Abstract
Provided in the invention is a class loop antenna of wearable equipment. The antenna comprises a dielectric substrate, a class loop antenna unit, and a feed network. The dielectric substrate is connected with the class loop antenna unit by the feed network. The class loop antenna unit is provided with a first output terminal and a second output terminal; and the first output terminal and the second output terminal are connected. According to the invention, the class loop antenna unit is integrated to the dielectric substrate directly, so that assembling is avoided and thus the cost is low. The characteristic of wide bandwidth of the class loop antenna is kept; the two output terminals of the class loop antenna are connected, so that a problem of low-frequency radiation efficiency is solved. The two frequency bands are realized by one antenna, so that a problem of isolation is solved.
Description
Technical field
The present invention relates to field of wireless communication, particularly relate to the antenna of a kind of wearable device.
Background technology
Wearable antenna class ring is a kind of electronic equipment can being implanted in medicated clothing, by itself and the connection of the Internet, Ren Menke
Greatly facilitate daily life obtaining time, temperature etc. easily, if Fig. 1 is existing class loop antenna, its ring
On the first outfan 12 ' and the second outfan 13 ' be off, low frequency radiation-efficiency is poor, simultaneously because multi-section antenna is very
Working in little region simultaneously, can cause serious electromagnetic interference, the prevailing transmission approach of electromagnetic interference is the coupling between antenna
Close, in order to realize the normal work between each antenna, it is to avoid interfere, it is desirable to reduce the harmful coupling between antenna.Therefore, carry
High isolation between antennas and improve low frequency radiation-efficiency and become the precondition realizing antenna compatible operations.
Summary of the invention
The technical problem to be solved in the present invention, is to provide the class loop antenna of a kind of wearable device, including medium substrate, class ring
Antenna, feeding network, described medium substrate is connected with described class loop antenna by described feeding network, and described class loop antenna sets
The first outfan and the second outfan, described first outfan is had to be connected with described second outfan.
Further, described feeding network includes earth point and distributing point.
Further, described medium substrate is circular circuit board.
Further, described class loop antenna is hoop antenna.
The present invention is by being directly integrated into class loop antenna on medium substrate, it is not necessary to assembles, low cost, has continued class ring sky simultaneously
The feature that tape is wide, and two outfans of class loop antenna are connected, the problem improving low frequency radiation-efficiency, with an antenna
Realize two frequency ranges, it is to avoid isolation problem occurs.
Accompanying drawing explanation
The present invention is further illustrated the most in conjunction with the embodiments.

Detailed description of the invention
Refer to Fig. 2, Fig. 3, be the class loop antenna 3 of a kind of wearable device as highly preferred embodiment of the present invention, including being situated between
Matter substrate 2, class loop antenna 3, described medium substrate 2 is connected with described class loop antenna 3 by feeding network 1, described class ring
Antenna 3 is provided with the first outfan 12 and the second outfan 13, and described first outfan 12 is connected with described second outfan 13
Connect.
Described feeding network 1 includes that earth point 14 and distributing point 11, described medium substrate 2 are circular circuit board, described class ring
Antenna 3 is hoop antenna.
This antenna is f1 at lowest resonant frequency, owing to class loop antenna 3 has 2 times of resonance, i.e. also has deeper at 2f1 frequency
Resonance.Debug plus matching network, can effectively cover 2G, ISM (LORA, WIFI ah etc.) at f1, can adjust at 2f1
Whole for f2, can effectively cover the networks such as GPS/BEIDOU, 3G.The S11 figure of this antenna, refering to Fig. 4, all has at f1 and f2
There is excellent radiance.Being detected by experiment, its efficiency is respectively 22% and 38%, meets radio-frequency performance requirement.Refering to figure
5 (a) and Fig. 5 (b), this antenna can excite different patterns at f1 and f2 frequency respectively.
In sum, the present invention is by being directly integrated into class loop antenna on medium substrate, it is not necessary to assemble, low cost, same to time delay
Continue the feature that class loop antenna band is wide, and two outfans of class loop antenna have been connected, the problem improving low frequency radiation-efficiency, use
One antenna realizes two frequency ranges, it is to avoid isolation problem occur.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements and is not subject to the restrictions described above,
As long as the improvement of the various unsubstantialities that the method design that have employed the present invention is carried out with technical scheme, or the most improved by the present invention
Design and technical scheme directly apply to other occasion, all within protection scope of the present invention.
