At present, with the development of wearable devices, satellite positioning and motion trajectory recording have become one of the necessary functions of wearable devices, and in order to achieve the purposes of positioning and trajectory recording, a satellite positioning system is an indispensable structure of electronic devices. Taking a GPS satellite positioning system as an example, the civil frequency band of the GPS satellite positioning system mainly includes an L1 frequency band and an L5 frequency band, the central operating frequency of the L1 frequency band is about 1.575GHz, and the central operating frequency of the L5 frequency band is about 1.176 GHz.

The wearable device 10 may implement the first radiator 120 through the housing assembly 100 and form a first antenna, and the second radiator 200 may be disposed on the housing assembly 100 to form a second antenna different from the first antenna. The first radiator 120 and the second radiator 200 are coupled to the feeding portion 301 of the first circuit board 300 for feeding, so that the first antenna and the second antenna are integrated in the wearable device 10 through single feeding, and the second radiator 200 and the first radiator 120 are arranged in an insulating manner, which can meet the isolation requirement. Therefore, the wearable device 10 can effectively reduce the isolation requirement, so that the internal elements of the wearable device 10 can be flexibly arranged, and the arrangement difficulty is reduced.

It will be appreciated that reducing the isolation requirements also facilitates reducing the limited space occupied by the isolation structure within the wearable device 10, which facilitates miniaturization of the wearable device 10 as compared to existing wearable devices 10. Alternatively, if the internal spaces are equal, the performance of the wearable device 10 can be improved by utilizing the extra space to improve the performance of other components (for example, the battery module 500 is increased in size to improve the cruising ability of the wearable device 10, and for example, a dual-band circular polarization antenna is integrated to improve the positioning performance of the wearable device 10). Alternatively, if the internal space is the same, other components are integrated by using the extra space to expand the function of the wearable device 10.

It should be noted that the housing assembly 100 may be implemented in various ways, and may form the receiving cavity 110 and integrate the first radiator 120.

As shown in fig. 2 to 3, in some embodiments, the display screen module 400 is disposed on the housing assembly 100, for example, the display screen module 400 is disposed in an opening of the housing assembly 100, and can close the accommodating cavity 110.

In some embodiments, the second radiator 200 is disposed between the display screen module 400 and the first radiator 120. Thus, the second radiator 200 can be disposed far away from the body of the user, so as to avoid interference of the human body to the signal, which is beneficial to improving the radiation performance of the second antenna.

In some embodiments, when the wearable device 10 is used as a wrist-worn device, the wrist band body of the wrist band 11 can be used as a compression band in a blood pressure measurement process, the change of the radial artery of the wrist drives the air pressure in the air cavity to change, the air pressure change can be detected by the air pressure detection element in the air cavity and fed back to the main board, and then the blood pressure value of the wearer can be obtained through the main board calculation.

In the application, the first radiator and the second radiator are coupled with the feed portion for feeding, so that the feed portion is shared. The feeding portion may include a feeding point, a feeding terminal, or a feeding line, but the present application is not limited thereto. In addition, the first circuit board further comprises at least one grounding part, and the first radiator and the second radiator are coupled with the at least one grounding part. In one example, the first circuit board includes two ground portions coupled to the first radiator and the second radiator, respectively. In another example, the first circuit board includes a ground coupled to both the first radiator and the second radiator.

In some embodiments, the second radiator is electromagnetically coupled to the first radiator, and the second radiator may be coupled to feed power to the second radiator by adjusting a distance between the second radiator and the first radiator, thereby generating additional resonance. In this case, as an example, the second radiator may be coupled to the feeding portion and the grounding portion on the first circuit board through the first radiator, instead of being connected to the feeding portion and the grounding portion, that is, the first radiator and the second radiator are coupled to the same feeding portion and the same grounding portion on the first circuit board. As another example, the second radiator may be connected to only the ground portion, not the feeding portion, so that the second radiator may be electrically connected to the ground portion on the first circuit board and coupled to feed through the feeding portion on the first circuit board. That is, the first radiator and the second radiator are coupled to the same feed on the first circuit board and to the same or different ground on the first circuit board.

In some embodiments, the second radiator and the first radiator are electrically connected to the same feeding portion on the first circuit board, and the grounding portions of the second radiator and the first radiator are electrically connected to the same or different grounding portions on the first circuit board, which is not limited herein.

In this way, the first radiator 120 is grounded to adjust the radiation performance.

The implementation manner of "the first radiator 120 is grounded to the first ground portion 302" may include, but is not limited to, a coupled ground manner such as a resistive ground (including a conductive structure for grounding), a capacitive ground, and an inductive ground.

Based on any of the above embodiments, in some embodiments, the wearable device 10 further comprises an adjusting unit for adjusting an operating frequency of at least one of the first antenna and the second antenna. As an example, as shown in fig. 4, the wearable device 10 further includes a first adjusting unit 600 for adjusting an operating frequency of the first antenna, and the first radiator 120 is coupled to the first ground 302 through the first adjusting unit 600. So, the first antenna of wearable equipment 10 of this application can independently be adjusted, is used for adjusting the operating frequency of first antenna through first regulating unit 600, can adjust the resonance of first antenna in a flexible way, is favorable to promoting the antenna performance on the less wearing equipment of volume, is convenient for be the circular polarization antenna with first antenna timing, and then can promote wearable equipment 10's location performance.

The first adjusting unit 600 includes at least one of a resistor, an inductor, a capacitor module, and the like. For the first radiator 120 with an effective circumference of one wavelength, in the embodiment of the present application, the first radiator 120 is directly fed, and the inductor and/or the capacitor are used to effectively pull the generated current, so that a rotating current field rotating in a single direction is formed inside the first radiator 120, and thus, a circular polarized wave can be implemented.

Further, in some embodiments, the first adjusting unit 600 includes a capacitor module 610, and the first radiator 120 is electrically connected to the first ground portion 302 through at least one capacitor module 610. In this way, the first radiator 120 is grounded through the at least one capacitor module 610, and the capacitor module 610 is used to pull the current generated by the first radiator 120 to form a rotating annular current, so as to form a circularly polarized wave, so that the first antenna is a circularly polarized antenna, and the positioning performance of the wearable device 10 can be improved.

According to the circular polarization antenna structure, the circular polarization antenna form of the equipment can be achieved, and therefore positioning is more accurate when the satellite positioning function is achieved. And through the electric capacity ground connection to first radiator 120, simplified circular polarized antenna's structure and cost greatly, it realizes on the less equipment in the isovolumetric space of wrist-watch to change into more easily. In addition, the effective electrical length of the antenna structure can be reduced through capacitive grounding, so that a higher working frequency can be realized by using a larger-size antenna structure, and more possibilities are provided for the design of a circularly polarized antenna.

As shown in fig. 4 or 5, in the above embodiment, the first radiator 120 is directly fed with power, and the capacitor module 610 is grounded to draw current generated by the first radiator 120, so as to implement circular polarization.

Further, in fig. 4 and 5, the wearable device 10 further includes a first conductive piece 710, and the first radiator 120 is conductively coupled to the feeding portion 301 through the first conductive piece 710. Thus, the first conductive member 710 allows the distance between the first radiator 120 and the first circuit board 300 to be flexibly adjusted.

It should be noted that specific implementations of the "first conductive member 710" include, but are not limited to, a conductive wire, a conductive body, a conductive strip, etc.

Further, in fig. 4 and 5, the second radiator 200 is electromagnetically coupled to the first radiator 120. In this way, the first radiator 120 is grounded through the first conductive member 710, and it is also convenient to adjust the distance (distance is equivalent to capacitance) between the second radiator 200 and the first radiator 120, so that additional resonance is generated by coupling and feeding the second radiator 200 to obtain a desired operating frequency.

It can be understood that after the second radiator 200 and the first radiator 120 are manufactured, the manufacturing error and the assembly error can be calibrated by adjusting the distance between the second radiator 200 and the first radiator 120, so as to adjust the operating frequency of the second antenna and ensure the radiation performance of the second antenna.

In addition, as shown in fig. 5, in some embodiments, the first circuit board 300 further includes a second ground portion 303, and the second radiator 200 is electromagnetically coupled to the first radiator 120 and is in ground connection with the second ground portion 303. Thus, by adjusting the distance between the second radiator 200 and the first radiator 120, additional resonance can be generated by coupling and feeding the second radiator 200, and the second radiator 200 and the second ground portion 303 are in ground connection, so that the resonant frequency of the additional resonance generated by the second radiator 200 can be adjusted, the resonance can meet the required use frequency, and the radiation performance of the second antenna can be improved.

As shown in fig. 6, in other embodiments, the first circuit board 300 includes a first ground portion 302 and a second ground portion 303, the first ground portion 302 and the second ground portion 303 are disposed at two sides of the feeding portion 301, wherein the first radiator 120 is coupled to the first ground portion 302, the second radiator 200 is coupled to the second ground portion 303, and the first radiator 120 and the first ground portion 302 are in ground connection, which is beneficial to independently adjusting resonance of the first antenna and improving radiation performance of the first antenna; the second radiator 200 and the second grounding portion 303 are grounded and matched, so that resonance of the second antenna can be independently adjusted, the radiation performance of the second antenna can be improved, and two circularly polarized antennas with different frequency bands can be more easily integrated into the wearable device 10.

Furthermore, in some embodiments, as shown in fig. 6, the wearable device 10 further includes a second conductive member 720, and the first radiator 120 and the second radiator 200 are conductively coupled to the feed 301 through the second conductive member 720. In this way, the second conductive member 720 is utilized to flexibly adjust the distance between the first radiator 120 and the first circuit board 300 and the second radiator 200.

It should be noted that specific implementations of the "second conductive member 720" include, but are not limited to, a conductive wire, a conductive body, a conductive strip, etc. Alternatively, the second conductive member 720 may electrically connect the first and second radiators 120 and 200 to the feeding portion 301 by multi-segment conductive line matching.

On the basis of any of the above embodiments in which the second radiator 200 is in ground-connection with the second ground portion 303, as shown in fig. 6, in some embodiments, the wearable device 10 further includes a second adjusting unit 800 for adjusting an operating frequency of the second antenna, and the second radiator 200 is in ground-connection with the second ground portion 303 through the second adjusting unit 800.

The second adjusting unit 800 includes at least one of a resistor, an inductor, a capacitor, and the like. For the second radiator 200 having an effective circumference of one wavelength, in the embodiment of the present application, the second radiator 200 is directly fed, and the inductor and/or the capacitor are/is used to effectively draw the generated current, so that a rotating current field rotating in a single direction is formed inside the second radiator 200, and then the circular polarized wave can be implemented.

Further, in some embodiments, the second adjusting unit 800 includes an inductance module 810, and the second radiator 200 is grounded to the second ground 303 through at least one inductance module 810. In this way, the second radiator 200 is grounded through the at least one inductance module 810, and the inductance module 810 is used for drawing the current generated by the second radiator 200 to form a rotating annular current, so as to form a circularly polarized wave, so that the second antenna is a circularly polarized antenna, and the positioning performance of the wearable device 10 can be improved.

According to the circular polarization antenna structure, the circular polarization antenna form of the equipment can be achieved, and therefore positioning is more accurate when the satellite positioning function is achieved. And through the inductance grounding of the second radiator 200, the structure and the cost of the circularly polarized antenna are greatly simplified, and the circularly polarized antenna is easier to realize on equipment with a smaller volume space of the watch. In addition, the effective electrical length of the antenna structure can be reduced through inductive grounding, so that a higher working frequency can be realized by using a larger-size antenna structure, and more possibilities are provided for the design of a circularly polarized antenna.

As shown in fig. 8, in the above embodiment, the second radiator 200 is directly fed with power, and the inductance module 810 is grounded to draw current generated by the second radiator 200, so as to implement circular polarization. The first radiator 120 also feeds directly, and the capacitor module 610 is grounded to draw current generated by the first radiator 120, so that integration of the dual circularly polarized antenna in the wearable device 10 is realized, and the positioning performance of the wearable device 10 is improved.

It should be noted that the first adjusting unit 600 and the second adjusting unit 800 may include a conductor in addition to a capacitor or an inductor, and the first circuit board 300 is flexibly connected by using the conductor.

In some embodiments, the first radiator 120 is electrically connected to the rf unit on the first circuit board 300 to implement power feeding.

In addition to the above embodiments, as shown in fig. 7, in some embodiments, the first circuit board 300 includes a substrate 313, a ground layer 312 and a feeding strip 311, the ground layer 312 and the feeding strip 311 are disposed on the substrate 313 in an insulating manner, the first ground portion 302 and the second ground portion 303 are disposed at different positions of the ground layer 312, and the feeding strip 311 is disposed with the feeding portion 301. Therefore, by using the ground layer 312, it is convenient to form a plurality of ground portions on the first circuit board 300, and then the working frequency of the first antenna can be adjusted by the positions of different first ground portions 302, so that the resonance of the first antenna can be flexibly adjusted, which is beneficial to improving the antenna performance on the wearable device with a small size, and is convenient to adjust the first antenna into a circularly polarized antenna, thereby improving the positioning performance of the wearable device 10. Similarly, the operating frequency of the second antenna can be adjusted through the positions of the different second grounding portions 303, the resonance of the second antenna can be flexibly adjusted, the antenna performance can be improved on the wearable device with a small size, the second antenna can be conveniently adjusted to be a circularly polarized antenna, and the positioning performance of the wearable device 10 can be improved. Moreover, the first antenna and the second antenna can be independently adjusted, and the position of the resonance point can be flexibly adjusted in the limited internal space of the wearable device 10.

The number of layers of the "ground layer 312" may be one or more, and the antenna may be grounded. Alternatively, the ground layer 312 is a metal shielding layer, and may be a copper foil, an aluminum foil, a magnesium foil, or the like.

In addition, the first connector portion and the second ground portion 303 may be pad portions of the ground layer 312, such as pads.

It should be noted that there may be one or more feeding strips 311, and the feeding function of the antenna may be implemented. Alternatively, the metal line layer may be obtained by etching a copper foil, an aluminum foil, a magnesium foil, or the like by a pattern development technique.

In addition, the feeding strip 311 and the ground layer 312 may be disposed on the same layer, or may be disposed on different layers, which is not limited herein.

Based on any of the above embodiments, as shown in fig. 7 in combination with fig. 4, fig. 5 or fig. 6, in some embodiments, the first antenna is a circularly polarized antenna and operates in a GPS L1 resonant frequency band; the second antenna is a circularly polarized antenna and operates in the resonant frequency band of GPS L5. Therefore, by using the feeding mode and the grounding mode of the present application, the wearable device 10 integrates the dual-band circularly polarized antenna in a limited space, and the positioning performance of the wearable device 10 is improved.

In some embodiments, the second radiator 200 has a closed loop shape. In this way, it is convenient to set the second antenna as a circularly polarized antenna.

Further, the first radiator 120 also has a closed loop shape. In this way, it is convenient to set the first antenna as a circularly polarized antenna. In conjunction with the foregoing embodiments, as shown in fig. 8, two circularly polarized antennas of different frequency bands may be integrated into the wearable device 10. For example, the first antenna is a circularly polarized antenna GPS L1, and its central operating frequency is about 1.176 GHz; the second antenna is a circularly polarized antenna GPS L5, and the central working frequency is about 1.575 GHz.

It should be noted that the circularly polarized antenna can be divided into Left-Hand Circular Polarization (LHCP) and Right-Hand Circular Polarization (RHCP). Taking a satellite positioning antenna as an example, the main global satellite navigation positioning systems include GPS, beidou, GLONASS and galileo, and the civil satellite positioning of these positioning systems all adopt a right-hand circular polarization form.

For implementing a circular polarized antenna using the annular first radiator 120, the wavelength of the central operating frequency of the first radiator 120 is equal to the effective circumference of the first radiator 120, and thus, when designing the antenna, the effective circumference of the first radiator 120 may be set to be equal to one wavelength of the desired operating frequency.

Similarly, for implementing a circular polarized antenna using the second radiator 200 having a ring shape, the wavelength of the central operating frequency of the second radiator 200 is equal to the effective circumference of the second radiator 200, and therefore, when designing the antenna, the effective circumference of the second radiator 200 may be set to be equal to one wavelength of the desired operating frequency.

In addition, it is understood that the "effective circumference" described herein does not necessarily refer to the "physical circumference" of the first radiator 120 or the second radiator 200 around the circumference. In free space, the physical circumference of the first radiator 120 or the second radiator 200 around one circle is the effective circumference of the first radiator 120. However, in the mounting structure, the mounting structure around the first radiator 120 or the second radiator 200 and the material around the mounting structure will increase the effective circumference of the first radiator 120 or the second radiator 200, i.e., will decrease the resonant frequency band of the first radiator 120 or the second radiator 200. For example, when the first radiator 120 is assembled with a plastic material (e.g., a plastic bracket or a nano-injection molding material), the material increases the effective circumference of the first radiator 120. For another example, the screen assembly near the second radiator 200 may also have an effect of increasing the effective perimeter of the second radiator 200, such as a glass cover of the screen assembly.

Based on any of the above embodiments, as shown in fig. 9, in some embodiments, the second radiator 200 includes a metal ring 210 and at least one adjusting element 220 connected to the metal ring 210, and the at least one adjusting element 220 is used for adjusting an effective radiation length of the second radiator 200. Therefore, the adjusting element 220 is added to the metal ring 210 to offset all or part of capacitive reactance of the antenna element at this point, so as to increase a current path, achieve the purpose of adjusting the effective radiation length of the second radiator 200, and further achieve the purpose of adjusting the operating frequency of the second antenna, so as to meet the requirements of different types of product structures for integrating the antenna structure.

It should be noted that the material of the "adjusting element 220" includes metal, plastic, and other high dielectric constant materials with a dielectric constant greater than that in air, and can be fixed in series on the metal ring 210 by various means, so as to adjust the resonant frequency of the extra resonance generated by the metal ring, so that the resonance meets the required use frequency band.

The specific form of the adjusting element 220 further includes a capacitor or an inductor, etc., which can adjust the effective radiation length. For example, the inductive reactance of the inductor may cancel all or part of the capacitive reactance exhibited by the antenna element above this point, thereby increasing the antenna current below the inductive point

Furthermore, the adjustment element 220 may be located anywhere on the metal ring 210, or may be located away from the lossy element, such as the screen FPC, to avoid affecting antenna performance. For another example: at least one of 0 o 'clock position, 3 o' clock position, 6 o 'clock position, and 9 o' clock position in the bezel clock direction may be provided, but the specific position is not limited herein.

Based on any of the above embodiments, as shown in fig. 10 and 11, in some embodiments, the second radiator 200 is in a closed loop shape and includes a first metal 230 and a second metal 240 connected to the first metal 230, where at least a portion of the first metal 230 and at least a portion of the second metal 240 are located in different planes. Thus, the current path may be increased by bending and other deformation of at least a portion of the first metal element 230 and at least a portion of the second metal element 240 in different planes, for example, the first metal element extends along a plane parallel to the first radiator, and the second metal element may extend upward or downward from the plane of the first radiator, so as to achieve the purpose of adjusting the effective radiation length of the second radiator 200, and further achieve the purpose of adjusting the operating frequency of the second antenna, so as to meet the requirements of different types of product structures to integrate the antenna structure. That is, the second radiator 200 may implement frequency tuning by performing three-dimensional routing using a thickness space.

It should be noted that the "first metal part 230 and the second metal part 240 connected to the first metal part 230" may be added anywhere in the second radiator 200, or may be disposed at a position far away from the lossy device, for example, a position far away from the screen FPC, so as to avoid affecting the antenna performance. For another example, the clock signal may be set at least one of 0 o 'clock position, 3 o' clock position, 6 o 'clock position, and 9 o' clock position in the frame clock direction, but the specific position is not limited herein.

In addition, the first metal piece 230 and the second metal piece 240 connected to the first metal piece 230 may be formed in various patterns. For example, by winding around the insulating support 140, this action may increase the current path.

The first metal piece 230 is directly or indirectly connected to the second metal piece 240. For example, as shown in figure 11, the first metal element 230 is "square", so that they may be directly connected end to end. Or the first metal part 230 is in a first arc shape, the second metal part 240 is in a second arc shape, and the opening of the second arc shape is opposite to the opening of the first arc shape, so that the first metal part and the second metal part can be directly connected end to end.

In summary, the two frequency bands generated by the first antenna and the second antenna of the present application can be independently adjusted. The first antenna resonance can be flexibly adjusted by adjusting the positions of the first radiator and the first grounding part on the first current board and the value of the first adjusting unit connected with the first grounding part in series. The effective radiation length is adjusted through the positions of the first radiating body and the first grounding part on the first current plate, the value of the first adjusting unit connected with the first grounding part in series, the distance between the second radiating body and the first radiating body, the matching of the metal ring and the adjusting part and the matching of the first metal part and the second metal part, and the resonance of the second antenna can be flexibly adjusted. So in the limited inner space of wearable equipment, can adjust the position of resonance point in a flexible way, reduced relevant components and parts (like screen pack etc.) to the influence of antenna resonance position.

Based on any of the above embodiments, as shown in fig. 2 to 4, in some embodiments, the housing assembly 100 includes a metal middle frame 130 for forming the first radiator 120; the wearable device 10 further includes an insulating support 140, and the second radiator 200 is fixed to the metal middle frame 130 and is insulated from the metal middle frame 130 by the insulating support 140. In this way, the first radiator 120 is formed by the metal middle frame 130 made of a metal material, so that the volume space of the wearable device 10 can be fully utilized to meet the length requirement of the first antenna, thereby being beneficial to improving the radiation performance of the first antenna. The first antenna can be adjusted to be a circularly polarized antenna, so that the satellite signal strength received by the ground equipment can be improved by about 3dB under the condition that the antenna efficiency is equivalent; meanwhile, the anti-interference capability of a satellite positioning system of the receiving equipment can be enhanced in a complex environment, and more accurate positioning and movement tracks can be obtained.

The second radiator 200 can be integrated on the metal middle frame 130 through the insulating support 140, so that the length requirement of the second antenna can be met by fully utilizing the metal middle frame 130, and the radiation performance of the second antenna can be improved. The second antenna can be adjusted to be a circularly polarized antenna, so that the satellite signal strength received by the ground equipment can be improved by about 3dB under the condition of equivalent antenna efficiency; meanwhile, the anti-interference capability of a satellite positioning system of the receiving equipment can be enhanced under a complex environment, and further more accurate positioning and movement tracks can be obtained.

Alternatively, the housing assembly 100 may form the receiving cavity 110 by the back cover 150 cooperating with the metal middle frame 130.

It should be noted that the second radiator 200 and the first radiator 120 may be made of metal, so as to realize antenna radiation.

In some embodiments, the second radiator 200 is made of metal and can be used as an exterior decoration of a watch in consideration of the exterior design of the watch. For example, the second radiator 200 may be used as a face frame of the wearable device 10 to assemble the display screen module 400, and may have a decorative structure such as a scale, a pattern, a diamond, etc. thereon, so as to improve the appearance of the front surface of the watch. The first radiator 120 is a metal middle frame 130, which can be used as a bezel decoration of the watch.

As shown in fig. 12, in other embodiments, the housing assembly 100 includes an insulating middle frame 160, at least a portion of the first radiator 120 is embedded in the insulating middle frame 160, and the second radiator 200 is fixed on the insulating middle frame 160 and spaced apart from the first radiator 120; alternatively, the second radiator 200 is at least partially embedded in the sidewall of the receiving cavity 110. Thus, the first radiator 120 and the second radiator 200 can be arranged in an insulating manner through the insulating middle frame 160 without arranging an insulating layer, so that the consistency of the appearance of the device can be improved, and the structure of the device can be simplified to meet the design requirements of different product types.

In addition, the first radiator 120 and the second radiator 200 may be embedded in the insulating middle frame 160 by a secondary injection molding method, so that the assembly process is reduced, and the assembly efficiency of the wearable device 10 is improved.

In addition, the first radiator 120 and the second radiator 200 may be insulated from each other in various ways. In addition to the above, an insulating layer or the like may be disposed between the first radiator 120 and the second radiator 200.

Similarly, the first radiator 120 has a circular ring structure, and in other embodiments, the first radiator 120 may also have any other circular structure suitable for implementation, for example, a triangular ring, a diamond ring, a rectangular ring, a rounded rectangular ring, or another polygonal ring, which is not limited in this application.

In this embodiment of the application, two or more frequency bands corresponding to the first radiator and the second radiator may be independently adjusted, and the resonance of the first radiator may be flexibly adjusted by adjusting at least one of the positions of the first grounding end point and the first ground feeding end point of the metal frame and the PCB, and the parameters of the series element of the first grounding end point or the first ground feeding end point. And by adjusting at least one of the distance between the second radiator and the metal frame, the size of the second radiator, the position of the second grounding end point (if any) and the parameters of the serial element (if any) of the second grounding end point, the position of the resonance point can be flexibly adjusted within the limited structural range of the watch, and the influence of related components (such as a screen assembly and the like) on the resonance position of the antenna is reduced.

Therefore, the radiation performance of the antenna in other frequency bands can be balanced, and the radiation performance of the second antenna can be ensured. For example, the radiation performance of the first antenna is not influenced, and the cost is effectively reduced.

As an example, the first antenna is a communication antenna, and the second antenna is a positioning antenna, for example, the second radiator may implement a single-frequency or dual-frequency GPS antenna.

The second circuit board can be a flexible circuit board FPC or a Liquid Crystal Polymer (LCP) board. The second circuit board 900 feeds the second radiator 200 through the feeding portion 301 to generate resonance of the second antenna, and then radiates out through the generated electromagnetic waves.

It should be noted that the second radiator 200 on the second circuit board 900 has multiple feeding modes. The feed 301 and the second radiator 200 are connected by, for example, clips. Alternatively, the coupling of the second radiator 200 to the feed 301 is achieved using the electrical connector 910 and the stripline. In the example shown in fig. 14, the second radiator is an antenna branch, or may also be a closed metal ring, so as to implement a circular polarization antenna, which is not limited to this embodiment.

In addition, the second radiator 200 on the second circuit board 900 may also adjust the operating frequency of the second antenna by using the aforementioned adjusting element 220 and/or the second adjusting unit 800, so as to flexibly adjust the resonance of the second antenna, thereby facilitating the improvement of the antenna performance on the wearable device with a small size, facilitating the adjustment of the second antenna into a circularly polarized antenna, and further improving the positioning performance of the wearable device 10.
