Among them, the design of the metal shell has become the trend and trend of mobile terminal design due to its structural strength advantage and the all-metal material texture advantage, and it is more and more popular among users. The all-metal back cover design is a category of mobile terminal design and is one of the research hotspots. However, it is well known that due to the "electrostatic shielding" effect of the metal, the mobile terminal of the all-metal back cover cannot effectively radiate or accept the electromagnetic model, which is liable to cause a drop in antenna performance.
鉴于此种情况,现有技术针对全金属后盖做了一定的研究,对传统天线PIFA、MONOPOLE和LOOP在全金属后盖的终端的应用进行了对比,发现这些天线结构均存在无法既兼顾天线的辐射性能,又不破坏金属后壳外观的一致性或存在占用空间较大的问题。为了解决上述问题,现有技术提出了一种针对无净空金属后壳的新型耦合馈电天线,包括PCB板01以及设于PCB板上的天线主体02,如图1所示。然而,该天线设计虽然能够满足移动终端外观全金属后盖的需求,但是谐振频率主要靠改变缝隙尺寸进行改变,调整不够灵活,方向也不可调整,且此设计需要很大的天线走线面积和高度,无法满足目前移动终端薄、高屏占比等极致外观的需求。In view of this situation, the prior art has done some research on the all-metal back cover, and compared the application of the traditional antennas PIFA, MONOPOLE and LOOP in the terminal of the all-metal back cover, and found that these antenna structures can not both take care of the antenna. The radiation performance does not destroy the consistency of the appearance of the metal back shell or the problem of large space occupation. In order to solve the above problems, the prior art proposes a novel coupled feed antenna for a clean-free metal back shell, comprising a PCB board 01 and an antenna body 02 disposed on the PCB board, as shown in FIG. However, although the antenna design can meet the requirements of the full metal back cover of the mobile terminal, the resonant frequency is mainly changed by changing the slot size, the adjustment is not flexible enough, the direction is not adjustable, and the design requires a large antenna routing area and The height cannot meet the demand for the ultimate appearance of thin, high-screen ratios of mobile terminals.
因此,如何在全金属后盖以及高屏占比极致外观的移动终端中灵活实现天线设计和调谐,满足未来移动终端对极致外观和天线性能的需求是本领域技术人员需要解决的问题。
Therefore, how to flexibly implement antenna design and tuning in an all-metal back cover and a mobile terminal with a high screen ratio and an extreme appearance, and satisfying the demand for the extreme appearance and antenna performance of the mobile terminal in the future are problems to be solved by those skilled in the art.

It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.
在手机、平板电脑等移动终端设备行业中,随着用户对移动终端外观的要求不断提高,越来越多金属外观的移动终端出现在市场上,但绝大数移动终端是金属中框或者半金属后盖(上下塑料开窗)设计,只有极少数移动终端后盖是全金属的。In the mobile terminal equipment industry such as mobile phones and tablet computers, as users' requirements for the appearance of mobile terminals continue to increase, more and more metal-appearing mobile terminals appear on the market, but most mobile terminals are metal middle frames or half. Metal back cover (upper and lower plastic window) design, only a few mobile terminal back cover is all metal.
现有已经公布的使用在全金属后盖移动终端上的是利用***地的耦合金属分支的常规PIFA天线,如图1所示,该天线包括PCB板01以及设于PCB板上的天线主体02。其中,如图2所示,天线主体02包括一馈电结构,该馈电结构由馈点0201分为第一馈电分支0202和第二馈电分支0203,第一馈电分支0202分别与第一寄生耦合分支0204和第二寄生耦合分支0205耦合,第二馈电分支0203与第一寄生耦合分支0204耦合。从图中可以看出,尽管该天线的设计满足外观全金属后盖的需求,但是天线结构设计较为复杂,天线走线面积和高度较大,无法满足目前终端要求薄、高屏占比等极致外观的需求,且
主要靠改变馈电分支和寄生耦合分支之间的耦合间距调整谐振频率,调整比较单一、不够灵活,天线方向也不可调整,无法满足移动终端更高技术的需求。The conventionally disclosed use on the all-metal back cover mobile terminal is a conventional PIFA antenna utilizing a systematic coupling metal branch, as shown in FIG. 1, the antenna includes a PCB board 01 and an antenna body 02 disposed on the PCB board. .

The first feed branch 0202 and the first feed branch respectively A parasitic coupling branch 0204 is coupled to a second parasitic coupling branch 0205, which is coupled to the first parasitic coupling branch 0204. It can be seen from the figure that although the design of the antenna satisfies the requirements of the appearance of the full metal back cover, the antenna structure design is relatively complicated, and the antenna routing area and height are large, which cannot meet the requirements of the current terminal requirements, high screen ratio, etc. Appearance needs, and
The resonance frequency is mainly adjusted by changing the coupling pitch between the feed branch and the parasitic coupling branch. The adjustment is relatively simple, not flexible enough, and the antenna direction is not adjustable, which cannot meet the higher technical requirements of the mobile terminal.
本发明实施例中,天线***包括反射单元。受激单元和引向辐射单元,其中,反射单元即为移动终端的全金属后盖,充分利用了全金属后盖作为天线***的一部分,减少了天线***的设计单元,而受激单元为第一金属走线,可以通过馈电点与全金属后盖连接,使得天线***的馈电结构设计较为简单,引向辐射单元则为第二金属走线,可以与第一金属走线耦合,通过对第一金属走线和第二金属走线进行调整,不仅可以减少金属走线占用的面积,以此来降低天线***结构实现的难度,也可以提高天线的辐射性能,灵活调整天线谐振频率和方向性。In an embodiment of the invention, the antenna system includes a reflective unit. The stimulated unit and the lead-in radiating unit, wherein the reflecting unit is an all-metal back cover of the mobile terminal, fully utilizing the all-metal back cover as part of the antenna system, reducing the design unit of the antenna system, and the stimulated unit is the first A metal trace can be connected to the all-metal back cover through the feeding point, so that the feeding structure of the antenna system is relatively simple, and the guiding radiation unit is a second metal trace, which can be coupled with the first metal trace. Adjusting the first metal trace and the second metal trace can not only reduce the area occupied by the metal trace, thereby reducing the difficulty of the antenna system structure, improving the radiation performance of the antenna, and flexibly adjusting the antenna resonance frequency and Directionality.

The all-metal back cover 1 of the mobile terminal is a reflection unit, and the set feed point 101 can be connected with the first metal trace 2 as the stimulated unit, and the entire feed structure is relatively simple in design, which reduces the complexity of the antenna system design. At the same time, in practical applications, a large area of the all-metal back cover 1 also serves as a reference ground for the antenna system, so that the design of the feed point is more flexible. In addition, the second metal trace 3, which is coupled to the first metal trace 1 as a lead radiation unit, is the main radiator of the antenna system, and can be used to flexibly adjust the antenna radiation and directivity, and occupy less metal traces. The area is advantageous for realizing the structure of the antenna system, and it is also easy to meet the needs of the extreme appearance such as the thinness of the mobile terminal and the proportion of the high screen.

On the side of the corresponding front cover, the first metal trace 2 and the second metal trace 3 are located at the upper or lower end of the all-metal back cover 1 in a relative position.

It can also meet the needs of the ultimate appearance of thin, high-screen ratios of mobile terminals.

引向辐射单元可以包括全球定位***GPS引向辐射单元和/或无线局域网WIFI引向辐射单元。The directing radiation unit may include a global positioning system GPS directing radiation unit and/or a wireless local area network WIFI leading radiation unit.
本实施例,在实际应用中,除了上述说明的GPS引向辐射单元和WIFI引向辐射单元,也可以是其它类型的引向辐射单元进行结合或单独使用,只要能够构成不同类型的天线***或组合天线***,具体此处不做限定。In this embodiment, in practical applications, in addition to the GPS directing radiation unit and the WIFI guiding radiation unit described above, other types of directing radiation units may be combined or used separately, as long as different types of antenna systems can be constructed or The combined antenna system is not limited herein.
具体的,本实施例中,若引向辐射单元包括GPS引向辐射单元和WIFI
引向辐射单元,即该天线***为GPS和WIFI组合天线***,如图6所示,第二金属走线3可以包括可调GPS金属走线301和可调WIFI金属走线302,该组合天线***可以同时工作在GPS和WIFI频段。Specifically, in this embodiment, if the guiding radiation unit includes a GPS directing radiation unit and the WIFI
Leading to the radiating unit, that is, the antenna system is a combined GPS and WIFI antenna system, as shown in FIG. 6, the second metal trace 3 may include an adjustable GPS metal trace 301 and an adjustable WIFI metal trace 302, the combined antenna The system can work in both the GPS and WIFI bands.
需要说明的是,本实施例中上述说明的可调GPS金属走线301和可调WIFI金属走线302相连成一个金属走线,即第二金属走线3为无断点结构,但可调GPS金属走线301和可调金属走线302分别与第一金属走线2的耦合位置可以不同,具体此处不做限定。It should be noted that, in the embodiment, the adjustable GPS metal trace 301 and the adjustable WIFI metal trace 302 are connected to form a metal trace, that is, the second metal trace 3 is a non-breakpoint structure, but is adjustable. The coupling positions of the GPS metal traces 301 and the adjustable metal traces 302 and the first metal traces 2 may be different, and are not limited herein.
具体的,基于可调GPS金属走线301和可调WIFI金属走线302相连成的第二金属走线3作为天线***的引向辐射单元,在实际的S11参数测试中,如图7所示,该图中的横坐标为频率(Frequency),单位为吉赫(GHZ),纵坐标为回波损耗参数(S-Parameter),单位为dB,从图中可以看到有两个波谷,第一个波谷为GPS频段,第二个波谷为WIFI频段,由此可知,本发明实施例的天线***可以为GPS和WIFI二合一***。Specifically, the second metal trace 3 connected by the adjustable GPS metal trace 301 and the adjustable WIFI metal trace 302 is used as the lead radiation unit of the antenna system. In the actual S11 parameter test, as shown in FIG. The abscissa in the figure is the frequency (Frequency), the unit is GHz (GHZ), and the ordinate is the return loss parameter (S-Parameter), the unit is dB. From the figure, we can see that there are two troughs, One trough is a GPS band, and the second trough is a WIFI band. It can be seen that the antenna system of the embodiment of the present invention can be a GPS and WIFI two-in-one system.
进一步的,在本实施例提供的天线***中,第二金属走线3的尺寸可调,第二金属走线3的形状可调,第二金属走线3与第一金属走线2的间距可调。Further, in the antenna system provided in this embodiment, the size of the second metal trace 3 is adjustable, the shape of the second metal trace 3 is adjustable, and the distance between the second metal trace 3 and the first metal trace 2 is Adjustable.
具体而言,第二金属走线3可以进行调整,如可调GPS金属走线301和可调WIFI金属走线302即可通过对第二金属走线3的形状进行调整得到,而通过调整第二金属走线3的尺寸,可以实现对天线谐振频率的调整,同样通过对第二金属走线3和第一金属走线2的间距进行调整不仅可以调整天线谐振频率,也可以调整天线的辐射方向。Specifically, the second metal trace 3 can be adjusted, for example, the adjustable GPS metal trace 301 and the adjustable WIFI metal trace 302 can be obtained by adjusting the shape of the second metal trace 3, and The size of the two metal traces 3 can adjust the resonant frequency of the antenna. Similarly, by adjusting the spacing between the second metal trace 3 and the first metal trace 2, the antenna resonance frequency can be adjusted, and the radiation of the antenna can also be adjusted. direction.
可以理解的是,第二金属走线3和第一金属走线2的具体形状均不受限于图3以及图6的绘制。It can be understood that the specific shapes of the second metal trace 3 and the first metal trace 2 are not limited to the drawing of FIG. 3 and FIG. 6.
在实际应用中,基于GPS和WIFI组合天线***,以图5中第一金属走线2和第二金属走线3相对于全金属后盖1的位置与形状为例,本实施例中GPS频段的表面电流主要分布于第一金属走线2靠近馈电点101的右侧,以及第二金属走线3的右侧边缘回形走线部分的内侧,即可调GPS金属走线301。因此,通过调节可调GPS金属走线301的尺寸可以调整GPS天线的谐振频率,调整该可调GPS金属走线301的形状和位置以及距离第一金属走线1的间距,可以调节GPS天线的辐射方向,具体的,GPS天线可覆盖GPS(全球定位***)、GLONASS(全球导航卫星***)、Galileo Positioning System(伽利略定位***)
和北斗等导航***的频段。In practical applications, based on the GPS and WIFI combined antenna system, taking the position and shape of the first metal trace 2 and the second metal trace 3 relative to the all-metal back cover 1 in FIG. 5 as an example, the GPS frequency band in this embodiment The surface current is mainly distributed on the right side of the first metal trace 2 near the feed point 101, and the inner side of the right side edge of the second metal trace 3, and the GPS metal trace 301 can be adjusted. Therefore, by adjusting the size of the adjustable GPS metal trace 301, the resonant frequency of the GPS antenna can be adjusted, the shape and position of the adjustable GPS metal trace 301 and the distance from the first metal trace 1 can be adjusted, and the GPS antenna can be adjusted. Radiation direction, specifically, GPS antenna can cover GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo Positioning System (Galileo Positioning System)
And the frequency band of the navigation system such as Beidou.
同样以图5中第一金属走线2和第二金属走线3相对于全金属后盖1的位置与形状为例,本实施例中WIFI频段的表面电流主要分布在第一金属走线2靠近馈电点101的左侧侧,以及第二金属走线中回形走线部分的左侧,即可调WIFI金属走线302。因此,通过调节可调WIFI金属走线302的尺寸和形状可以调整WIFI天线的谐振频率,具体地,WIFI天线可以覆盖2.4GHZ频段。Taking the position and shape of the first metal trace 2 and the second metal trace 3 relative to the all-metal back cover 1 in FIG. 5 as an example, the surface current of the WIFI band in the present embodiment is mainly distributed on the first metal trace 2 The WIFI metal trace 302 can be adjusted near the left side of the feed point 101 and the left side of the trace line portion of the second metal trace. Therefore, the resonant frequency of the WIFI antenna can be adjusted by adjusting the size and shape of the adjustable WIFI metal trace 302. Specifically, the WIFI antenna can cover the 2.4 GHz band.
进一步的,还是以图5中第一金属走线2和第二金属走线3相对于全金属后盖1的位置与形状为例,该天线***反射单元的表面电流主要分布于馈电点101、第一金属走线2以及第二金属走线3对应的全金属后盖1位置区域,说明了全金属后盖1作为天线***的参考地是本天线***的重要组成部分。同时,由于大部分的辐射能量集中在此区域,而用户在使用移动终端过程中较少接触上述区域,因此可以减少用户对天线***造成的辐射损耗,从而提高天线***的辐射性能。Further, taking the position and shape of the first metal trace 2 and the second metal trace 3 in FIG. 5 relative to the all-metal back cover 1 as an example, the surface current of the reflective unit of the antenna system is mainly distributed at the feed point 101. The position area of the all-metal back cover 1 corresponding to the first metal trace 2 and the second metal trace 3 indicates that the all-metal back cover 1 is an important component of the antenna system as a reference ground for the antenna system. At the same time, since most of the radiant energy is concentrated in this area, and the user is less likely to contact the above area during the use of the mobile terminal, the radiation loss caused by the user to the antenna system can be reduced, thereby improving the radiation performance of the antenna system.
本实施例中,第二金属走线3的尺寸、形状以及与第一金属走线2的间距均可灵活调整,使得天线可以覆盖于若干频段,并可同时工作在低频频段和高频频段,如GPS频段和WIFI频段,得到组合天线***,不仅能够降低天线***对于移动终端全金属后盖的结构设计要求,还可以满足未来移动终端各种网络制式的性能需求。同时,通过对第二金属走线3进行调整,可以满足天线的高性能和方向性可调整的需求,并显著提高调整天线谐振频率的灵活,使得该天线***具有非常好的可实现性和可量产性。In this embodiment, the size and shape of the second metal trace 3 and the distance from the first metal trace 2 can be flexibly adjusted, so that the antenna can cover a plurality of frequency bands and can work in the low frequency band and the high frequency band at the same time. For example, the GPS band and the WIFI band, the combined antenna system can not only reduce the structural design requirements of the antenna system for the all-metal back cover of the mobile terminal, but also meet the performance requirements of various network standards of the mobile terminal in the future. At the same time, by adjusting the second metal trace 3, the high performance and directionality of the antenna can be adjusted, and the flexibility of adjusting the resonant frequency of the antenna is significantly improved, so that the antenna system has very good achievability and Mass production.
