In this embodiment, the feed network is electrically connected to the feed source, and may be implemented by a microstrip line, a CPW (coplanar waveguide) line, and the like, the feed network is disposed on the dielectric substrate 200, and is disposed on the two side surfaces of the dielectric substrate 200 with the grounding portion 210, and the feed network may be electrically connected to the feed point through a feed line. Through adjusting the feed network, the antenna structure of the intelligent wearable device can obtain better antenna performance in a required frequency band, and the multi-band and multi-functional communication function is met.

The invention further provides the intelligent wearable equipment. The intelligent wearable device comprises the intelligent wearable device antenna structure; and the number of the first and second groups,

the detailed structure of the antenna structure of the intelligent wearable device can refer to the above embodiments, and is not described herein again; it can be understood that, because the intelligent wearable device antenna structure is used in the intelligent wearable device of the present invention, embodiments of the intelligent wearable device of the present invention include all technical solutions of all embodiments of the intelligent wearable device antenna structure, and the achieved technical effects are also completely the same, and are not described herein again.

The intelligent wearable device further comprises a surface cover and a bottom shell, wherein the surface cover and the bottom shell are respectively arranged on two sides of the annular metal frame 100 of the antenna structure of the intelligent wearable device so as to form an installation cavity in a surrounding manner;

the electric control assembly is arranged in the installation cavity and electrically connected with the intelligent wearable device antenna structure.

In this embodiment, the material of the top cover and the bottom case may be plastic, tempered glass, metal, or other hard materials, which is not limited herein. The electric control assembly comprises a display module, an electric control board, a battery and the like. The face lid can be the touch-sensitive screen, and when display module was the display screen, face lid and display module accessible screen laminating assembly process integrated. The annular metal frame 100 may be a hollow structure, the surface cover covers one side of the annular metal frame 100, and the bottom case covers the other end of the annular metal frame 100, so that the surface cover, the annular metal frame 100, and the bottom case are sequentially stacked and form an installation cavity. The face cover is bonded with the annular metal frame 100 and the bottom shell is bonded with the annular metal frame 100 through waterproof glue, so that the face cover is waterproof with the annular metal frame 100 and the bottom shell is waterproof with the annular metal frame 100, external moisture cannot enter the installation cavity, and the electric control assembly and the like in the installation cavity can work normally and stably. The electronic control assembly can realize functions of calling, receiving and sending information, shooting, video calling, scanning two-dimensional codes, mobile payment, checking environment information, checking body information and the like. Therefore, in the present embodiment, the electronic control assembly includes a display module, a camera, a battery, a speaker, a microphone, a card seat assembly, a wireless communication module, and sensors for implementing various functions, wherein the sensors may be a gravity sensor, an acceleration sensor, a distance sensor, a heart rate sensor, an air pressure sensor, an ultraviolet detector, and the like. Wherein, wireless communication module among the automatically controlled subassembly can be WIFI, 5G communication module, GPS, bluetooth communication module etc. and wireless communication module is connected with the antenna structure electricity to receive and passback data through the antenna structure. The electronic control assembly may include elements for identification, such as a fingerprint sensor, facial recognition sensor, etc. The antenna structure is according to wireless communication module's difference, and the type and the quantity that set up are also different, for example when being provided with the WIFI module in intelligent wearing equipment, antenna structure then includes the WIFI antenna that can realize the WIFI communication, and when being provided with bluetooth communication module, antenna structure then includes the bluetooth antenna that can realize bluetooth communication etc..

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
