The wearable device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, an embodiment of the present application provides a wearable device, as shown in fig. 1, the wearable device includes: the antenna comprises a radio frequency circuit and an antenna, wherein the radio frequency circuit is electrically connected with the antenna, the antenna comprises a first radiating body 10 and at least two feed points 20, one end of each feed point 20 in the at least two feed points 20 is electrically connected with the first radiating body 10, and the other end of each feed point 20 is grounded.

The working principle of the embodiment of the application can be referred to as the following expression:

the at least two feed points 20 are all connected to the first radiator 10, and then the at least two feed points 20 can radiate through the first radiator 10, that is, the at least two feed points 20 can share the first radiator 10, and only the first radiator 10 needs to be set in the wearable device, and it is not necessary to set a plurality of independent radiators isolated from the feed points to the radiation ends, thereby reducing the number of radiators and the volume occupied in the wearable device, and because the radiators are part of antennas, thus, the volume occupied by the antennas in the wearable device is reduced, and further, the volume of the whole wearable device is reduced. Meanwhile, the transmitting and receiving capacity of the antenna is improved, the communication power consumption of the wearable device can be reduced, and the user experience is improved.

Wherein, the types of the at least two feed points 20 may be the same or different. When the types of the at least two feed points 20 are different, the connection positions of any two feed points 20 of the at least two feed points 20 and the first radiator 10 may also be different.

For example: the length of the radiator corresponding to the radiation signal in each feed point 20 is generally 1/4 of the wavelength of the radiation signal, so that the connection position of the feed point 20 and the first radiator 10 can be determined according to the wavelength of the radiation signal in each feed point 20, and thus, the following steps are performed: the radiator corresponding to each feed point 20 may be considered as at least a part of the first radiator 10, and the length of the radiator corresponding to each feed point 20 is determined according to the wavelength of the radiation signal in the feed point 20.

It should be noted that the length of the radiator corresponding to each feed point 20 may be: the length between the connection point of the feed point 20 to the first radiator 10 and one end of the first radiator 10.

Wherein one end of each feed point 20 is electrically connected to the first radiator 10 and the other end of each feed point 20 is grounded, so that a monopole antenna can be constructed such that the radiation energy of the radiation signal of the feed point 20 is mainly concentrated at one end of the connection point with the first radiator 10, thereby enhancing the radiation intensity of the radiation signal in the feed point 20.

It should be noted that the radiator in the present embodiment may also be referred to as a vibrator, that is, the first radiator 10 may also be referred to as a vibrator.

In addition, the radio frequency circuit in this embodiment may provide a radio frequency signal to the antenna, so that the radio frequency signal may be radiated to an external environment through the antenna.

As an alternative embodiment, referring to fig. 2, the wearable device further comprises a transceiver 30, a filter 40 and a matching circuit 50, and the other end of each feed point 20 is electrically connected to the transceiver 30 through the filter 40 and the matching circuit 50.

The transceiver 30 may be grounded, so that the other end of each feed point can be grounded through the transceiver 30, thereby further enhancing the grounding effect of each feed point.

Because the other end of each feed point 20 is electrically connected to the transceiver 30 through the filter 40 and the matching circuit 50, each filter 40 and the corresponding matching circuit 50 can achieve isolation between the feed point 20 connected to the filter 40 and the matching circuit 50 and other feed points 20, that is, the operating state of the feed point 20 does not affect the operating states of other feed points 20; meanwhile, the isolation between the feed point 20 and other feed points 20 is not required to be realized through switching, so that the radiation signal in each feed point 20 is always in an optimal working state; in addition, the filter 40 may perform out-of-band filtering (i.e., have a filtering function) and feed point 20 isolation functions.

The number and type of the transceivers 30 are not limited herein, and as an alternative embodiment, the number of the transceivers 30 may be one, so that the at least two feed points 20 are connected to the transceiver 30, that is, the wavelength and type of the radiation signal in the two feed points 20 are the same, but the radiation performance and flexibility of the radiation mode of the radiation signal are enhanced because the radiation signal can be radiated by the at least two feed points 20 and the first radiator 10.

As another alternative embodiment, the number of the transceivers 30 is at least two, the at least two transceivers 30 are electrically connected to the at least two feed points 20 one by one, and the operating frequency bands of the at least two transceivers 30 are not completely the same.

The operating frequency bands of at least two transceivers 30 are not completely the same, which can be understood as: there is at least a partial frequency band mismatch between the operating frequency bands of any two transceivers 30 of the at least two transceivers 30, and of course, the operating frequency bands of any two transceivers 30 of the at least two transceivers 30 may be completely different.

Wherein each feed point 20 may correspond to a transceiver 30, and thus may include a plurality of transceivers 30, such as: referring to fig. 2, a wireless (LB) transceiver 31, a Positioning System (GPS) transceiver 32, and a medium-high frequency transceiver, which may be an MHB transceiver 33, may be included, and of course, the MHB transceiver 33 may further include a plurality of sub-transceivers (e.g., including an MHB1 transceiver, an MHB2 transceiver, and an MHB3 transceiver), and the plurality of sub-transceivers may be connected to one feed point 20 (the feed point 20 may be a second feed point 22) through the same switch 60.

Thus, with the plurality of kinds of transceivers 30, the wearable device can transmit and receive a plurality of kinds of radiation performance simultaneously, so that the wearable device can have a plurality of functions.

Optionally, referring to fig. 1 to fig. 3, the at least two feed points 20 include a first feed point 21 and a second feed point 22, where the first feed point 21 operates in a first frequency band, and the second feed point 22 operates in a second frequency band, and the first frequency band is lower than the second frequency band;

one end of the first radiator 10 is an open end 11, the second feed point 22 and the second connection point of the first radiator 10 are located between the open end 11 and the first connection point, and the first connection point is the connection point of the first feed point 21 and the first radiator 10.

The first frequency band may be referred to as a low frequency band, and the frequency range thereof may be: 800-: 1700 + 2700 MHZ.

The LB transceiver in the above embodiments may operate in a low frequency band, and the MHB transceiver may operate in a medium and high frequency band.

Like this, owing to included first feed point 21 and second feed point 22, and first feed point 21 work at first frequency channel, second feed point 22 work at the second frequency channel to make wearing equipment work when first frequency channel and wearing equipment work at the second frequency channel, interference between the two is less, can guarantee wearing equipment work the normal realization of radiation function when first frequency channel and second frequency channel.

The positioning system feed point 23 may also be referred to as a GPS feed point, and its operating frequency band may be: 1575 MHZ.

In this way, the wearable device can also have a positioning function due to the positioning system feed point 23, so that the diversity of functions of the wearable device is further increased.

Alternatively, referring to fig. 1 and 3, the other end of the first radiator 10 is a short-circuited end 12. In this way, since the other end of the first radiator 10 is the short end 12, the radiation signal can be concentrated on the open end 11 of the first radiator 10, and thus the radiation performance of the first radiator 10 can be further enhanced.

Optionally, referring to fig. 5, the wearable device further includes a housing 70, and the first radiator 10 is disposed on the housing 70.

As an alternative embodiment, referring to fig. 1, 5 and 6, the case 70 may include a case 74, a metal bezel 72 and a metal back case 76, the metal bezel 72 and the metal back case 76 may be respectively and fixedly connected to two opposite surfaces of the case 74, and the first radiator 10 may be disposed on the case or the metal bezel 72, so that shielding of the first radiator 10 by other components in the case 74 is reduced, thereby increasing a headroom of the first radiator 10 and enhancing a radiation performance of the first radiator 10.

As another alternative, referring to fig. 1, 5 and 6, the case 70 may include a case 74 and a metal back case 76, the metal back case 76 is fixedly connected to one side of the case 74, and the first radiator 10 is disposed on the case 74, so that, compared with the above embodiments, the metal bezel 72 is not required to be disposed in the present embodiment, the thickness of the whole wearable device is reduced, and the use cost is reduced.

It should be noted that the watch case 74 may also be provided with a plurality of function buttons 75, such as: may include a power-on button, a select button, etc. In addition, in the two embodiments, the other end of each feed point 20 may be connected to the metal back case 76 and grounded through the metal back case 76, so that the grounding effect of the feed point 20 may be enhanced, and at the same time, the feed point 20 only needs to be connected to the metal back case 76, which also increases the assembly efficiency of the feed point 20.

In addition, a display module 73 may be further disposed on the casing 70, the display module 73 is used for displaying content, and the display module 73 may be disposed on the watch case 74. Of course, the opposite sides of the case 74 may also be provided with a band 71.

Optionally, the first radiator 10 constitutes at least a part of the housing 70 of the wearable device. In this way, it is not necessary to separately provide the first radiator 10 on the case 70, so that the thickness of the entire case 70 can be further reduced.

Since the range of the working frequency band of the radiation signal in the WIFI feed point 24 at least partially coincides with the range of the second frequency band, a second radiator 80 needs to be separately provided for the radiation signal in the WIFI feed point 24. Like this, can guarantee that wearing equipment still has the WIFI function to wearing equipment's function has further been increased.

In addition, since the second radiator 80 and the first radiator 10 constitute a loop radiator and the opposite ends of the first radiator 10 and the second radiator 80 are spaced apart from each other, the mutual interference between the second radiator 80 and the first radiator 10 can be reduced.

Of course, in order to improve the interference rejection capability, an insulator may be filled in a space between the first end of the second radiator 80 and the first end of the first radiator 10, and a space between the second end of the second radiator 80 and the first radiator 10, for example: one insulator may be fixedly connected to the first end of the second radiator 80 and the first end of the first radiator 10, and similarly, the other insulator may be fixedly connected to the second end of the second radiator 80 and the second end of the first radiator 10, so that the interference resistance between the first radiator 10 and the second radiator 80 is enhanced, and the connection strength between the first radiator 10 and the second radiator 80 is enhanced.

In addition, referring to fig. 3 and 4, F1 in fig. 3 indicates the length of the radiator corresponding to the radiation signal in the first feed point 21 when operating, and of course, the frequency band corresponding to the radiation signal may also be referred to as an F1 frequency band; f2 represents the length of the radiator corresponding to the radiation signal in the third feed point 23 when operating, and the frequency band corresponding to the radiation signal may also be referred to as an F3 frequency band; f3 represents the length of the radiator corresponding to the operation of the radiation signal in the second feed point 22, and the frequency band corresponding to the radiation signal may also be referred to as F3 frequency band.

The antenna matching of the GPS feed point (third feed point 23) to the GPS front-end filter is responsible for adjusting the phase position of each frequency band from the GPS feed point to the GPS front-end filter, and the F1 and F3 positions are thrown to the vicinity of the open circuit point shown in the smith chart. The antenna matching from the middle-high frequency feed point (the second feed point 22) to the ANT end (the antenna end) of the middle-high frequency duplexer is responsible for adjusting the phase position of each frequency band from the middle-high frequency feed point to the ANT end with the middle-high frequency duplexer, and the position of F3 is thrown to the vicinity of an open circuit point shown in a Smith chart; the F1 position is preferably swung to a position near the open circuit point shown in the smith chart and then swung to a position near the short circuit point shown in the smith chart.

Wherein, the separator 90 can be grounded through a plurality of feed points 20, for example: the spacer 90 may be connected to the metal back case 76 through two feeding points, i.e., grounded through the metal back case 76, so that the grounding performance is good.

In addition, the spacer 90 may be fixedly connected to the second end of the second radiator 80 and the second end of the first radiator 10 by an insulator, respectively. Reference may be made in particular to the corresponding statements of the insulating element in the above embodiments.

In this way, since the spacer 90 is disposed between the second end of the second radiator 80 and the second end of the first radiator 10, the interference rejection between the first radiator 10 and the second radiator 80 may be further enhanced.
