The lengths of the first radiating branch 121 and the second radiating branch 122 are not limited herein, for example, the length of the first radiating branch 121 may be λ/4 or 3 λ/4 of an operating frequency band of the first antenna 120 when receiving and transmitting long term evolution LTE signals, or may be other lengths that meet the requirement of the first antenna 120 for receiving and transmitting signals.

The end of the first radiating branch 121 far from the second radiating branch 122 forms a radiating end, and the end of the second radiating branch 122 far from the first radiating branch 121 forms a radiating end, so that the distance between the radiating ends of the first radiating branch and the second radiating branch is increased as much as possible, the isolation between the first radiating branch and the second radiating branch is increased, and the mutual interference between the first radiating branch and the second radiating branch is reduced.

Referring to fig. 2, in the present embodiment, the second antenna 130 may also be a slot antenna having the same structure as the first antenna 120. Specifically, the second frame 112 and the middle frame plate 114 are spaced apart from each other to form a second gap 1162, the second frame 112 is provided with a second through gap 1161 penetrating through the second frame 112, and the second gap 1162 is communicated with the second through gap 1161 to form the second antenna 130 on the second frame 112.

The first and second parts are for convenience of description only and are not limiting; the slit width in the figure is only a schematic width and does not represent the actual slit width; and the slot lengths in the figures are only schematic lengths and do not represent actual slot lengths.

The second through gap 1161 is communicated with the second gap 1162 to form the second antenna 130 on the second frame 112, and the second antenna 130 is directly exposed, so that interference of internal electronic devices is avoided, and the strength of the second antenna 130 for transmitting and receiving signals is increased. In terms of process and cost, the second antenna 130 is formed on the metal frame, so that the process of additionally arranging a radiator inside the wearable electronic device 100 is reduced by forming the antenna, and the production cost of the wearable electronic device 100 is reduced.

In this embodiment, one end of the first antenna 120 faces one of the connection frames 113 to form a radiation end, one end of the second antenna 130 faces the other connection frame 113 to form a radiation end, when the first antenna 120 and the second antenna 130 transmit and receive signals, the radiation intensity of the two antennas at the radiation end is high, meanwhile, the radiation end of the first antenna 120 can radiate electromagnetic waves through the first through slot 1151, and the radiation end of the second antenna 130 can radiate electromagnetic waves through the second through slot 1161.

By separating the radiation end of the first antenna 120 and the radiation end of the second antenna 130 as far as possible, the isolation between the first antenna 120 and the second antenna 130 is increased, and thus the signal interference between the two can be reduced or avoided. The end of the first antenna 120 far from the radiation end of the first antenna 120 is grounded, the end of the second antenna 130 far from the radiation end of the second antenna 130 is grounded, and the ground end of the first antenna 120 is far from the radiation end of the first antenna 120, so that the interference of the ground end to the signal of the first antenna 120 can be reduced, and the radiation efficiency of the first antenna 120 is further improved. Similarly, the ground end of the second antenna 130 is far from the radiation end of the second antenna 130, so that the interference of the ground end to the signal of the second antenna 130 can be reduced, and the radiation efficiency of the second antenna 130 can be improved.

In some embodiments, the grounding positions of the first antenna 120 and the second antenna 130 may also be adjusted according to actual requirements.

In some embodiments, as shown in fig. 3, the second antenna 130 includes a third radiation branch 131 and a fourth radiation branch 132, the third radiation branch 131 and the fourth radiation branch 132 are both formed on the second frame 112, the third radiation branch 131 is used for transceiving low-frequency radio-frequency signals of LTE, and the second radiation branch 122 is used for transceiving medium-high-frequency radio-frequency signals. The end of the third radiation branch 131 far from the fourth radiation branch 132 forms a radiation end, and the end of the fourth radiation branch 132 far from the third radiation branch 131 forms a radiation end, so that the distance between the radiation end of the third radiation branch 131 and the radiation end of the fourth radiation branch 132 is increased as much as possible, so as to increase the isolation between the two, and further reduce the mutual interference between the two.

For example, there may be three second through slits 1161, three second through slits 1161 are disposed between the second frames 112 at intervals and all communicate with the second through slits 1162, and the third radiation branch 131 and the fourth radiation branch 132 are located between the adjacent second through slits 1161 respectively. The lengths of the third radiation branch 131 and the fourth radiation branch 132 are not limited herein, for example, the length of the third radiation branch 131 may be λ/4 or 3 λ/4 of the working frequency band of the second antenna 130 when receiving and transmitting the low-frequency radio frequency signal of the LTE, or may be other lengths, which only needs to satisfy the frequency band of the second antenna 130 for receiving and transmitting the signal. The second antenna 130 is used for receiving and transmitting a low-frequency radio frequency signal of long term evolution LTE and a medium-high frequency radio frequency signal of long term evolution LTE through the third radiation branch 131 and the fourth radiation branch 132, so that a situation that each radiator is blocked by a user to be unable to radiate an antenna signal can be avoided, and radiation efficiency of the antenna signal can be improved.

In addition, in some embodiments, the second antenna 130 can also simultaneously transmit and receive low, medium, and high frequency radio frequency signals through the third radiation branch 131 or the fourth radiation branch 132.

In some embodiments, the first spacing gap 1152, the second spacing gap 1162, the first through gap 1151 and the second through gap 1161 may be filled with an insulating medium, so as to enhance the connection structural strength between the first antenna 120 and the display portion 110 and the connection structural strength between the second antenna 130 and the display portion 110, thereby enhancing the overall strength of the first antenna 120 and the second antenna 130, and simultaneously increasing the overall strength of the display portion 110. The filled insulating medium can be plastic or rubber or other non-conductive materials, and the two can be fixed by injection molding and integral molding. The insulating material can be made of a material with a smaller dielectric constant, so that the loss of gap radiation can be reduced, and the efficiency of gap radiation is improved.

Accordingly, the value of the corresponding capacitor, inductor, or LC circuit is set according to the frequency band corresponding to the first antenna 120. Similarly, for the second antenna 130 and the third antenna 140 having multiple frequency bands, the frequency band switching circuits corresponding to the second antenna 130 and the third antenna 140 may also be disposed to control the circuits of the second antenna 130 and the third antenna 140 for transceiving different frequency bands, which is not described herein again.

In some embodiments, the wearable electronic device 100 may further include a number of first feeding points coupled to the first antenna 120, a number of second feeding points coupled to the second antenna 130, a third feeding point coupled to the third antenna 140, and so on, for feeding current signals so that the first antenna 120, the second antenna 130, and the third antenna 140 of the wearable electronic device 100 radiate corresponding signals.

For example, in some embodiments, when the third antenna 140 respectively receives and transmits the Wi-Fi signal or the GPS signal through the first radiator 141 and the second radiator 142, for example, two radiation sections with equal lengths are respectively formed at the connection point of the third feeding point and the first radiator 141 to the two ends, and the two radiation sections with equal lengths may be used to simultaneously radiate the same signal, so as to enhance the efficiency of the third antenna 140 in radiating the Wi-Fi signal.

Referring to fig. 1, in the present embodiment, the wearing portion 170 is connected to the display portion 110, specifically, the wearing portion 170 is connected to the frame 113 and detachably connected to the display portion 110 through a magnetic attraction structure, a buckle structure, and the like, and two ends of the wearing portion 170 are respectively connected to the frame 113 to form a ring shape, and further fixed to a wearing part (e.g., a wrist) of a user through the ring shape.

By connecting the wearing portion 170 to the connecting frame 113, the wearing portion 170 is not connected to the first frame 111 and the second frame 112, so that interference of the wearing portion 170 to the first antenna 120 and the second antenna 130 can be reduced, for example, when the wearing portion 170 is a metal watch band, interference of metal to signals of the antennas can be generated, and at this time, the wearing portion 170 is connected to the connecting frame 113, so that interference of the wearing portion 170 to the first antenna 120 and the second antenna 130 can be reduced.

In some embodiments, the wearing portion 170 includes a first band 171 and a second band 172, both the first band 171 and the second band 172 are connected to the display portion 110, and specifically, the first band 171 and the second band 172 are respectively connected to the connection frame 113, wherein the bands may be made of plastic, metal, a belt, a strap, a paper band, or the like, or may be made of two or more materials at the same time.

In some embodiments, as shown in fig. 5, when the wearing portion 170 includes the first band 171 and the second band 172, the third antenna 140 may include a first radiator 141 and a second radiator 142, wherein the first radiator 141 is disposed on the first band 171, and the second radiator 142 is disposed on the second band 172. The first radiator 141 may be provided on the second band 172, and the second radiator 142 may be provided on the first band 171. By arranging the first radiator 141 and the second radiator 142 on two different watchbands, signal interference between the first radiator 141 and the second radiator 142 can be reduced, for example, when the first radiator 141 is used for receiving and transmitting Wi-Fi signals and the second radiator is used for receiving and transmitting GPS signals, the distance between the first radiator 141 and the second radiator is relatively long, so that the isolation between the first radiator 141 and the second radiator can be reduced, and interference can be avoided. In some embodiments, the user can switch different antennas as desired by replacing the watch band, for example, the first watch band 171 can be replaced with the second watch band 172, or the second watch band 172 can be replaced with the first watch band 171.

In some embodiments, as shown in fig. 6, the wearing portion 170 includes a connection bracket 173 and an insulation tape 174, the insulation tape 174 may be made of plastic, rubber, silicon, a belt or a cloth tape, and the like, wherein the third antenna 140 may be disposed on the connection bracket 173, for example, a slot antenna is formed on the connection bracket 173 of the third antenna 140, or disposed on the wearing portion 170 by a laser direct structuring technique, a direct printing technique, a flexible circuit board, and the like, wherein the number of the insulation tapes 174 may be two, and the two insulation tapes 174 are oppositely spaced, and the connection bracket 173 is connected between the two insulation tapes 174. Interference with the signal of the third antenna 140 can be reduced by providing the insulating tape 174 on both sides of the connection bracket 173. In addition, the connecting bracket 173 can be covered by an insulating material such as plastic or silica gel, so as to prevent the connecting bracket 173 from being exposed, and to increase the connection strength between the third antenna 140 and the wearing portion 170.

In some embodiments, the wearing portion 170 may also be connected to the first frame 111 or the second frame 112, or both the first frame 111 and the second frame 112.

In some embodiments, as shown in fig. 7, the wearable electronic device 100 may further include a decoration 175 disposed on the wearing portion 170, the decoration 175 being exposed on a surface of the wearing portion 130, and the third antenna 140 being integrated with the decoration 175. The decoration may be a specific pattern (e.g., a product logo or other pattern) made of a metal material to decorate the appearance of the wearing portion 130, and at the same time, the third antenna 140 is exposed to the surface of the wearing portion 130, which may enhance the efficiency and signal strength of the third antenna 140 for transmitting and receiving signals.

In some embodiments, the wearing portion 170 may be made of a flexible material, wherein the flexible material refers to a material that can be deformed to some extent, and when the user wears the wearing portion (e.g., the wrist), the wearing portion 170 is fixed on the wearing portion of the user by bending, for example, to form a ring structure. Wherein the third antenna 140 may be a flexible antenna, for example, by disposing the third antenna 140 on a flexible FPC board. Because the deformation amount of the different parts of the wearing portion 170 in the bending process is different, the third antenna 140 may be disposed in a region of the wearing portion 170 where the deformation amount is smaller, for example, an end portion of the wearing portion 170 connected to the display portion 110 or an end portion far away from the display portion 110, so as to reduce or avoid the frequency deviation of the third antenna 140, where the frequency deviation refers to the amplitude of the frequency swing of the frequency modulated wave, and the frequency deviation may affect the spectrum width of the frequency modulated wave. Wherein the bandwidth of the third antenna 140 may be increased to reduce or avoid frequency offset, such as increasing the height of the third antenna 140.

In summary, the wearable electronic device 100 provided in the present application receives and transmits the LTE-long term evolution signal through the first antenna 120 and the second antenna 130, so as to achieve multiple input and multiple output of the LTE-long term evolution signal, which can reduce interference of a user holding the wearable electronic device to the antenna signal, and further, the wearable portion 170 is provided with the third antenna 130 that can be used for receiving and transmitting one of a GPS signal and a Wi-Fi signal, which can further reduce interference of holding the wearable electronic device and interference between antennas.
