In general, it should be understood that I / O components 1150 may include Fig.16 Many other components not shown in the figure. The I / O components 1150 are grouped according to function only to simplify the following discussion, and the grouping is by no means limiting. In various example embodiments, the I / O components 1150 include output components 1152 and input components 1154. The output components 1152 include visual components (e.g., displays such as plasma display panels (PDPs), light emitting diode (LED) displays, liquid crystal displays (LCDs), projectors, or cathode ray tubes (CRTs)), auditory components (e.g., speakers), tactile components (e.g., vibration motors), other signal generators, etc. The input components 1154 include alphanumeric input components (e.g., keyboards, touch screens configured to receive alphanumeric input, optical keyboards, or other alphanumeric input components), point-based input components (e.g., mice, touch pads, trackballs, joysticks, motion sensors, or other pointing instruments), tactile input components (e.g., physical buttons, touch screens or other tactile input components that provide positioning and force of touch or touch gestures), audio input components (e.g., microphones), etc.

[0091] In some further example embodiments, the I / O component 1150 includes a biometric component 1156, a motion component 1158, a camera 1160, an environmental component or a position component 1162, and a variety of other components. For example, the biometric component 1156 includes components for detecting expressions (e.g., hand expressions, facial expressions, voice expressions, body postures, or eye tracking), measuring biosignals (e.g., blood pressure, heart rate, body temperature, sweat, or brain waves), identifying people (e.g., voice recognition, retinal recognition, facial recognition, fingerprint recognition, or EEG-based recognition), etc. The motion component 1158 includes an acceleration sensor component (e.g., an accelerometer), a gravity sensor component, a rotation sensor component (e.g., a gyroscope), etc. The environmental components include, for example, lighting sensor components (e.g., photometers), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometers), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensor components (e.g., machine olfactory detection sensors, gas detection sensors that detect concentrations of hazardous gases for safety or measure pollutants in the atmosphere), or other components that can provide indications, measurements, or signals corresponding to the surrounding physical environment. The camera device components include any information used for image capture, such as saturation control, pixel processing, sound capture, three-dimensional image processing, etc. The location component 1162 includes a positioning sensor component (e.g., a global positioning system (GPS) receiver component), an altitude sensor component (e.g., an altimeter or barometer that detects air pressure, from which the altitude can be obtained), an orientation sensor component (e.g., a magnetometer), etc.

[0092] Various technologies may be used to implement communications. I / O components 1150 may include communications components 1164 that are operable to couple machine 1100 to network 1180 or device 1170 via coupler 1182 and coupler 1172, respectively. For example, communications components 1164 include a network interface component or another suitable device for interfacing with network 1180. In other examples, communications components 1164 include wired communications components, wireless communications components, cellular communications components, near field communications (NFC) components, Components (e.g. Low power consumption), Device 1170 may be another machine or any of a variety of peripheral devices (eg, a peripheral device coupled via a universal serial bus (USB)).

[0093] In addition, in some embodiments, the communication component 1164 detects the identifier or includes a component operable to detect the identifier. For example, the communication component 1164 includes a radio frequency identification (RFID) tag reader component, an NFC smart tag detection component, an optical reader component (e.g., an optical sensor for detecting one-dimensional bar codes such as universal product codes (UPC) bar codes, multi-dimensional bar codes such as quick response (QR) codes, Aztec codes, data matrix, data symbols (Dataglyph), maximum code (MaxiCode), PDF417, Ultra Code, Uniform Commercial Code Reduced Space Symbol (UCC RSS)-2D bar codes, and other optical codes), an acoustic detection component (e.g., a microphone for identifying a tagged audio signal), or any suitable combination thereof. In addition, various information can be obtained via the communication component 1164, such as obtaining positioning via Internet Protocol (IP) geolocation, obtaining positioning via Signal triangulation is used to determine the location of the signal, which can be detected to indicate a specific location. Or NFC beacon signal to get positioning, etc.

[0094] In various example embodiments, one or more portions of network 1180 may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of a public switched telephone network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, 1180 may include a wireless or cellular network, other types of networks, or a combination of two or more such networks. For example, network 1180 or a portion of network 1180 may include a wireless or cellular network, and coupling 1180 may be a code division multiple access (CDMA) connection, a global system for mobile communications (GSM) connection, or another type of cellular or wireless coupling. In this example, coupling 1182 may implement any of various types of data transmission technologies, such as single carrier radio transmission technology (1xRTT), evolution data optimized (EVDO) technology, general packet radio service (GPRS) technology, enhanced data rates for GSM evolution (EDGE) technology, the third generation partnership project (3GPP) including 3G, fourth generation wireless (4G) networks, universal mobile telecommunications system (UMTS), high speed packet access (HSPA), world wide interoperability for microwave access (WiMAX), long term evolution (LTE) standards, other standards defined by various standard setting organizations, other long distance protocols, or other data transmission technologies.

[0095] In an example embodiment, instructions 1116 are sent or received over network 1180 using a transmission medium via a network interface device (e.g., a network interface component included in communication component 1164) and utilizing any of a number of well-known transmission protocols (e.g., Hypertext Transfer Protocol (HTTP)). Similarly, in other example embodiments, instructions 1116 are sent or received using a transmission medium via a coupling 1172 (e.g., a peer-to-peer coupling) with device 1170. The term "transmission medium" shall be taken to include any intangible medium capable of storing, encoding, or carrying instructions 1116 for execution by machine 1100, and includes digital or analog communication signals or other intangible media to facilitate communication of such software.

[0096] Furthermore, the machine-readable medium 1138 is non-transitory (in other words, does not have any transient signals) because it does not embody propagating signals. However, labeling the machine-readable medium 1138 as "non-transitory" should not be interpreted to mean that the medium cannot be moved; the medium 1138 should be considered to be transportable from one physical location to another. Additionally, because the machine-readable medium 1138 is tangible, the medium 1138 can be considered a machine-readable device.

Thus, for example, the disclosed antenna systems may be advantageously used in other wearable electronic devices, mobile electronic devices (such as mobile phones, tablet computers, etc.), and / or larger products such as motor vehicles.
