Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide an antenna, which is used for improving the isolation between two antennas, does not need to change the shape of a radiation unit of the antenna, and is suitable for miniaturized wearable electronic products. On the basis, the invention also provides a wearable electronic product comprising the antenna.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a structural diagram of an antenna according to an embodiment of the present invention. As shown in fig. 1, the antenna includes a first antenna 10 and a second antenna 11 with different operating frequencies, and further includes a spacer 12 disposed at a distal end of the first antenna 10 and a distal end of the second antenna 11, where the spacer 12 has a serpentine trace.
It should be noted that the antenna mentioned in this embodiment may include a plurality of antennas, and does not represent only two antennas, where the first antenna and the second antenna are only used for distinguishing two antennas with different operating frequencies. For example, there may be 3 antennas, an a antenna, a B antenna, and a C antenna, then the a antenna and the B antenna may be the first antenna and the second antenna, respectively, or the a antenna and the C antenna may be the first antenna and the second antenna, respectively, or the B antenna and the C antenna may be the first antenna and the second antenna, respectively.
In the embodiment, the tail end of the first antenna is connected with the tail end of the second antenna through the isolation part, when the current of the first antenna passes through the tail end, the current is still strong, but after passing through the isolation part, the current is attenuated, so that the influence on the second antenna is reduced; similarly, when the current of the second antenna passes through the tail end, the current is still strong, but after passing through the isolation part, the current is attenuated, so that the influence on the first antenna is reduced. The isolating part is provided with the snake-shaped routing, so that the path through which the current flows is increased, the attenuation of the current of the first antenna is larger after the current passes through the snake-shaped routing, and the influence on the second antenna is further reduced; similarly, the current of the second antenna is attenuated more after passing through the serpentine routing, so that the influence on the first antenna is further reduced. The isolation portion may be configured to perform an isolation function when one of the first antenna and the second antenna operates, or may be configured to perform an isolation function when both antennas operate.
The isolation portion in this embodiment may be directly connected to the end of the first antenna and the end of the second antenna, or may be coupled to each other. The shape of both ends of the spacer needs to be matched with the shape of the tip of the first antenna and the tip of the second antenna. In one embodiment, the spacer is copper metal. It is to be understood that the spacer may be made of metal, and may be made of nickel, gold, or the like, in addition to copper. In specific implementation, the method can be realized by adopting an LDS (laser direct structuring) or FPC (flexible printed circuit) process. Taking the isolation part as copper metal as an example for explanation, if the LDS process is adopted, the laser technology is utilized to directly form the isolation part on the target position by chemical plating, and if the PFC process is adopted, the copper metal is adopted as the base material. It is understood that the above two processes are only one specific application scenario, and one of the two processes may be selected according to actual situations.
It will be appreciated that the serpentine trace referred to in this embodiment is a serpentine trace, and the distance between the end of the first antenna and the end of the second antenna can be increased compared to a straight trace. Therefore, in a more tense layout space, the current path can be extended while occupying a smaller distance.
In addition, the specific shape of the snake-shaped routing is not limited, and the snake-shaped routing can be in a sawtooth shape, and of course, the snake-shaped routing can be in a regular sawtooth shape or an irregular sawtooth shape. In addition, the line width, the line length and the grooving depth of the snake-shaped routing need to be set according to the frequency point requirement with poor isolation, and the details are not repeated in this embodiment.
The antenna provided by the embodiment comprises a first antenna, a second antenna and an isolating part, wherein the first antenna and the second antenna have different working frequencies, the isolating part is arranged at the tail end of the first antenna and the tail end of the second antenna, and the isolating part is provided with a snake-shaped routing. Because the isolating part has the snakelike line of walking, prolonged the route of radiating current for the electric current of first antenna and the electric current of second antenna can the decay of great degree when passing through the isolating part, and then improve the isolation of first antenna and second antenna. Therefore, by adopting the technical scheme provided by the embodiment, the structure is simple, the shape of the radiation unit of the antenna is not required to be changed, the antenna can be realized through the LDS or FPC process, and the isolation of the two antennas can be obviously improved without occupying too much space for a miniaturized wearable electronic product with a tense layout space. Furthermore, the technical scheme does not need to change an antenna mould, and the debugging and testing period is short. Finally, the addition of the isolation portion increases the area (or length) of the main radiation ground of the antenna, and therefore, the efficiency of the antenna is improved.
Fig. 2 is a graph comparing the effect of the isolation between the isolation part and the non-isolation part provided by the embodiment of the invention. As shown in fig. 2, the solid line indicates the degree of isolation with the isolation portion, and the broken line indicates the degree of isolation without the isolation portion. As is apparent from fig. 2, the isolation between the first antenna and the second antenna is significantly improved by the isolation portion.
In the above embodiments, the first antenna is a full-band antenna, and the second antenna is a non-full-band antenna. It can be understood that the frequency band range of the full-band antenna is very large, and can cover a plurality of frequencies, for example, the first antenna is a 2G antenna/a 3G antenna/a 4G antenna. The frequency band range of the non-full band antenna is narrow, for example, the second antenna is a GPS antenna/a bluetooth antenna/a WIFI antenna. When first antenna and second antenna setting are in miniaturized wearable electronic product, first antenna and second antenna realize respective function respectively, through the isolation portion, have reduced the mutual interference of first antenna and second antenna for miniaturized wearable electronic product's signal quality improves.
In one embodiment, the end of the first antenna and the end of the second antenna are directly connected to the isolation portion, and in order to improve the stability of the first antenna, the second antenna and the isolation portion, the isolation portion is usually integrally provided with the first antenna and the second antenna. Of course, the two-piece connector can be arranged separately from one another and then fixed by a corresponding fixing method, for example, by a spring plate connection, a pressure welding connection, or a special connector. It should be noted that, compared with the split arrangement, the integrated arrangement occupies a small space, and is more suitable for miniaturized products, such as wearable electronic products.
In addition to the above implementation, in the present embodiment, the end of the first antenna and the end of the second antenna are both coupled to the isolation portion.
In fig. 1, the end of the first antenna and the end of the second antenna are directly connected through the isolation portion, that is, the current of the end of the first antenna and the current of the end of the second antenna directly flow to the isolation portion. In this embodiment, the terminal of the first antenna and the terminal of the second antenna are coupled to the isolation portion, respectively, that is, the current at the terminal of the first antenna and the current at the terminal of the second antenna do not directly flow to the isolation portion, but the currents are coupled to the isolation portion by means of electromagnetic coupling. The coupling connection can be used as an alternative in the case that the direct connection is difficult to be realized due to the structural space limitation, and the performance is better than the direct connection under a certain antenna design environment. In addition, the coupling connection reduces the risk of wire breakage or crack when the antenna LDS or FPC is too narrow in the antenna process implementation.
In addition to the end of the first antenna and the end of the second antenna being directly connected to the isolation portion and the end of the first antenna and the end of the second antenna being coupled to the isolation portion in fig. 1, a combination of coupling and direct connection may be used, that is, the end of the first antenna may be directly connected to the isolation portion, the end of the second antenna may be coupled to the isolation portion, or the end of the first antenna may be coupled to the isolation portion and the end of the second antenna may be directly connected to the isolation portion. Fig. 3 is a structural diagram of another antenna according to an embodiment of the present invention. As shown in fig. 3, the end of the first antenna 10 is coupled to the isolation portion 12, and the end of the second antenna 11 is directly connected to the isolation portion 12.

Because the isolating part has the snakelike line of walking, prolonged the route of electric current for the electric current of first antenna and the electric current of second antenna can the attenuation of great degree under the effect of isolating part, and then improve the isolation of first antenna and second antenna. Therefore, the technical scheme provided by the embodiment is simple in structure, the shape of the radiating unit of the antenna is not required to be changed, and the isolation of the two antennas can be obviously improved without occupying too much space for a miniaturized wearable electronic product with tense layout space.
