Description

Technical Field

[0001] This disclosure relates to the field of electronic product technology, specifically to a watch. Background Technology

[0002] Currently, due to limitations in circuitry and space, smartwatches typically use ground-based linearly polarized antennas, while satellite communications usually transmit right-hand circularly polarized waves. This causes the antennas in smartwatches to lose at least 3dB of performance simply due to polarization mismatch, resulting in poor antenna performance in smartwatches. Summary of the Invention

[0003] This disclosure provides a watch that can improve communication performance between the watch and a satellite.

[0004] In a first aspect, the present disclosure provides a watch, including a watch body and a first antenna element and a second antenna element disposed around the periphery of the watch body. The first antenna element and the second antenna element are respectively annular, and the second antenna element is coaxially disposed with the first antenna element. The second antenna element and the first antenna element have a first state of being far apart from each other and a second state of being close to each other.

[0005] Wherein, when the first antenna element and the second antenna element are in the first state, the first antenna element and the second antenna element form a circularly polarized Yagi antenna;

[0006] When the first antenna element and the second antenna element are in the second state, the first antenna element and the second antenna element together form the radiator of the antenna.

[0007] In this embodiment, since the first antenna element and the second antenna element have a first state of being far apart from each other and a second state of being close together, when the antenna is in a non-operating state, the first antenna element and the second antenna element can be controlled to be in the second state to reduce the space occupied by the antenna. When the antenna is in an operating state, the first antenna element and the second antenna element can be controlled to be in the first state so that the first antenna element and the second antenna element can form a circularly polarized Yagi antenna, thereby achieving high satellite communication performance.

[0015] The technical solutions of the embodiments of this disclosure will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0016] The terms "first," "second," etc., used in this disclosure and in the claims are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] The watch provided in this disclosure will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0018] Please see Figure 1-7 , Figure 1-7This is a schematic diagram of the structure of a watch provided in an embodiment of the present disclosure. The watch includes a watch body and a first antenna element 120 and a second antenna element 130 disposed around the periphery of the watch body. The first antenna element 120 and the second antenna element 130 are respectively annular, and the second antenna element 130 is coaxially disposed with the first antenna element 120. The second antenna element 130 and the first antenna element 120 have a first state of being far apart from each other and a second state of being close together. In the first state, the first antenna element 120 and the second antenna element 130 form a circularly polarized Yagi antenna. In the second state, the first antenna element 120 and the second antenna element 130 together form the radiator of the antenna.

[0019] The watch can be any type of smartwatch. The diameter of the first antenna element 120 can be the same as the diameter of the second antenna element 130, and the first antenna element 120 and the second antenna element 130 can be antenna elements made of conductive material.

[0020] It is understood that the circuit board 110 can be the main circuit board 110 in a watch, and the circuit board 110 can be equipped with a feed source. The circuit board 110 is electrically connected to the feed point through the feed source to feed an antenna signal to the feed point. When the feed source feeds the antenna signal to the feed point, the antenna signal can be radiated through the first antenna element 120 and the second antenna element 130. Furthermore, the first antenna element 120 and the second antenna element 130 can also receive external antenna signals.

[0021] Due to users' habit of facing the watch face upwards when using smartwatches for communication, and the characteristic of Yagi antennas achieving a high directional pattern within narrow bands, a reconfigurable circularly polarized antenna element is constructed to suit the limited size of smartwatches. Based on this, this disclosure constructs two circularly polarized antenna elements on the smartwatch face. During normal use, the two antenna elements can be tightly meshed on the same watch face plane, emphasizing the size of the terminal. When satellite communication is required, the elements are popped out, forming a circularly polarized Yagi antenna pointing upwards towards the watch face, thereby achieving high satellite communication performance.

[0022] The aforementioned watch may further include a driving component for switching the second antenna vibrator 130 and the first antenna vibrator 120 between a first state and a second state. The driving component can move at least one of the second antenna vibrator 130 and the first antenna vibrator 120 to switch between the first and second states. For example, the driving component can be various driving components capable of outputting reciprocating linear motion, such as a telescopic motor, a crank-slider drive mechanism, a lead screw-nut drive mechanism, etc. In one embodiment of this disclosure, the power output terminal of the driving component can be connected to the second antenna vibrator 130 to move the second antenna vibrator 130 toward or away from the first antenna vibrator 120, thereby achieving the switching between the two states. As another example, in another embodiment of this disclosure, the power output terminal of the driving component can be connected to the first antenna vibrator 120 to move the first antenna vibrator 120 toward or away from the second antenna vibrator 130, thereby achieving the switching between the two states.

[0023] In this embodiment, since the first antenna element 120 and the second antenna element 130 have a first state of being far apart from each other and a second state of being close together, when the antenna is in a non-operating state, the first antenna element 120 and the second antenna element 130 can be controlled to be in the second state to reduce the space occupied by the antenna. When the antenna is in an operating state, the first antenna element 120 and the second antenna element 130 can be controlled to be in the first state, so that the first antenna element 120 and the second antenna element 130 can form a circularly polarized Yagi antenna, thereby achieving high satellite communication performance.

[0024] Optionally, the first antenna element 120 is fixedly connected to the watch body, and the second antenna element 130 is located on the side of the first antenna element 120 facing away from the watch body. The second antenna element 130 can move toward or away from the first antenna element 120 so that the second antenna element 130 and the first antenna element 120 switch between the first state and the second state.

[0025] It is understood that the watch may include a driving component for moving the second antenna vibrator 130 toward or away from the first antenna vibrator 120. The driving component may be any of the driving components described in the above embodiments that can output reciprocating linear motion, such as a telescopic motor, a crank-slider drive mechanism, a lead screw-nut drive mechanism, etc.

[0026] In this embodiment, two circularly polarized antenna elements are constructed on the smartwatch dial, with one element popping out in the upward direction of the dial to form a Yagi antenna with the other. During normal use, the two antenna elements can be tightly meshed on the same dial plane, emphasizing the size of the terminal; when satellite communication is required, the popped element forms a circularly polarized Yagi antenna pointing upwards towards the dial, thereby achieving high satellite communication performance.

[0027] Optionally, the watch body includes a retractable housing (not shown in the figure), and the first antenna element 120 and the second antenna element 130 are respectively connected to the housing;

[0028] During the extension of the housing, the housing drives the first antenna element 120 and the second antenna element 130 to move away from each other, so that the second antenna element 130 and the first antenna element 120 switch from the second state to the first state;

[0029] During the retraction of the housing, the housing drives the first antenna vibrator 120 and the second antenna vibrator 130 to move towards each other, so that the second antenna vibrator 130 and the first antenna vibrator 120 switch from the first state to the second state.

[0030] It is understood that the aforementioned housing can be any type of housing capable of outputting telescopic movement. For example, in one embodiment of this disclosure, the housing includes an annular base, a first annular sub-housing, a second annular sub-housing, a first driving member, and a second driving member. The first annular sub-housing, the annular base, and the second annular sub-housing are coaxially arranged and located at opposite ends of the annular base. The first driving member can be installed within the annular base, and its power output end is connected to the first annular sub-housing to drive the first annular sub-housing to move towards or away from the annular base. Correspondingly, the second driving member can be installed within the annular base, and its power output end is connected to the second annular sub-housing to drive the second annular sub-housing to move towards or away from the annular base. Thus, by driving the first annular sub-housing to move through the first driving member and by driving the second annular sub-housing to move through the second driving member, the telescopic movement of the housing can be achieved.

[0031] Specifically, the first antenna element 120 can be fixedly connected to the first annular sub-shell and coaxially arranged with the first antenna element 120 and the first annular sub-shell. At the same time, the second antenna element 130 can be fixedly connected to the second annular sub-shell and coaxially arranged with the second antenna element 130 and the second annular sub-shell. In this way, when the first annular sub-shell moves toward or away from the annular base, it can drive the first antenna element 120 to move synchronously; when the second annular sub-shell moves toward or away from the annular base, it can drive the second antenna element 130 to move synchronously, so as to realize the switching between the second antenna element 130 and the first antenna element 120 between the first state and the second state.

[0032] In another embodiment of this disclosure, the housing includes a first annular sub-housing, a second annular sub-housing, and a telescopic component. The first and second annular sub-housings are coaxially arranged, and the telescopic component is disposed between the first and second annular sub-housings. The telescopic component includes a first telescopic end and a second telescopic end. During the telescopic movement of the telescopic component, the first and second telescopic ends move towards each other or in opposite directions. The first telescopic end can be connected to the first annular sub-housing, and the second telescopic end can be connected to the second annular sub-housing. Thus, during the telescopic movement of the telescopic component, it can drive the first and second annular sub-housings to move towards each other or in opposite directions, thereby achieving the telescopic movement of the housing. The first antenna element 120 can be fixedly connected to the first annular sub-shell and coaxially arranged with the first antenna element 120 and the first annular sub-shell. At the same time, the second antenna element 130 can be fixedly connected to the second annular sub-shell and coaxially arranged with the second antenna element 130 and the second annular sub-shell. In this way, when the first annular sub-shell and the second annular sub-shell move in opposite directions, the first antenna element 120 and the second antenna element 130 can be driven to move in opposite directions, so as to realize the switching of the second antenna element 130 and the first antenna element 120 between the first state and the second state.

[0033] In this embodiment, by setting the housing as a retractable housing and connecting the first antenna vibrator 120 and the second antenna vibrator 130 to the housing 150 respectively, the retractable housing can drive the first antenna vibrator 120 and the second antenna vibrator 130 to move in opposite directions or towards each other, thereby realizing the switching of the second antenna vibrator 130 and the first antenna vibrator 120 between the first state and the second state.

[0034] Optionally, the watch further includes a housing 150, a circuit board 110, a display screen 160, and a drive assembly 140. The housing 150 is connected to the display screen 160, and the housing 150 and the display screen 160 enclose a cavity. The circuit board 110 and the drive assembly 140 are disposed within the cavity, and the first antenna vibrator 120 and the second antenna vibrator 130 are located outside the cavity.

[0035] The first antenna element 120 and the second antenna element 130 are respectively arranged around the display screen 160, and the first antenna element 120 is connected to the housing 150, while the second antenna element 130 is located on the side of the first antenna element 120 that is away from the housing 150.

[0036] Please see Figure 1 and Figure 4 The housing 150 may include a frame 151 and a lower cover 152, wherein the lower cover 152, the frame 151, and the display screen 160 may be connected in sequence. See also... Figure 1 The frame 151 and the lower cover 152 can be fixedly connected by screws 250. The first antenna element 120 and the second antenna element 130 can be made into two annular decorative parts on the outside of the display screen 160 to improve the overall aesthetics of the watch.

[0037] It is understandable that during the process of the drive component 140 driving the second antenna vibrator 130 away from the first antenna vibrator 120, the second antenna vibrator 130 may protrude relative to the display screen 160, at which time the overall thickness of the watch increases.

[0038] Specifically, the drive assembly 140 can be any drive component capable of outputting reciprocating linear motion as described in the above embodiments, such as a telescopic motor, a crank-slider drive mechanism, or a lead screw-nut drive mechanism. When the drive assembly 140 is a telescopic motor, the telescopic end of the telescopic motor can be fixedly connected to the second antenna vibrator 130, so that the telescopic motor drives the second antenna vibrator 130 to move toward or away from the first antenna vibrator 120. Correspondingly, when the drive assembly 140 is a crank-slider drive mechanism, the slide of the crank-slider drive mechanism can be fixedly connected to the second antenna vibrator 130, so that during the reciprocating sliding of the slide, the second antenna vibrator 130 can be driven to move toward or away from the first antenna vibrator 120. When the drive assembly 140 is a lead screw-nut drive mechanism, the nut can be fixedly connected to the second antenna vibrator 130, so that during the reciprocating motion of the nut along the lead screw, the second antenna vibrator 130 can be driven to move toward or away from the first antenna vibrator 120.

[0039] In this embodiment, since the first antenna element 120 and the second antenna element 130 are located outside the accommodating cavity, the problem of antenna elements occupying internal space of the watch can be avoided. Furthermore, since the first antenna element 120 and the second antenna element 130 are respectively arranged around the display screen 160, the first antenna element 120 and the second antenna element 130 can be made into edge decorative parts of the display screen 160 to improve the watch's aesthetics. At the same time, since the second antenna element 130 is located on the outermost side of the watch, sufficient movement space for the second antenna element 130 can be ensured.

[0040] Optionally, the drive assembly 140 includes a transmission component 170 and a drive module. The drive module is connected to the second antenna vibrator 130 through the transmission component 170, and the transmission component 170 is used to convert the rotational motion output by the drive module into linear motion, so as to drive the second antenna vibrator 130 to move toward or away from the first antenna vibrator 120.

[0041] Specifically, the transmission component 170 can move linearly along a direction parallel to the axis of the second antenna element 130, so as to drive the second antenna element 130 to move toward or away from the first antenna element 120.

[0042] The structure of the aforementioned transmission component 170 can be determined according to the type of motion output by the drive module. For example, when the drive assembly 140 is a lead screw and nut drive mechanism, the transmission component 170 can be the nut in the lead screw and nut drive mechanism, which can convert the rotational motion of the lead screw into linear motion along the lead screw. In this case, the drive module can include a lead screw and a drive motor. Correspondingly, when the drive assembly 140 is a crank and slider drive mechanism, the transmission component 170 can be the slider in the crank and slider drive mechanism, which can convert the rotational motion of the crank in the crank and slider drive mechanism into reciprocating linear motion. In this case, the drive module can include a crank and a drive motor for driving the crank to rotate.

[0043] In this embodiment, the rotational motion output by the drive module is converted into linear motion based on the transmission component 170, thereby realizing the process of driving the second antenna vibrator 130 to move toward or away from the first antenna vibrator 120.

[0044] Optionally, the transmission component 170 includes a push rod body 171 and a strip-shaped ring-shaped connecting body 172. The first end of the push rod body 171 is fixedly connected to the connecting body 172, and the second end of the push rod body 171 is fixedly connected to the second antenna vibrator 130. The extension direction of the push rod body 171 is perpendicular to the extension direction of the connecting body 172, and the push rod body 171 is parallel to the axis of the second antenna vibrator 130.

[0045] The drive module includes a drive component 180, a transmission module, and a rotating wheel 190. The drive component 180 is connected to the rotating wheel 190 via the transmission module. The rotating wheel 190 has an actuating part 192 at an eccentric position. The actuating part 192 passes through the ring of the connecting body 172 and is slidably connected to the connecting body 172.

[0046] During the process of the drive member 180 driving the rotating wheel 190 to rotate, the transmission member 170 moves linearly along the extension direction of the push rod body 171.

[0047] The drive component 180 can be various types of drive motors, and the transmission module can be a module formed by combining various common transmission components, such as a gear transmission module or a transmission module formed by other transmission components.

[0048] Please see Figure 7 The push rod body 171 can be rod-shaped, and the connecting body 172 can be ring-shaped. The first end of the push rod body 171 is connected to the middle position of the connecting body 172 along its length. The push rod body 171 and the connecting body 172 can be integrally formed. The transmission component 170 can be made of insulating material to prevent the transmission component 170 from conducting the first antenna vibrator 120 and the second antenna vibrator 130.

[0049] Please see Figure 2 During the process of the drive module driving the rotating wheel 190 to rotate, the actuating part 192 on the rotating wheel 190 rotates around the axis of the rotating wheel 190. At this time, the actuating part 192 slides in the connecting body 172 on one hand, and on the other hand, the actuating part 192 can drive the connecting body 172 to make a lifting and lowering motion, thereby realizing the lifting and lowering motion of the transmission component 170. The upper end of the transmission component 170 is fixedly connected to the second antenna vibrator 130. Therefore, the second antenna vibrator 130 will also follow the transmission component 170 to make a lifting and lowering motion, so as to realize the function of moving towards or away from the first antenna vibrator 120.

[0050] Please see Figure 1 and Figure 3Specifically, the second antenna vibrator 130 and the transmission component 170 can be fixedly connected by a nut 260. The nut 260 can be embedded in the second antenna vibrator 130. The outer side wall of the second end of the push rod body 171 can be provided with an external thread that matches the nut 260, and the second end of the push rod body 171 is threadedly connected to the nut 260.

[0051] In this embodiment, by providing a deflector 192 at an eccentric position on the rotating wheel 190, and by having the deflector 192 pass through the ring of the connecting body 172 and slide in connection with the connecting body 172, the deflector 192 can drive the transmission member 170 to make linear motion during the rotation of the rotating wheel 190, thereby realizing the process of converting the rotational motion output by the drive module into linear motion.

[0052] Optionally, the first antenna vibrator 120 is provided with a first guide hole 200, and the push rod body 171 passes through the first guide hole 200.

[0053] The cross-sectional shape of the first guide hole 200 can be the same as the cross-sectional shape of the push rod body 171, and the cross-sectional size of the first guide hole 200 can be the same as the cross-sectional size of the push rod body 171, or the cross-sectional size of the first guide hole 200 can be slightly larger than the cross-sectional size of the push rod body 171, so as to ensure that the push rod body 171 can perform telescopic movement relative to the first guide hole 200.

[0054] It is understandable that the position of the first antenna vibrator 120 can remain unchanged during the movement of the push rod body 171 relative to the first guide hole 200.

[0055] In this embodiment, by having the push rod body 171 pass through the first guide hole 200, under the guidance of the first guide hole 200, the transmission member 170 can only move linearly along the first guide hole 200 under the drive of the actuating part 192, thereby improving the stability of the movement of the transmission member 170.

[0056] Optionally, the drive assembly 140 includes two transmission members 170, and the drive module includes two rotating wheels 190 corresponding to the two transmission members 170. The drive member 180 is connected to the two rotating wheels 190 respectively through the transmission module, and the actuating part 192 of the rotating wheel 190 is slidably connected to the connecting body 172 of the corresponding transmission member 170.

[0057] The two transmission components 170 are arranged in parallel. The second antenna element 130 includes two connection positions that correspond one-to-one with the two transmission components 170. The second end of the transmission component 170 is fixedly connected to the corresponding connection position, and the line connecting the two connection positions intersects the axis of the second antenna element 130.

[0058] Please see Figure 2 During the process of the drive module driving the rotating wheel 190 to rotate, the actuating part 192 on the two rotating wheels 190 can drive their respective corresponding transmission components 170 to move synchronously up and down. The upper ends of the two transmission components 170 are fixedly connected to the second antenna vibrator 130. Therefore, the second antenna vibrator 130 will also follow the two transmission components 170 to move up and down, so as to realize the function of moving towards or away from the first antenna vibrator 120.

[0059] In this embodiment, by including two transmission members 170 in the drive assembly 140, the two transmission members 170 can synchronously drive the second antenna vibrator 130 toward or away from the first antenna vibrator 120 from both sides, thereby improving the stability of the movement of the second antenna vibrator 130.

[0060] Optionally, the transmission module includes a first gear 210, a second gear 220, and a transmission shaft 230. The drive unit 180 is fixedly connected to the circuit board 110, and the transmission shaft 230 is rotatably connected to the circuit board 110. The first gear 210 is fixedly sleeved on the output shaft of the drive unit 180, and the second gear 220 is fixedly sleeved on the transmission shaft 230, with the first gear 210 and the second gear 220 meshing. The two rotating wheels 190 are respectively fixedly sleeved on the output shaft.

[0061] Please see Figure 2The drive shaft 230 can be mounted on the circuit board 110 via two bearing seats 240. Two rotating wheels 190 can be located on opposite sides of the circuit board 110. The first gear 210 and the second gear 220 can be located on the same side of the circuit board 110. The drive unit 180 is a drive motor; during the rotation of the output shaft of the drive unit 180, it drives the first gear 210 to rotate synchronously. The first gear 210 drives the drive shaft 230 to rotate forward or backward via the second gear 220. When the actuating part 192 of the rotating wheel 190 is at its lowest point, the distance between the first antenna element 120 and the second antenna element 130 is minimal. At this time, the first antenna element 120 and the second antenna element 130 can be in close contact to jointly serve as the radiators of the antenna. Furthermore, when the actuating part 192 of the rotating wheel 190 is at its lowest point, there can also be a certain gap between the first antenna element 120 and the second antenna element 130. This can be achieved by structurally designing the first antenna element 120 and the second antenna element 130 so that they have the same phase. In this way, when there is a certain gap between the first antenna element 120 and the second antenna element 130, the first antenna element 120 and the second antenna element 130 can also work together.

[0062] Correspondingly, when the actuation part 192 of the rotating wheel 190 is at its highest point, the distance between the first antenna element 120 and the second antenna element 130 is at its maximum. At this time, the first antenna element 120 and the second antenna element 130 can together form a circularly polarized Yagi antenna.

[0063] In this embodiment, by including a first gear 210, a second gear 220 and a transmission shaft 230 in the transmission module, the motion of the driving member 180 is transmitted to the rotating wheel 190, thereby driving the rotating wheel 190 to rotate.

[0064] Optionally, the rotating wheel 190 includes a wheel body 191 and an actuating rod disposed at an eccentric position on the wheel body 191. The actuating rod is parallel to the axis of the wheel body 191 and forms the actuating part 192. One end of the actuating rod away from the wheel body 191 is disposed at a limiting part, and the connecting body 172 is limited between the wheel body 191 and the limiting part.

[0065] The actuating part 192 may be a pin perpendicular to the wheel body 191. It is understood that the limiting part may be a limiting plate, which can limit the connecting body 172 to prevent it from detaching from one end of the limiting part.

[0066] In this embodiment, by limiting the connector 172 between the wheel body 191 and the limiting part, the connector 172 can be prevented from disengaging from the actuating part 192, thereby improving the stability of the connection between the connector 172 and the actuating part 192.

[0067] Optionally, the housing 150 includes an annular support portion 1512 opposite to the first antenna vibrator 120, the annular support portion 1512 having a second guide hole 1511 opposite to the first guide hole 200, and the push rod body 171 passing through the second guide hole 1511.

[0068] Please see Figure 1 and Figure 3 Specifically, the frame 151 may include the annular support portion 1512, which is located at one end of the frame 151 near the display screen 160. The annular support portion 1512 can be used to support the first antenna element 120.

[0069] The cross-sectional shape of the second guide hole 1511 can be the same as the cross-sectional shape of the push rod body 171, and the cross-sectional size of the second guide hole 1511 can be the same as the cross-sectional size of the push rod body 171, or the cross-sectional size of the second guide hole 1511 can be slightly larger than the cross-sectional size of the push rod body 171, so as to ensure that the push rod body 171 can perform telescopic movement relative to the second guide hole 1511.

[0070] It is understood that the position of the annular support portion 1512 remains unchanged during the movement of the push rod body 171 relative to the second guide hole 1511.

[0071] In this embodiment, by having the push rod body 171 pass through both the first guide hole 200 and the second guide hole 1511, under the guidance of the first guide hole 200 and the second guide hole 1511, the transmission member 170 can only move linearly along the first guide hole 200 and the second guide hole 1511 under the drive of the actuating part 192, thereby improving the stability of the movement of the transmission member 170.

[0072] Optionally, the first antenna element 120 is bonded to the annular support portion 1512.

[0073] In this embodiment, by bonding the first antenna vibrator 120 to the annular support portion 1512, the friction between the transmission member 170 and the first guide hole 200 can be avoided from driving the first antenna vibrator 120 to move during the movement of the transmission member 170 relative to the first guide hole 200.

[0074] Optionally, the travel range of the second antenna element 130 includes a first extreme position and a second extreme position;

[0075] When the second antenna element 130 is in the first extreme position, the first antenna element 120 and the second antenna element 130 are spaced apart, and the first antenna element 120 and the second antenna element 130 form a circularly polarized Yagi antenna.

[0076] When the second antenna element 130 is in the second extreme position, the first antenna element 120 and the second antenna element 130 are in contact to jointly form the radiator of the antenna.

[0077] The first extreme position can be the position where the actuating part 192 moves to its highest point, and the second extreme position can be the position where the actuating part 192 moves to its lowest point. The actuating part 192 can switch between the first extreme position and the second extreme position once every 180° rotation. For example, please refer to... Figure 7 This is a schematic diagram of the motion state of the second antenna element 130 as it moves from the second extreme position to the first extreme position.

[0078] Specifically, when satellite communication is not in operation, the toggle unit 192 can be located at its lowest point, and the first antenna element 120 and the second antenna element 130 are in contact. At this time, by reasonably designing the size and spacing between the two, their phases are made the same. When their phases are the same, the first antenna element 120 and the second antenna element 130 cannot excite the coupled modes in the operating frequency band of the radio frequency system that they can support. In this way, the efficiency of the element radiation will not be lost, and the radio frequency communication needs of the user's conventional smart terminal can be met.

[0079] When satellite communication is in operation, the toggle unit 192 can be at its highest point. The transmission component 170 pushes the second antenna element 130 to its highest position, maximizing the separation between the first antenna element 120 and the second antenna element 130, achieving the working state. At this point, it perfectly meets the requirements of the Yagi antenna structure under the satellite communication frequency band. Due to the low axial ratio circular polarization design of the two elements, a high directional radiation pattern with the dial normal pointing upwards can be achieved. Users can obtain high satellite communication radiation performance by using the dial upwards according to conventional usage habits.

[0080] In this embodiment, by enabling the second antenna oscillator 130 to have two operating states, the user can control the second antenna oscillator 130 to switch between the two operating states via software according to whether they have communication needs with the satellite, thereby improving the communication quality between the watch antenna and the satellite.

[0081] It is understood that, in addition to cooperating with the transmission component 170 through the actuating part 192 of the rotating wheel 190, the rotational motion output by the drive module can be converted into linear motion. In other embodiments of this disclosure, a series of moving parts such as cranks, slides, and lead screws and nuts can also be used to achieve the above-mentioned process of "converting the rotational motion output by the drive module into linear motion".

[0082] When a crank-slider mechanism is used to realize the above-mentioned process of "converting the rotational motion output by the drive module into linear motion", the drive component 180 can be connected to the crank to drive the drive to rotate. At the same time, the slide bar can be connected to the second antenna vibrator 130 to drive the second antenna vibrator 130 to perform reciprocating linear motion.

[0083] Accordingly, when the screw and nut mechanism is used to realize the above-mentioned process of "converting the rotational motion output by the drive module into linear motion", the drive component 180 can be connected to the screw to drive the screw to rotate around its own axis. At the same time, the thread sleeved on the screw is connected to the second antenna vibrator 130 to drive the second antenna vibrator 130 to perform reciprocating linear motion.

[0084] In another embodiment of this disclosure, in addition to the second antenna element 130 being movable relative to the first antenna element 120, the first antenna element 120 can also move toward or away from the second antenna element 130. For example, a telescopic component can be added within the accommodating cavity and connected to the first antenna element 120 to enable the first antenna element 120 to move toward or away from the second antenna element 130. The telescopic component can be a telescopic motor or other telescopic component.
