The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the wearable device provided in the embodiment of the present invention, as shown in fig. 1, the wearable device may include: a wearing body 1, a wearing band 2, a first antenna component 3, and a second antenna component 4; the wearing body 1 is connected with the wearing belt 2; the first antenna component 3 is provided on the wearing body 1, and the second antenna component 4 is provided on the wearing belt 2; the first antenna component 3 and the second antenna component 4 are connected; wherein the second antenna component 4 has a first end and a second end, the first end of the second antenna component 4 being connected to the first position 3a of the first antenna component 3 and the second end of the second antenna component 4 being connected to the second position 3b of the first antenna component 3.

It is to be understood that the second antenna component 4 may be a bold part of fig. 1.

The utility model provides a wearing equipment has increased the second antenna unit on only first antenna unit's basis among the prior art scheme, and the second antenna unit sets up in wearing the area, can prolong the electric length of antenna effectively to can promote the communication efficiency of antenna, strengthen wearing equipment's communication effect.

It will be appreciated that in an example, the effective electrical length of the first antenna component 3 may be the length from the first position 3a to the second position 3b in a counter clockwise direction, for example, when the impedance of the portion between the first position 3a of the first antenna component 3 and the second position 3b of the first antenna component 3 is relatively large. At this time, the electrical length of the antenna in the wearable device may be the length of the first antenna part 3 from the first position 3a to the second position 3b in the counterclockwise direction plus the length of the second antenna part 4.

Optionally, in an embodiment of the present invention, there may be at least one break point between said first position 3a of said first antenna component 3 and said second position 3b of said first antenna component 3. In this way, it is possible to extend the electrical length of the antenna more conveniently by providing a break point between the first position 3a and the second position 3b of the first antenna component 3.

It should be understood that the specific number of the break points between the first position 3a of the first antenna component 3 and the second position 3b of the first antenna component 3 in the present invention can be set according to actual requirements, and is not limited herein. For example, the breakpoint may be one, two, three, or four, etc.

Further, in an embodiment of the present invention, as shown in fig. 2, fig. 2 is a schematic structural diagram of a wearable device provided in an embodiment of the present invention. It is to be understood that the second antenna component 4 may be a bold part in fig. 2.

There may be two breakpoints between said first position 3a of said first antenna element 3 and said second position 3b of said first antenna element 3: a first break point 31 and a second break point 32; the wearable device may further include: a power feeding means 5; the wearing body may include: a grounding member 6; the feeding block 5 may have a first end and a second end, the first end of the feeding block 5 may be connected to the grounding block 6, and the second end of the feeding block 5 may be connected to a portion of the first antenna element 3 between the first disconnection point 3a and the second disconnection point 3 b. In this way, the antenna can be excited by setting the feeding part, and the maximum radiation direction of the antenna can be adjusted by changing the position of the feeding part.

The feeding component 5 may be a spring plate or a capacitor; the grounding part 6 may be a metal plate for grounding the feeding part 5.

It is understood that the first antenna element 3 provided on the wearing body 1 and the second antenna element 4 provided on the wearing band 2 may constitute a radiator portion, and the feeding element 5 having the first end connected to the ground element 6 and the second end connected to a portion between the first disconnection point 3a and the second disconnection point 3b may constitute a feeding portion, which may be regarded as a slot antenna. The slot antenna may be an antenna formed by slotting on a conductor plane, and may also be referred to as a slot antenna; a typical slot shape is a long strip, approximately half a wavelength in length; the slot may be fed by a transmission line across its narrow side, or by a waveguide or resonant cavity. At this time, a radio frequency electromagnetic field is excited on the gap, and electromagnetic waves are radiated to the space.

For ease of understanding, the following are exemplified here:

for example, the antenna may be low frequency in case of natural resonance, in which case the antenna may be in half-wave mode. As shown in fig. 2, since the second antenna component 4 can be disposed on the wearing belt 2, the electric field strong point is also near the wearing belt 2, so as to increase the distance from the casing of the wearing device, improve the clearance area, and effectively improve the efficiency of the low-frequency antenna compared with the prior art. At this time, compared with the prior art in which only the first antenna element 3 is disposed on the wearing body 1 (the radiation direction of the first antenna element 3 is mostly toward the ground), the maximum positions of the pattern gain of the antenna in the half-wave mode in fig. 2 can be 3 o 'clock and 9 o' clock directions, and thus, the corresponding scheme in fig. 2 is more suitable for a sports scene.

The clearance area can enable metal to be far away from the antenna body, and the resonance frequency can be changed by changing the size of the clearance area. For example, the clearance of the antenna of the handset is the size of the antenna area without ground.

In addition, in the case of Ultra Wide Band (UWB) high frequency (6.25-6.75G and 7.75-8.25G), the second antenna element 4 is added to the conventional art, so that the radiation area of the antenna is increased, and the antenna has a wideband characteristic in a high-order mold, and thus, the antenna can be used as an antenna for UWB application.

The UWB technology is a wireless carrier communication technology, and uses nanosecond-level non-sinusoidal narrow pulses to transmit data instead of sinusoidal carriers, so that the occupied frequency spectrum range is wide. The UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, and is particularly suitable for high-speed wireless access in indoor and other dense multipath places.

The higher order mode is an electromagnetic wave with a relatively high mode. When electromagnetic waves are transmitted in a waveguide, boundary conditions need to be met, the solution of the electromagnetic waves is generally a Bezier function, zero points of the Bezier function are characteristic values, the value of each zero point represents a mode capable of being transmitted, and due to the fact that the Bezier function has infinite zero points, infinite modes can exist in the waveguide. Therefore, the first zero point corresponds to the lowest mode, which is called the fundamental mode; the higher order mode is relative to the fundamental mode, i.e. the higher order mode corresponds to the other zeros of the bessel function, and since the zero values of the bessel function are gradually increased, the latter modes are all called higher order modes.

The microstrip line mentioned above is optional parts in the wearing equipment that the embodiment of the utility model provides. It should be understood that the embodiment of the present invention provides a wearable device including a microstrip line, which can be selected according to the actual application scenario, and is not limited herein.

Wherein the microstrip line 9 is a microwave transmission line formed by a single conductor strip supported on a dielectric substrate. The microstrip line is suitable for manufacturing a planar structure transmission line of a microwave integrated circuit. Compared with a metal waveguide, the waveguide has the advantages of small volume, light weight, wide use frequency band, high reliability, low manufacturing cost and the like; but the loss is slightly larger and the power capacity is small. In the early 60 s, microwave integrated circuits were formed due to the development of microwave low-loss dielectric materials and microwave semiconductor devices, so that microstrip lines were widely used, and various types of microstrip lines appeared in succession. Typically by thin film processes. The dielectric substrate can be made of materials with high dielectric constant and low microwave loss; the conductor should have the characteristics of high conductivity, good stability, strong adhesion with the substrate, and the like.

For ease of understanding, the following are exemplified here:

for example, referring to fig. 9, the feeding block 5 and the housing on the grounding block 6 have two contact points a and B, wherein the point a is connected to the grounding block 6 through a microstrip line 9 near the feeding block 5 and A, B. The position of point B may be about 90 degrees clockwise from point a, and the length of microstrip line 9 may be about 1/4 of the wavelength. If the feeding component 5 is only placed at the point A, no point B is contacted, and the maximum radiation direction can be in a 3 o 'clock direction and a 9 o' clock direction; if the feed unit 5 is only placed at the point B, the contact point A is not arranged, and the maximum radiation directions are 6 o 'clock direction and 12 o' clock direction; therefore, as shown in fig. 9, when there are two contact points a and B, they are in an orthogonal mode. At this time, the point a and the point B can excite two orthogonal modes at the same time, and the excitation phase at the point B lags behind the point a by routing through the microstrip line 9, so the final directional diagram maximum radiation direction of the structure can be perpendicular to the screen, and the structure has a circular polarization characteristic.

When the included angle between the polarization plane of the radio wave and the geonormal plane changes periodically from 0 to 360 degrees, that is, the electric field is constant in magnitude and changes in direction with time, and the projection of the track at the end of the electric field vector on a plane perpendicular to the propagation direction is a circle, the circular polarization is called. Circular polarization can be achieved when the horizontal and vertical components of the electric field are equal in amplitude and 90 ° or 270 ° out of phase. If the polarization plane rotates along with time and forms a right-handed spiral relation with the electromagnetic wave propagation direction, right-handed circular polarization is called; conversely, if the left-handed circular polarization is formed, the left-handed circular polarization is called.

The utility model provides a wearing equipment can set up the microstrip line between feed part and first antenna part, has the phase difference in the aspect of the directional diagram through the both ends of microstrip line to realized the circular polarization of antenna when the low frequency, restrained multipath interference and improved the polarization mismatch loss, be applicable to various communication more and use, increase positioning accuracy and user experience.
