[0027] 从上述描述可知,本实用新型的有益效果在于:提供了一种适用于基于金属外壳的设备中应用的天线结构,且由于天线的辐射元件是沿着边框的侧壁设置的,因此当其应用于便携式设备中时,可支持边框面积内配备更大的显示屏。 [0027] From the above description, the present invention is advantageous effect in that: there is provided an apparatus suitable for an antenna structure based on the application of the metal case, and because the antenna radiating element is provided along the side walls of the frame, thus when applied to a portable device which may be supported within the frame area with a larger display. 此外由于天线的基体元件直接包括平面和边框,因此天线的辐射元件还可作为外壳或直接与便携式设备的外壳一体成型。 Moreover since the base member comprises a planar antenna and a frame directly, thus radiating antenna element can also serve as a housing or directly molded integrally with the housing of the portable device.

[0028] 实施例1 : [0028] Example 1:

[0029] 上述结构中,所述辐射元件的第一天线分支包括依次相连的第一坚直部,第一水平部、第二坚直部、第二水平部B及第三坚直部;所述第一坚直部端部为第一地端,第三坚直部端部为馈电端;所述第二水平部B连接第三坚直部处还连接第二天线分支。 [0029] In the above configuration, the first branch of the radiating antenna element comprises a first straight portion firmly connected in sequence, a first horizontal portion, a second straight portion Kennedy, second horizontal portions B and the third straight portion Kennedy; the Kennedy said first straight portion to a first end of the end portion, the third straight portion Kennedy feeding terminal end portion; B of the second horizontal portion connected at a third straight portion Kennedy also connected antenna branch. 通过该结构,可提供一种很好的折叠结构,使得环形的第一天线分支在较小空间中得以放置。 With this configuration, it may provide a good folding structure, such that a first loop antenna branch is placed in a smaller space.

[0030] 最佳的,第二天线分支也包括第三水平部A,由此第二天线分支的第三水平部A可与第一天线分支的第二水平部B连接并延伸,形成一个规则的形状,便于生产。 [0030] The optimal antenna branch A also includes a third horizontal portion, whereby the second antenna branch A third horizontal portion may be connected to the first antenna branch and extending a second horizontal portion B, forming a regular shape, ease of production.

[0031] 实施例2: [0031] Example 2:

[0032] 上述结构中,所述第一天线分支的第二水平部B与第一坚直部、第一水平部、第二坚直部、第三坚直部位于不同平面上。 [0032] In the above configuration, the first antenna branch of the second horizontal portion B of the first straight portion Kennedy, the first horizontal portion, a second straight portion Kennedy, Kennedy third straight portion located on different planes.

[0033] 本实施例中,通过将第一天线分支第二水平部B弯折至与其他与第一坚直部、第一水平部、第二坚直部、第三坚直部位于不同平面上(最佳的弯折成与基体元件的平面相平行的方向),从而使得在合理的结构下天线整体的高度得以最大程度缩减。 [0033] In this embodiment, unlike other to bend the straight portion of the first strong, the first horizontal portion, a second straight portion Kennedy, Kennedy third straight portion lies in a plane through the second horizontal portion of the first antenna branch B (the direction of the plane bent best with the base element parallel), so that the entire height of the antenna is reduced in the maximum extent reasonable structure.

[0034] 实施例3 : [0034] Example 3:

[0035] 与上述实施例不同的是,本实施例中,第一天线分支的第一坚直部,第一水平部、 第二坚直部、第二水平部B及第三坚直部处于同一平面上,且第一坚直部,第一水平部、第二坚直部、第二水平部B的总高度不大于边框高度。 [0035] The above-described embodiment except that, in this embodiment, the first straight portion of the first Kennedy antenna branches, the first horizontal portion, a second straight portion Kennedy, second horizontal portions B and the third straight portion in firm on the same plane, and the first straight portion Kennedy, the first horizontal portion, a second straight portion Kennedy, the total height of the second horizontal portion B is not greater than the border height. 如图2所示,此种结构省去了弯折水平部的麻烦,但整体天线的高度会增加,因此适合较边框较高的结构中应用。 2, such a configuration eliminates the trouble of the horizontal bent portion, but the overall height of the antenna is increased, and therefore more suitable for higher frame structure applications.

[0036] 实施例4 : [0036] Example 4:

[0037] 上述结构中,所述第三天线分支包括依次连接的第四坚直部及第四水平部C;所述第四坚直部端部为第二地端73,第二地端73与基体元件的平面61电连接;所述第四水平部C与第一天线的第二水平部B间隔设置。 [0037] In the above configuration, the third antenna comprises a fourth branch connected sequentially Kennedy straight portion and the fourth horizontal portion C; Kennedy straight portion of the fourth end portion to a second end 73, a second end 73 to plane 61 is electrically connected to the base member; a second horizontal portion B spaced from said fourth horizontal portion C and the first antenna.

[0042] 本实施例中,所述馈电端与基体元件的平面间通过匹配电路电连接。 [0042] In this embodiment, the plane between the feeding terminal and electrically connected to the base element via a matching circuit.

[0043] 如图5、6中虚线所示为天线的A,B和C的长度值被用于优化双波段无线WIFI的2. 4&5GHz但不搭配任何匹配电路情况下的S11回波损耗特性图。 [0043] As shown in dashed lines 5 and 6 as lengths A, B and C are used to optimize antenna is a dual-band wireless WIFI 2. 4 & 5GHz, but not with the S11 return loss characteristics of the matching circuit in any case . 从图5看出,虽然此时的天线不适合在WiFi低频段(即WiFi2. 4G)工作,但可以很好地用于了WiFi高频段(既WiFi5G)。 Seen in Figure 5, although in this case the antenna is not suitable (i.e. WiFi2. 4G) operating in a WiFi low frequency band, but can be well used in the high frequency band WiFi (both WiFi5G). 进一步的,如图5、6中的实线所示为在天线馈电端口串联了匹配电路后的情况, 可见天线满足了WIFI低频带的要求且最重要其无线高频带的性能不被削弱。 Further, as shown in solid lines in FIG. 5 and 6 for the antenna feed port in the case where the series matching circuit, an antenna can be seen to meet the requirements of low band WIFI and its most important high-band wireless capability is not impaired . 因此,当需要更好的兼容WIFI高频和低频时,可在天线的馈电端与基体元件间增加匹配电路(最常见的匹配电路即串联一个电感),由此使得最终的天线的第一共振是在2. 45GHz,而天线的第二个和第三共振是在4. 98GHz和5. 68GHz。 Thus, when a need for better compatibility WIFI high and low frequency, the matching circuit may be added between the substrate and the power feeding terminal of the antenna element (the most common matching circuit i.e. a series inductor), whereby the first antenna such that the final resonance is 2. 45GHz, while the second and third resonant antenna is to 4. 98GHz and 5. 68GHz. 如图7所示可以看出,天线的阻抗带宽-6dB时的水平覆盖低频带从2. 39到2. 52GHz和高频带从4. 87到5. 94GHz,表明该天线可以完全支持两个无线2. 4GHz和无线5GHz的。 As shown in FIG 7 can be seen, when the level of impedance bandwidth of the antenna covers a low band -6dB from 2.39 to 2. 52GHz and the high band is from 4.87 to 5. 94GHz, indicating that the antenna can support two full 2. 4GHz and 5GHz wireless radio of.

[0044] 实施例7 : [0044] Example 7:

[0045] 上述结构中,所述第一天线总长度与5G WIFI的头一个谐振(4. 98GHz左右)的1/2 波长相等,其可以被看作是一个环行类型的天线。 [0045] The above-described configuration, the total length of the first antenna and the head of a resonant 5G WIFI (about 4. 98GHz) is equal to 1/2 wavelength, which can be viewed as a type of antenna circulator.

[0046] 所述第二天线端部至馈电端总长度与2. 4G WIFI的谐振(2. 45GH在左右)的1/4 波长相等; [0046] The end portion of the second antenna to the feeding end of the total length of 2. 4G WIFI resonance (2. 45GH about) equal to a quarter wavelength;

[0047] 所述第三天线端部至基体元件的平面的总长度与5G WIFI的第二个谐振(5. 68GHz 左右)的1/4波长相等,其可以被看作是一种寄生元件。 The [0047] third antenna element to the base end portion of the overall length of the plane of the second resonant 5G WIFI (about 5. 68GHz) equal to 1/4 wavelength, which may be regarded as a parasitic element.

[0048] 符合上述条件后,本天线可完全适用于2. 4G及5G的WIFI双频WIFI天线使用。 [0048] After it meets the above criteria, the present antenna may be fully applicable to dual-band WIFI antenna 2. 4G and 5G WIFI use. 具体地说,该设计双频无线网络2. 4、5GHz的天线应包括以下频段: In particular, the dual-band wireless network antenna design 2. 4,5GHz band shall include the following:

[0049] 1)、低频段的WiFi :2. 4-2. 48GHz 的(无线2. 4GHz 网络); [0049] 1), low frequency WiFi: 2 4-2 48GHz (radio network 2. 4GHz);.

[0050] 2)、高频段的WiFi :4. 9-5. 9GHz 的(无线5GHz 的网络)。 [0050] 2), WiFi high frequency:.. 4 9-5 9GHz (the 5GHz wireless network).

[0051] 本天线设计时,考虑到虽然一个谐振即可支持上述低频段的WiFi,但对于高频段的WiFi而言因为其所需带宽较宽,通常需要两个谐振。 [0051] The present antenna design, taking into WiFi While a resonator to support the low-frequency band, but for the high frequency band as it WiFi desired wide bandwidth, typically requires two resonators. 换言之,要同时支持双频段2. 4、 5GHz的WIFI,则天线应具有三个谐振,一个用于低频带,两用于高频段。 In other words, to support dual-band WIFI 2. 4, 5GHz, the antenna should have three resonance, a low frequency band is used, two for the high frequency band. 因此,在本实施例中,第一天线是配合5G的第一个谐振、而第二天线则配合2. 4G的谐振、第三天线适应5G的第二个谐振的。 Accordingly, in the present embodiment, the first antenna is resonant with the first 5G, the second antenna is a complex resonance 2. 4G, 5G third antenna adaptation second resonance. 进一步的,由于天线自身是设置在金属的边框上的(即主要位于金属侧壁上),实际上天线的辐射元件甚至直接可以由金属侧壁一部分制成,因此不像往常金属外壳的天线设计,本专利并不需要制造一个单独的辐射元件后配置,生产上效率更高。 Further, since the antenna is provided on the frame itself metals (i.e., primarily on the metal side wall), in fact, even directly radiating antenna element may be made of a metal side wall portion, so unlike the usual metal housing antenna design after, this patent does not require a separate manufacturing a radiating element disposed higher production efficiency.

[0052] 本专利方案中,辐射元件的每个天线尺寸可根据共振需求来调整,但最佳是调整图1中的第二水平部A,第三水平部B和第四水平部C的值。 [0052] The present patent, each radiating element of the antenna size can be adjusted according to the needs of the resonator, but the best is to adjust the value of the second horizontal portion in FIG. 1 A, B and the third horizontal portion of the fourth horizontal portion C .

[0053] 此处进一步说明如何将天线上述的A,B和C的值进行调整。 [0053] Here will be further explained how to adjust the value of the antenna A, B and C described above. 天线中A、B、C的S11 的变化可参见图8、9、10。 S11 changes the antenna A, B, C 8,9, 10 can be seen in FIG. 如图8可以看出,第一谐振和第三共振会由于A的长度变化而发生显著变化,这表明,天线的第一和第三谐振可以通过参数A进行调整。 As it can be seen in FIG. 8, the first resonator and the third resonator length can vary significantly due to a change A occurs, which indicates that the first and third resonance antenna can be adjusted by the parameters A. 而图9中,只有天线的第二谐振受B的影响。 And FIG. 9, only the influence of the second resonance B-receiving antenna. 图10所示的结果表明,C的值主要是控制第三谐振。 The results shown in Figure 10 shows that the value of C is mainly controlling the third resonance. 因此,通过梳理上述测试结果可以得出结论,第二谐振可以通过B的值进行控制的,该第三谐振可以主要通过调节C的值,并且所述第一谐振能由A的值进行调整。 Thus, it can be concluded by combing the above test results, the second resonance may be, the third resonance by adjusting a value C may be primarily controlled by the value B, and the first resonator can be adjusted by a value A.

[0054] 在本实用新型中,环形的第一天线分支是必不可少的,因为它是用于产生频率在5GHz左右的第二谐振的。 [0054] In the present invention, the first loop antenna branch is essential, because it is used to generate a second resonant frequency of about 5GHz. 第一天线成分支为一个环形天线为元件的条件是: Conditions for the first branch into a loop antenna for the antenna elements are:

[0055] 1)第一天线分支的长度必须足够长; [0055] 1) a first antenna branch length must be long enough;

[0056] 2)在同一时间,当第一天线分支长度变化时,其第一地端和馈电端之间的距离必须保持在小范围内变化(或没有变化)。 [0056] 2) At the same time, when the change in length of the first antenna branch, the distance between a first end and a feeding terminal must be kept within a small range of change (or not change). 当第一天线分支作为环形天线工作时,第二天线分支仅作为一种单极天线,而不是作为IFA类天线即使它的馈电端和第一地端彼此靠的较近。 When the first loop antenna as an antenna branch, the second antenna as a monopole antenna branch only, and not as an antenna even if it is based IFA feeding terminal and a first ground end close against each other. 但是,如果在天线的馈电端串联了匹配电路,则第二天线分支将成为IFA型天线即使第一天线分支仍然作为环形天线。 However, if the series matching circuit at the feed end of the antenna, the second antenna branch will become IFA antenna remains even when the first antenna branch as a loop antenna. 当第二天线分支不作为IFA天线工作时,其产生的谐振的性能(例如,在围绕WiFi2. 4GHz的范围内)是非常差的(见图5中所示的围绕2. 4GHz的虚线);然而,当匹配电路连接在馈电端后,围绕第二天线分支创建的2. 4GHz的性能可显著改善(见图5中所示的围绕2. 4GHz的实线)。 When the second antenna branch is not taken as an IFA antenna, performance of which produces resonance (for example, in the range of about WiFi2 4GHz) is very poor (see dashed lines around the 2. 4GHz shown in Figure 5); However, when the matching circuit is connected to the feeding end, about the performance of the second antenna branch is created 2. 4GHz significantly improved (see the solid line shown around the 2. 4GHz. 5).

[0057] 实施例8 : [0057] Example 8:

[0058] 上述结构中,所述辐射元件的外尺寸与边框间隔l_2mm。 [0058] The above-described configuration, the outer dimension of the radiating element and the frame interval l_2mm.

[0059] 不论天线中A、B、C怎么调整,其与边框的缺槽63的壁之间的间隙始终保持为GAP =1-2_,由此,保持不变的间隙也意味着与金属边框协同设计的天线的尺寸可以始终保持为其最小。 [0059] Regardless of antennas A, B, C how to adjust the gap between the walls with the frame notched groove 63 is always maintained GAP = 1-2_, thereby maintaining constant the gap with the metal frame means size of the antenna collaborative design can always maintain its minimum.

[0060] 本实用新型还涉及一种便携式设备,如图4所示。 [0060] The present invention further relates to a portable device, as shown in FIG. 它包括外壳,框架及显示屏。 It comprises a housing, a frame and a display screen. 其中,外壳主要包括金属面壳、金属边框及如上所述的双频段WIFI天线组成。 Wherein the housing comprises a dual-band WIFI antenna main metal shell, the metal frame and the composition as described above. 所述双频段WIFI天线的辐射基体元件嵌套于所述框架内。 The dual-band WIFI antenna radiating element is nested within the base of the frame.

[0062] 综上所述,本实用新型提供的双频段WIFI天线,通过在设备的金属边框侧壁上设置天线的方法,不仅确保了天线可在此种环境(例如基于金属外壳的条件)下正常工作,且使得其搭配显示屏使用时,由于设备的上表面没有布置大面积的天线辐射体,使显示屏与金属外壳的边缘间的间隙可以比现有设计小很多,从而确保了同体积下最大限度的屏幕搭载需求。 [0062] In summary, the present invention provides a dual-band WIFI antenna, through an antenna provided on the side wall of the metal frame apparatus and method which not only ensures the antenna under such an environment (e.g., conditions based on the metal shell) work, and that it used with the display screen, since the upper surface of the device without the large antenna radiator is arranged, the gap between the edge of the display and the metal housing can be much smaller than the conventional design, ensuring that the same volume under the maximum screen equipped with demand. 此外,由于天线是设置在边框的侧壁上,且进一步可由边框的一部分制成,因此不同于其他天线设计,无需额外配备天线的辐射元件,该天线可以容易地和金属外壳一体制造。 Further, since the antenna is disposed on the side wall of the frame, and further may be formed as part of the border, so different from the other antenna designs, no additional radiating element is equipped with an antenna, the antenna can be easily manufactured in one piece and the metal housing.
