Description
通信终端天线及通信系统 技术领域 本发明涉及通信领域， 具体涉及一种通信终端天线及通信系统。 背景技术 目前在智能手机越做越轻薄， 尤其是厚度小于 7-8mm的情况下， 在拥挤的结构中 设计工作良好的全球定位系统（Global Position System, 简称为 GPS)天线和近距离无 线通信 （Near Field Communication, 简称为 NFC) 天线对于射频和结构工程师是极大 的挑战。 手机所用天线例如倒 F型天线 （Inverted-F Antenna, 简称为 IFA)、 平面倒 F 型天线 （ Planar Inverted-F Antenna, 简称为 PIFA)、 单极天线 （monopole)等类型都需 要较为良好的离地距离或者净空， 一般来说以离地高度为 6.5mm以上为佳， 而在手机 天线布局结构主要满足 3G和长期演进（Long-Term Evolution, 简称为 LTE)分集和无 线保真 （Wireless Fidelity, 简称为 WiFi) /蓝牙 （Bluetooth, 简称为 BT) 等主要通讯 需求的情况下， 很难有很好的空间结构留给 GPS或者 NFC等较少使用的无线模块。 通信终端用 GPS模块对于接收灵敏度要求极高， 目前初始灵敏度可达 147dBm， 这样 就使很多智能手机的 GPS接收性能不佳，搜索较慢甚至很难冷启动从而影响了用户体 验。 而 NFC天线由于工作于 13.56MHz频段， 其使用的磁性耦合线圈天线的大小受到 很大限制， 尺寸较大而不易缩小， 比如三星 galaxy nexus手机设计中不得已将 NFC天 线设计到了电池上， 这样的设计需要使用昂贵的铁氧体材料来降低金属材料对于信号 磁场的吸收， 以降低干扰。 同时由于手机内部结构复杂， 影响因素很多， 需要花费大 量的时间人力用于调试天线的频率以保证工作正常， 使用成本高。 而如果将天线布置 在较为靠近外壳边缘或者使用金属外壳边框作为手机天线， 如 iph0ne4和 iph0ne4s等 设计， 在用户手直接握持时， 手机天线接地点也会收到较大的影响， 从而严重影响射 频性能。 可见， 在智能手机越做越轻薄的今天， 将天线设置在手机终端内部存在可用 空间少、 成本高、 难设计且易受到干扰的问题。 发明内容 本发明实施例要解决的主要技术问题是， 提供一种通信终端天线及通信系统， 解 决现有天线设计面临的可用空间少、 成本高、 设计难且易受到干扰的问题。
为解决上述技术问题， 本发明实施例提供一种通信终端天线,所述通信终端天线为 外置天线， 包括从上往下依次设置的第一保护层、 第三保护层， 以及设置于所述第一 保护层与所述第三保护层之间的天线主体；还包括与所述天线主体连接的天线连接件， 所述天线主体通过所述天线连接件与通信终端连接。 在本发明的一种实施例中， 所述第三保护层的底面设有连接件， 所述通信终端天 线通过所述连接件与所述通信终端可拆卸连接。 在本发明的一种实施例中， 所述第一保护层的上表面设有清洁层。 在本发明的一种实施例中， 所述连接件为多次可贴胶层。 在本发明的一种实施例中， 所述天线主体为 NFC天线主体或 GPS天线主体。 在本发明的一种实施例中， 所述天线主体为平面天线主体。 在本发明的一种实施例中， 所述通信终端天线还包括设置于所述第一保护层和所 述第三保护层之间的第二保护层， 所述第二保护层围合在所述天线主体周围。 为了解决上述技术问题， 本发明还提供了一种通信系统， 包括通信终端和如上所 述通信终端天线， 所述通信终端上设有馈电接口或馈电用触点， 所述通信终端天线通 过所述天线连接件与所述馈电接口或馈电用触点连接。 在本发明的一种实施例中， 所述通信终端为手持通信终端， 所述馈电接口设置在 所述通信终端背面。 在本发明的一种实施例中， 所述馈电接口为射频馈电接口。 在本发明的一种实施例中， 所述通信终端天线固定在所述通信终端背面。 本发明实施例的有益效果是： 本发明实施例提供了通信终端天线及通信系统，其中，将通信终端的天线设置在 通信终端的外部， 作为外置天线， 该天线具体包括从上往下依次设置的第一保护层、 第三保护层， 以及设置于第一保护层与第三保护层之间的天线主体； 还包括天线连接 件， 天线主体通过所述天线连接件与通信终端连接。 可见， 本发明提出了将天线外设 在通信终端上的方案， 由于将天线外设， 因此可以解决将天线设置在终端内部面临的 可用空间不足的问题， 能很好的解决通信终端天线与超薄结构设计的矛盾和设计困难 的问题， 降低设计及使用成本； 同时， 将天线设计在通信终端外部， 使其与终端内部
的电路板以及电池等分离， 可降低对天线的干扰， 提高其性能， 进而提高用户体验的 满意度。 附图说明 图 1为本发明一种实施例的通信终端天线结构示意图； 图 2为本发明一种实施例的另一种通信终端天线结构示意图； 图 3为图 2所示通信终端天线组合后的结构示意图； 图 4为本发明一种实施例的通信终端天线设置在通信终端上的结构示意图。 具体实施方式 下面通过具体实施方式结合附图对本发明作进一步详细说明。 本实施例中的通信终端天线为通信终端的外置天线， 其可通过可拆卸的方式与通 信终端连接。 请参见图 1所示， 该通信终端天线包括从上往下依次设置的第一保护层 1、 第三保护层 3， 以及设置于第一保护层 1与第三保护层 3之间的天线主体 2， 还包 括与天线主体 2连接的天线连接件（图中未示出），天线主体 2通过天线连接件与通信 终端有效连接。 具体的， 天线连接件可通过终端上设置的馈电用触点或馈电接口与通 信终端进行有效连接。 馈电接口的设置方式射频馈电接口。 由于本实施例中将天线外设在通信终端上， 因此可以解决将天线设置在终端内部 面临的可用空间不足的问题， 能很好的解决通信终端天线与超薄结构设计的矛盾和设 计困难的问题， 降低设计及使用成本； 同时， 将天线设计在通信终端外部， 可使其与 终端内部的电路板以及电池等分离， 可降低对天线的干扰， 提高其射频性能， 可提高 用户体验的满意度。 本实施例中可在第三保护层 3的底面设置连接件， 通信终端天线可通过该连接件 与通信终端可拆卸连接。 由于通信终端天线与通信终端可拆卸连接， 因此用户可在使 用时才将其与通信终端连接， 不使用时， 则可将其拆卸下来另外放置。 用户使用更方 便， 可进一步提高用户体验的满意度。 优选的， 本实施例中在第三保护层 3的底面设 置的连接件可以是多次可贴胶层， 用户在使用时， 可直接将其贴在通信终端上的相应 位置。 目前的多次粘贴技术已经比较成熟， 能轻易做到无残留和长期保持粘性。 连接 件除了采用多次可贴胶层外， 还可采用其他可拆解结构， 例如设置为卡接 （需在终端 上设置对应的卡接装置） 等。
进一步的， 本实施例还可在第三保护层 3的底面设置定位件， 用于在将通信终端 天线与通信终端连接的过程中起到定位作用。 该定位件具体可设置为定位卡扣或凹凸 件， 对应的， 在通信终端上需设置对应的定位装置。 在本实施例中， 还可在第一保护层 1的上表面设置清洁层， 该清洁层可采用吸尘 材料或防水材料制成。 同时， 还可在该清洁层上印刷装饰图案或用户自定义的图案。 由于通信终端天线可拆卸的连接在通信终端上， 且在第一保护层 1上设置清洁层， 因 此用户可将固定在通信终端上的通信终端天线拆下来作为屏幕擦拭布使用， 非常使用 于大屏幕的通信终端， 例如智能手机、 IPAD等通信终端。 本实施例中，天线主体 2可为 NFC天线主体或 GPS天线主体，也可同时作为 NFC 天线主体或 GPS天线主体使用。 其中， 天线主体 2可优选为平面天线主体。 当天线主 体为 NFC天线主体时， 可采用具有磁性的 FPC (柔性电路板） 组成； 当天线主体为 GPS天线主体时， 则可采用 FPC或蚀刻金属薄片组成。 为了进一步增加安全性能， 请参见图 2和图 3所示， 本实施例中的通信终端天线 还可进一步包括第二保护层 4， 第二保护层 4围合在天线主体周围.其可采用硅胶、 软 塑料等具有弹性的材料。 应当理解的是， 本实施例中的第一保护层 1、第二保护层 3、第三保护层 4以及天 线主体的形状处理可设置为平面外， 还可根据实际情况选择设置为其他形状。 例如可 将第一保护层 1、第二保护层 3、第三保护层 4以及天线主体 2组装后形成的通信终端 天线的形状设置为与通信终端相匹配的形状， 因而可作为保护终端保护套使用。 对于 其他形状的设置方式， 本实施例中则不再进行赘述。 下面仍以设置为平面状， 可作为屏幕擦拭布使用进行说明。 请参见图 4所示， 使用时， 将通信终端天线 5通过第三保护层 3底面上设置的连 接件 （例如多次可贴胶） 固定在通信终端 6 (例如手机、 IPAD等） 上， 并通过天线连 接件与通信终端 6连接。 本实施例中， 通信终端 6上的馈电接口或馈电用触点设置在 背面， 优选设置在通信终端 6背面设置有电池的区域。 通信终端 6外部的通信终端天 线 5工作时， 其内部的天线断开。 当然， 采用本发明提供的方案， 通信终端 6内部也 可不再额外设置天线。 由于目前大屏手机等智能终端后盖电池部位上部有很大的空间 （>40x50mm) , 天线设置在后盖外部， 距离印刷电路板 （Printed Circuit Board, 简称为 PCB) 和电池 参考地面就有足够的高度 >6.5mm， 也隔绝了手机内部的干扰， 可以得到很好的射频
性能。 同时， 由于手机后盖电池上面区域由于人体工程学的握法规律， 用户的手部接 触可能较小， 这样用户使用过程中触碰到外置的通信终端天线导致干扰天线工作的几 率较小， 这样使得手机的 GPS和 NFC无线通讯模块也避免了受到用户手部接触天线 部分所带来的性能下降的问题。 可见， 本发明将通信终端天线外置， 从而不占用通信终端的内部空间， 使通信终 端内部的应用空间得到很大的提升； 并且， 能够使通信终端的天线远离其内部的 PCB 板以及电池的干扰； 另外， NFC或者 GPS天线的尺寸和形状不也再受制于通信终端内 部可利用空间的限制。 为了更明确的说明， 下面结合大屏幕手机为例进行说明： 大屏幕手机内部 GPS天线一般可用面积仅为 15x10mm以下， 还要受到周围电子 元器件摆放的干扰，而本实施例的外置天线面积可达到 50x40mm以上， 由于天线性能 的很大部分取决于天线面积， 很显然本实施例的天线具有更好的性能。对于 NFC或者 其他近场通讯天线， 由于其工作频段更低为 13.56MHz, 如果设计在手机内部， 势必需 要更大面积， 如设计在面积较大的电池上方则需要使用昂贵的铁氧体材料来降低金属 材料对于信号磁场的吸收， 成本较高； 同时由于手机内部结构复杂， 影响因素很多， 需要花费大量的时间人力用于调试天线的频率以保证工作正常， 而本实施例的天线粘 贴于手机后盖外部， 隔绝了通讯终端内部的干扰因素， 因此设计和调试都非常方便， 可用天线面积充裕， 无需采用昂贵的铁氧体材料， 还可降低成本。 同时， 本实施例中 的天线还可灵活的设置为屏幕擦或手机保护壳， 不会给用户造成其他的突兀感， 且更 便于用户的使用， 能进一步提高用户体验的满意度。 以上内容是结合具体的实施方式对本发明所作的进一步详细说明， 不能认定本发 明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员来说， 在 不脱离本发明构思的前提下， 还可以做出若干简单推演或替换， 都应当视为属于本发 明的保护范围。

In addition to multiple adhesive layers, the connector can also be used with other detachable structures, such as a card (which requires a corresponding snap-on device on the terminal). Further, in this embodiment, a positioning component may be disposed on the bottom surface of the third protective layer 3 for positioning in the process of connecting the communication terminal antenna and the communication terminal. The positioning member may be specifically configured to position a buckle or a concave and convex member, and correspondingly, a corresponding positioning device is disposed on the communication terminal. In the present embodiment, a cleaning layer may also be disposed on the upper surface of the first protective layer 1, and the cleaning layer may be made of a vacuuming material or a waterproof material. At the same time, a decorative pattern or a user-defined pattern can also be printed on the cleaning layer. Since the communication terminal antenna is detachably connected to the communication terminal, and the cleaning layer is disposed on the first protection layer 1, the user can remove the communication terminal antenna fixed on the communication terminal and use it as a screen wiping cloth, which is very used for large A communication terminal of a screen, such as a communication terminal such as a smart phone or an IPAD. In this embodiment, the antenna main body 2 may be an NFC antenna main body or a GPS antenna main body, or may be used as an NFC antenna main body or a GPS antenna main body at the same time. The antenna body 2 may preferably be a planar antenna body. When the antenna body is an NFC antenna body, a magnetic FPC (flexible circuit board) may be used; when the antenna body is a GPS antenna body, an FPC or an etched metal foil may be used. In order to further improve the security performance, as shown in FIG. 2 and FIG. 3, the communication terminal antenna in this embodiment may further include a second protection layer 4, and the second protection layer 4 is enclosed around the antenna body. , flexible materials such as soft plastic. It should be understood that the shape processing of the first protective layer 1, the second protective layer 3, the third protective layer 4, and the antenna body in this embodiment may be set to be out-of-plane, and may be selected to be other shapes according to actual conditions. For example, the shape of the communication terminal antenna formed by assembling the first protective layer 1, the second protective layer 3, the third protective layer 4, and the antenna main body 2 can be set to match the shape of the communication terminal, and thus can be used as a protective terminal cover. use. For other shapes, the description will not be repeated in this embodiment. The following is still set to a flat shape and can be used as a screen wiper. Referring to FIG. 4, in use, the communication terminal antenna 5 is fixed on the communication terminal 6 (for example, a mobile phone, an IPAD, etc.) through a connector (for example, a plurality of adhesives) provided on the bottom surface of the third protective layer 3, and It is connected to the communication terminal 6 through an antenna connector. In the present embodiment, the feed interface or the feed contact on the communication terminal 6 is provided on the back side, and is preferably provided in a region where the battery is provided on the back surface of the communication terminal 6. When the communication terminal antenna 5 outside the communication terminal 6 operates, the antenna inside thereof is disconnected. Of course, with the solution provided by the present invention, the antenna may not be additionally provided inside the communication terminal 6. Since there is a large space (>40x50mm) on the upper part of the rear cover of the intelligent terminal such as a large-screen mobile phone, the antenna is disposed outside the back cover, and there is enough distance from the printed circuit board (PCB) and the battery reference ground. The height is >6.5mm, which also isolates the internal interference of the mobile phone and can get a good RF. Performance. At the same time, due to the ergonomic grip law of the upper area of the back cover battery of the mobile phone, the user's hand contact may be small, so that the user touches the external communication terminal antenna during use, which causes the interference antenna to work less. This allows the GPS and NFC wireless communication modules of the mobile phone to avoid the problem of performance degradation caused by the user's hand touching the antenna portion. It can be seen that the antenna terminal of the communication terminal is externally disposed without occupying the internal space of the communication terminal, so that the application space inside the communication terminal is greatly improved; and the antenna of the communication terminal can be remote from the internal PCB and the battery. Interference; In addition, the size and shape of the NFC or GPS antenna are not limited by the space available within the communication terminal. For a more specific explanation, the following is an example of a large-screen mobile phone: The internal GPS antenna of a large-screen mobile phone generally has an available area of only 15x10 mm or less, and is also interfered by the placement of surrounding electronic components, and the external antenna of this embodiment The area can reach 50x40mm or more. Since a large part of the antenna performance depends on the antenna area, it is obvious that the antenna of this embodiment has better performance. For NFC or other near field communication antennas, because the working frequency band is lower at 13.56MHz, if it is designed inside the mobile phone, it is bound to need a larger area. If it is designed on a larger battery, it needs to use expensive ferrite material. Reducing the absorption of the signal magnetic field by the metal material is costly; at the same time, due to the complicated internal structure of the mobile phone, there are many influencing factors, and it takes a lot of time and manpower to debug the frequency of the antenna to ensure normal operation, and the antenna of the embodiment is attached to the mobile phone. The outside of the back cover isolates the interference factors inside the communication terminal, so it is very convenient to design and debug. The available antenna area is sufficient, eliminating the need for expensive ferrite materials and reducing costs. At the same time, the antenna in this embodiment can also be flexibly set as a screen wipe or a mobile phone protective cover, which does not cause other sudden feelings to the user, and is more convenient for the user to use, and can further improve the satisfaction of the user experience. The above is a further detailed description of the present invention in connection with the specific embodiments, and the specific implementation of the invention is not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
