Description

天线结构及应用该天线结构的通信终端
本申请要求于2016年5月28日提交中国专利局、申请号为201610368784.2、发明名称为“天线结构及应用该天线结构的通信终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种天线结构及应用该天线结构的通信终端。
背景技术
车联网标准终端T-Box，是一项面向需求，提升汽车产业经济结构的新兴产品。T-Box通过车规级的处理芯片利用无线通信技术来实现，基于“汽车级”对可靠性、工作温度、抗干扰等方面要求苛刻，主要实现4G远程无线通讯、GPS卫星定位、加速度传感和CAN通讯功能，进而实现车辆远程监控、安全监测和报警、远程诊断等多种在线应用。
T-Box的天线设计，除了要支持具备多模(GSM/WCDMA/LTE)工作制式以外，其可靠性设计非常重要。一般无线终端的使用寿命2～5年，使用环境固定(比如手机常带身边，无线路由器安装在办公室或家中某个固定位置等)，天线设计更多地是集中在如何拓展带宽，缩减天线尺寸方面。而T-Box内置于汽车内，使用寿命要求10年以上，使用环境也比较恶劣。汽车零部件组装差，而汽车行驶过程中不停的颠簸，会造成汽车零部件的松动、脱落，因此，汽车对可靠性的要求非常严格，T-Box内各器件的组装要求必须要达到“汽车级”可靠性标准。传统的通信终端天线制造，把天线划作一个单独模块，它与整机射频模块的集成，一般是通过射频通道在PCB电路板上预留的金属弹脚来连接。汽车长久行驶，颠簸的使用环境，如果T-Box的天线制造还是采用这种方式，必然导致可靠性的风险增大。

具体实施方式
下面将结合附图，对本发明的实施例进行描述。
请一并参阅图1和图2，在本发明一个实施例中，提供一种天线结构10，其可以应用于车联网标准终端T-Box、智能手机、平板电脑等通信终端中，用于发送和接收无线通信信号。在发明实施例中，以所述天线结构10应用于车联网标准终端T-Box中为例进行说明，通过在车联网标准终端T-Box中设置所述天线结构10，以通过所述天线结构10发送和接收无线通信信号，从而实现车辆的远程监控、安全监测和报警、远程诊断等功能。
所述天线结构10包括天线基板11、第一辐射部13和第一插接部15。所述天线基板11包括第一侧边111，所述第一辐射部13设置于所述天线基板11的第一表面113，并包括沿所述第一侧边111设置的第一辐射体131。请参阅图2，所述第一辐射体131相对于所述第一侧边111的一侧设置有多个第一插槽1311。所述第一插接 部15包括插接片151和延伸片153。所述插接片151的一端设置有与所述第一插槽1311相对应的多个第一插头1511，用于将所述插接片151的一端通过所述第一插槽1311连接至所述第一辐射体131；所述插接片151的另一端朝远离所述第一表面113的方向延伸。所述延伸片153的一端与所述插接片151远离所述第一表面113的一端连接，另一端朝向所述第一表面113弯折延伸。可以理解，所述第一插槽1311贯穿所述第一辐射体131并可部分延伸至所述天线基板11内。
在本实施例中，所述天线基板11可以是通信终端的电路板的一部分，且所述天线基板11作为所述天线结构10的净空区，即所述天线基板11上不设置任何电子元器件，以防止电子元器件对所述天线结构10的辐射性能产生影响。所述插接片151与所述第一辐射体13垂直连接，所述延伸片153呈倒“L”型，所述延伸片153一端与所述插接片151连接，另一端沿平行于所述第一表面的方向延伸一段距离后，再朝向垂直于所述第一表面的方向延伸一段距离，从而使得所述第一插接部15整体上呈“U”型结构。
所述天线结构10通过在所述第一辐射部13上设置所述第一插槽1311，并在所述第一插接部15上设置所述第一插头1511，从而可以将所述第一插接部15通过所述第一插头1511插入所述第一插槽1311内，以实现所述天线结构10在垂直于所述第一表面113的方向上的延伸，进而还可以通过焊接的方式将所述第一插接部15焊接至所述第一辐射部13上，以实现所述第一插接部15与所述第一辐射部13之间的稳固连接，提升所述天线结构10各个组成部分之间的稳定性及可靠性。同时，通过在所述第一插接部15上设置所述延伸片153，从而使得所述第一插接部15可以在平行于所述天线基板11的方向上延伸，并可通过弯折处理以实现较小的天线尺寸，从而可以有效降低通信终端内部空间的限制对所述天线结构10的影响，并改善所述天线结构10的低频性能。
在一种可选的实施方式中，所述天线结构10还包括设置于所述天线基板11的第二表面115的第二辐射部17，所述第二表面115与所述第一表面113相对，所述第二辐射部17沿所述天线基板11的第一侧边111设置，并通过多个贯穿所述天线基板11的金属过孔1101与所述第一辐射部13连接。所述第二辐射部17沿所述第一侧边111的一侧设置有的多个第二插槽1711，所述第二插槽1711与所述第一插槽1311交错排布，所述天线结构10还包括第二插接部19，所述第二插接部19的一端设置有与所述第二插槽1711相对应的多个第二插头1911，用于将所述第二插接部19的一端通过所述第二插槽1711连接至所述第二辐射部17，所述第二插接部19的另一端朝向远离所述第二表面115的方向延伸。在本实施例中，所述第二插接部呈“I”型结构。
所述天线结构10通过在所述天线基板11的第二表面115上设置所述第二辐射部17，并在所述第二辐射部17上设置多个第二插槽1711，同时通过设置所述第二插接部19，并在所述第二插接部19的一端设置与所述第二插槽1711对应的第二插头1911，从而可以将所述第二插接部19通过所述第二插头1911插入所述第二插槽1711内，以实现所述天线结构10在垂直于所述第二表面115的方向上的延伸，进而可以通过焊接的方式将所述第二插接部19焊接至所述第二辐射部17上，以实现所 述第二插接部19与所述第二辐射部17之间的稳固连接，提升所述天线结构10各个组成部分之间的稳定性及可靠性。同时，通过在所述天线基板11相对于所述第一辐射部13和第一插接部15的一面设置所述第二辐射部17及第二插接部19，可以有效增加所述天线结构100的低频带宽，并在一定程度上缩减所述天线结构10的体积，从而可以充分利用通信终端内部的空间实现宽频带的天线设计。
请参阅图3，所述第一辐射部13还包括馈入端133及第二辐射体135，所述馈入端133设置于所述基板11相对于所述第一侧边111的一侧，并朝向所述第一辐射体131延伸，用于与信号源连接，从而为所述天线结构10提供激励信号源。所述第二辐射体135与所述馈入端133朝向所述第一辐射体131的一端连接，并与所述第一辐射体131之间形成第一沟槽S1。所述第二辐射体135包括第一连接片1351和第二连接片1353，所述第一连接片1351与所述馈入端133朝向所述第一辐射体131的一端连接，并沿所述第一辐射体131向所述馈入端133的两侧延伸，所述第一连接片1351的一端延伸至超出所述第一辐射体131的端部，所述第二连接片1353与所述第一连接片1351超出所述第一辐射体131的端部的一端连接，并朝向所述第一侧边111延伸。在本实施例中，所述第二辐射体135呈倒“L”型结构，所述第一连接片1351构成所述倒“L”型结构的长边，所述第二连接片1353构成所述倒“L”型结构的短边，所述长边平行于所述第一辐射体131，所述短边垂直于所述第一辐射体131，并延伸至与所述第一辐射体131靠近所述第一侧边111的一侧平齐。
可以理解，通过调节所述第二辐射体135的宽度以及所述第一沟槽S1的宽度可以调节所述第二辐射体135与所述第一辐射体131之间的耦合量，从而可以调节所述天线结构10的谐振频率和带宽。所述第二辐射体135各个组成部分之间可以具有不同的宽度，例如，所述第一连接片1351的宽度可以大于或者小于所述第二连接片1353的宽度。此外，所述第一连接片1351位于所述馈入端133两侧的宽度也可以不同，例如，在本实施例中，所述第一连接片1351位于所述馈入端133远离所述第二连接片1353一侧的宽度大于所述第一连接片1351位于所述馈入端133靠近所述第二连接片1353一侧的宽度。
在一种可选的实施方式中，所述第一辐射部13还包括接地端137及第三辐射体139，所述接地端137设置于所述馈入端133远离所述第二连接片1353的一侧，并朝向所述第一连接片1351延伸，用于与接地面连接，从而为所述天线结构10提供接地回路。所述第三辐射体139一端与所述馈入端133朝向所述第一连接片1351的一端连接，另一端在远离所述第一连接片1351的一侧与所述第一辐射体131连接，所述第三辐射体139与所述第一辐射体131之间形成第二沟槽S2。所述第三辐射体139包括第一连接段1391、第二连接段1393和第三连接段1395，所述第一连接段1391的一端与所述馈入端133朝向所述第一连接片1351的一端连接，另一端朝向远离所述馈入端133的方向延伸至超出所述第一连接片1351的端部，所述第一连接段1391与所述第一连接片1351之间形成第三沟槽S3，所述第二连接段1393的一端与所述第一连接段1391远离所述接地端137的一端连接，另一端朝向所述第一辐射131体延伸，所述第三连接1395段呈倒“L”型，且一端与所述第二连接段1393朝向所述第一辐射体131的一端连接，另一端在远离所述第一连接片1351的一侧与所述第 一辐射体131垂直连接。
可以理解，在本实施例中，所述第二沟槽S2位于所述第三连接段1395与所述第一辐射体131之间，通过调整所述第二沟槽S2的宽度，可以调节所述第三辐射体139与所述第一辐射体131之间的耦合量，从而调节所述天线结构10的谐振频率和带宽。同时，通过调节所述第三沟槽S3的宽度，可以调节所述三辐射体139与所述第二辐射体135之间的耦合量，从而也可以调节所述天线结构10的谐振频率和带宽。
请再次参阅图2，所述第一辐射部13和所述第二辐射部17可以通过PCB印制的方式成型于所述天线基板11上。所述第一插接部15和所述第二插接部19可以为通过切割工艺形成的金属片。在制造所述天线结构10时，可首先根据天线频段的设计需求，设计好第一辐射部13和第二辐射部17的天线形态，并通过切割形成所述第一插接部15和所述第二插接部19；然后将设计好的第一辐射部13和第二辐射部17印制于所述天线基板11上，通过金属过孔连接所述第一辐射部13和第二辐射部17，并在所述第一辐射部13上形成所述第一插槽1311，以及在所述第二辐射部17上形成所述第二插槽1711；进而将所述第一插接部15插入对应的第一插槽1311内，以及将所述第二插接部19插入对应的第二插槽1711内；最后通过焊接的方式固定所述第一插接部15与所述第一辐射部13，并通过焊接的方式固定所述第二插接部19和所述第二辐射部17，从而完成所述天线结构10的制造。
可以理解，所述天线结构10印制于所述天线基板上的部分并不限于图3中示出的耦合天线形式，还可以是但不限于环形(Loop)天线形式、倒F天线(Inverted-F Antenna，IFA)形式等。
请参阅图4，在本发明一个实施例中，还提供一种通信终端100，包括电路板110和设置于所述电路板110一侧的天线结构10，其中，所述天线结构10的具体组成可参考本发明图1-图3所示实施例中的描述，此处不再赘述。可以理解，所述通信终端100可以是但不限于车联网标准终端T-Box、智能手机、平板电脑等通信终端。
为进一步说明本发明实施例提供的天线结构10的优越性，下面通过对不同的天线基板11(即净空区)尺寸条件下以及不同的天线构成条件下的天线辐射性能进行仿真对比分析。如图4所示，L1为净空区的长度，W1为净空区的宽度，L2为电路板110的长度，W2为电路板110的宽度，H1为第一插接部15相对于所述第一表面113的高度，H2为第二插接部19相对于所述第二表面115的高度。在本实施例中，L1＝W2＝68mm，L2＝130mm，W1包括12mm、13mm和15mm三种不同情况；天线构成包括无插接部、单插接部及双插接部三种情况。其中，无插接部是指天线结构只包括如图3所示的第一辐射部13的情况；单插接部是指在第一辐射部13的基础上增加单个插接部的情况，且该插接部仅包括第一插接部15中垂直于第一辐射部13的部分(即插接片151)，而不包括弯折部分(即延伸片153)；双插接部即为如图1中所示的天线结构10。
请参阅图5，图5中所示为实现LTE全频段覆盖时，所述天线10的回波损耗曲线示意图。其中，曲线1为W1＝12mm且天线结构包括双插接部的条件下的回波损耗曲线，曲线2为W1＝13mm且天线结构包括双插接部的条件下的回波损耗曲线，曲线3为W1＝13mm且天线结构包括单插接部的条件下的回波损耗曲线，曲线4为 W1＝15mm且天线结构无插接部的条件下的回波损耗曲线。对比曲线1、2、3、4可以看出：对于W1＝13mm的情况，包括双插接部的天线的带宽要明显比只包括单插接部的天线的带宽更宽；而采用包括双插接部的天线设计，仅需要W1＝12mm的天线净空区大小即可基本实现(除1.5GHz频段)无插接部的天线在W1＝15mm的天线净空区条件下所能达到的带宽覆盖。
请参阅图6，图6中所示为实现LTE全频段覆盖时，所述天线10的效率曲线示意图。其中，曲线a为W1＝13mm且天线结构包括双插接部的条件下的效率曲线，包括a1、a2、a3、a4和a5五段；曲线b为W1＝13mm且天线结构包括单插接部的条件下的效率曲线，包括b1、b2、b3、b4和b5五段；曲线c为W1＝15mm且天线结构无插接部的条件下的效率曲线，包括c1、c2、c3、c4和c5五段。对比效率曲线a、b、c可以看出：W1＝13mm且天线结构包括双插接部时的天线效率要明显优于其他两种条件下的天线效率，且相对于其他两种条件下具有更宽的低频带宽，解决了其他两种条件下天线低频带宽不足的问题。
综上，本发明实施例中所述的天线结构10通过设计所述第一插接部15和所述第二插接部19，可以实现天线辐射体在所述终端的厚度方向的延伸，且通过在所述第一插接部15上设置所述延伸片153，实现天线辐射体在三维空间上的延伸，从而可以在缩减天线体积的情况下，保证足够的低频带宽，进而可以减小所述通信终端的内部设计空间对天线结构的限制以及对天线辐射性能的影响，符合通信终端的超薄化发展需求。
以上所揭露的仅为本发明的优选实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
