现有的平板及手机等终端设备中常配备有Wi-Fi天线和蓝牙天线，而Wi-Fi天线和蓝牙天线通常是工作在同一频段，且Wi-Fi模块和蓝牙模块共天线时，为时分策略，如此会导致蓝牙模块工作时，Wi-Fi模块的性能急剧下降。
由此，本申请实施例提供了一种Wi-Fi及蓝牙组合天线装置及其配置方法、终端设备，能够提高Wi-Fi天线和蓝牙天线的隔离度，从而使得蓝牙天线和Wi-Fi天线在同一频段同时工作时，均具有较佳地工作性能。
在本实施例中，终端设备可以是平板电脑、笔记本电脑或手机等。
第一方面，请参考图1～图3，本申请实施例提供了一种Wi-Fi及蓝牙组合天线装置，其包括Wi-Fi天线10、接地板20、微扰单元30及蓝牙天线40。其中，Wi-Fi天线10设置于接地板20的边缘处，并能够在接地板20上产生接地板20电流。微扰单元30则设置于接地板20的边缘处，且用于在受到接地板20电流激励后，产生和接 地板20电流的来波方向相逆向的反向电流，反向电流和接地板20电流叠加后在接地板20上形成电流零点区。蓝牙天线40设置于接地板20的边缘对应于电流零点区(如图6中虚线框中所示)的位置。
示例性地，Wi-Fi天线10可以是左手天线，Wi-Fi天线10的辐射主体的长度可以是15mm，其厚度可以是1mm，而天线净空可以是1mm。
示例性地，接地板20的长宽尺寸可以是245mm/155mm，也可以是155mm/80mm或245mm/200mm等。
以下对本申请实施例提供的Wi-Fi及蓝牙组合天线装置作进一步说明：本申请实施例提供的Wi-Fi及蓝牙组合天线装置，由于Wi-Fi及蓝牙组合天线装置包括有微扰单元30，而微扰单元30能够Wi-Fi天线10在接地板20上形成地板电流时，受到该地板电流的激励而产生逆向于该地板电流的来波方向的反向电流，这样反向电流和地板电流相互叠加，便能够在地板上形成电流零点区，那么蓝牙天线40设置于接地板20的边缘对应于电流零点区的位置，便较佳地降低了地板电流对蓝牙天线40的影响，较佳地提高了蓝牙天线40和Wi-Fi天线10之间的隔离度，也较佳地实现了蓝牙天线40和Wi-Fi天线10在同一故障频段同时工作时的解耦，使得蓝牙天线40和Wi-Fi天线10在同一频段同时工作时，均具有较佳地工作性能，也使得Wi-Fi及蓝牙组合天线装适用于具有金属背盖的终端设备。
示例性地，如图7和图8所示，对比Wi-Fi及蓝牙组合天线装置中未加入微扰单元30和加入微扰单元30前后(图7中标号1的曲线表示未加入微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图7中标号2的曲线表示加入微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图)，Wi-Fi天线10的S11曲线无明显凹坑，Wi-Fi天线10的辐射效率无明显恶化，Wi-Fi天线10的传输曲线S12出现隔离度零点(S12凹坑)，隔离度超过40dB，得到明显改善(隔离度的峰值改善8～12dB，均值改善6dB左右)。
在本申请的另一些实施例中，如图1～图3所示，Wi-Fi天线10和微扰单元30分别设置于接地板20的相对的两处角部位置。具体地，通过将Wi-Fi天线10和微扰单元30分别设置于接地板20的相对的两处角部位置，这样能够减小微扰单元30对于Wi-Fi天线10的影响，从而使得Wi-Fi天线10在微扰单元30的存在下也能够具有较佳地带宽性能、传输效率、传输方向性和双手模性能等工作性能。
示例性地，Wi-Fi天线10和微扰单元30可分别设置于地板的同侧边缘的两端位置，也可以是Wi-Fi天线10和微扰单元30分别设置于地板的相邻两侧边缘。比如Wi-Fi天线10可以放置在接地板20的长边处，而微扰单元30可以放置在接地板20的短边处。
在本申请的另一些实施例中，如图3和图4所示，微扰单元30的数量为两个，两个微扰单元30相对于接地板20的中心呈对角设置于接地板20的两处角部位置，Wi-Fi天线10设置于接地板20的另一处角部位置。
具体地，通过将微扰单元30的数量设定为两个，这样两个微扰单元30所产生的反向电流通过和Wi-Fi天线10所产生的地板电流相叠加，则能够更佳地抵消Wi-Fi天线10所产生的地板电流，使得蓝牙天线40所受到的来自地板电流的影响更小，从而 使得蓝牙天线40和Wi-Fi天线10之间具有更佳地隔离度。
示例性地，两个微扰单元30可以分别放置在接地板20的相对两侧长边，也可以分别放置在接地板20的相邻的长边和短边处，也即两个微扰单元30可以是呈平行或正交放置。
在本申请的另一些实施例中，两个微扰单元30的谐振频率可以是相同的，也可以是不同的。而当两个微扰单元30不同时，两个微扰单元30的谐振频率的谐振频率的差值大于0MHz，且小于或等于100MHz。这样可以更佳地抵消Wi-Fi天线10所产生的地板电流，从而使得蓝牙天线40和Wi-Fi天线10之间具有更佳地隔离度。
示例性地，如图8所示，当两个微扰单元30平行设置，且谐振频率相同时，隔离度峰值提高了10dB(图8中标号1的曲线表示未加入微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图8中标号3的曲线表示加入两个谐振频率相同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图8中标号2的曲线表示加入两个谐振频率不同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图)，而当两个微扰单元30平行设置，且谐振频率不同时，隔离度峰值则提高了23dB，均值提升了7dB。
示例性地，如图8所示，当两个微扰单元30平行设置，且谐振频率相同时，隔离度峰值提高了10dB(图8中标号1的曲线表示未加入微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图8中标号3的曲线表示加入两个谐振频率相同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图8中标号2的曲线表示加入两个谐振频率不同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图)，而当两个微扰单元30平行设置，且谐振频率不同时，隔离度峰值则提高了23dB，均值提升了7dB。
示例性地，如图9所示，当两个微扰单元30正交设置，且谐振频率相同时，隔离度峰值提高了8dB～12dB(图9中标号1的曲线表示未加入微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图9中标号3的曲线表示加入两个谐振频率相同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图，图9中标号2的曲线表示加入两个谐振频率不同的微扰单元30时的Wi-Fi及蓝牙组合天线装置的S参数随频率变化的曲线图)，而当两个微扰单元30正交设置，且谐振频率不同时，隔离度峰值则提高了19dB～24dB，均值提升了5dB～7dB。
示例性地，如图10所示，当两个微扰单元30正交设置，且谐振频率不同时，隔离度峰值则提高了36dB，均值提升了10dB。而Wi-Fi天线10的方向性仅由3.7dBi变为3.8dBi，因此可知两个微扰单元30的存在对Wi-Fi天线10的影响基本可以忽略不计。
示例性地，如图11和图12所示，当接地板20的长宽尺寸245mm/200mm时，结果表明隔离度峰值可以提升10dB(图11所示)。当接地板20的长宽尺寸为155mm/80mm时，结果表明独立蓝牙放在Wi-Fi和微扰单元形成的零点区位置，隔离度峰值可以提升3.5dB(图12所示)。
在本申请的另一些实施例中，如图5所示，微扰单元30包括辐射体31、连接部33和阻容匹配网络32，辐射体31通过连接部33和接地板20相连接，阻容匹配网络 32连接于辐射体31的开放端，并用于向接地板20输出反向电流。
具体地，辐射体31的开放端朝向地板方向，这样能够使得阻容匹配网络32更佳地向接地板20输出反向电流。更具体地，阻容匹配网络32为包括电阻和电容或者还包括开关的集总元件。
示例性地，当两个微扰单元30的谐振频率相同时，阻容匹配网络32具有相同的等效电容(比如均为0.3pF)。而当两个微扰单元30的谐振频率相同时，阻容匹配网络32具有不同的等效电容(比如分别为0.3pF和0.35pF)。
示例性地，如图13～图14所示，还可标记Wi-Fi天线10不同工作频段时，地板电流在接地板20边缘处的零点分布位置，并汇总分析，以得出微扰单元30在接地板20边缘处放置的理想位置。
在本申请的另一些实施例中，连接部33和辐射体31一体成型。具体地，通过使得连接部33和辐射体31一体成型，这样可以提高微扰单元30的整体结构强度，使得连接部33和辐射体31之间的连接处不易发生裂纹，如此也提高了微扰单元30的工作可靠性。
示例性地，连接部33和辐射体31可以采用一体铸造成型等成型方式制得。
在本申请的另一些实施例中，连接部33为金属弹片，金属弹片的一端和辐射体31焊接连接，金属弹性的另一端和接地板20焊接连接。具体地，通过将连接部33设计为金属弹片，这样连接部33也具有了较佳地弹性缓冲性能，那么在微扰单元30受到外界的冲击振动的影响下时，连接部33也能够通过弹性变形来化解微扰单元30所受到的冲击力，使得微扰单元30不易自接地板20上脱开。
在本申请的另一些实施例中，辐射体31的长度、厚度和净空满足下列关系：
10mm≤L≤18mm；
0.8mm≤C≤1.2mm；
0.8mm≤D≤1.2mm；
其中，L表示辐射体31的长度，C表示辐射体31的厚度，D表示辐射体31的净空。
具体地，通过将辐射体31的长度、厚度和净空设定在上述限值范围内，这样一方面能够使得辐射体31在受到地板电流的激励时，能够顺利地产生反向电流，另一方面，当微扰单元30和手写笔50均位于接地板20的同一侧时，也能够避免挤占手写笔50的放置空间。
如图15所示，第二方面，本申请实施例还提供了一种Wi-Fi及蓝牙组合天线装置的配置方法，包括以下步骤：
提供Wi-Fi天线10和接地板20，将Wi-Fi天线10设置于接地板20的边缘处；
提供微扰单元30，将微扰单元30设置于接地板20的边缘，并使得微扰单元30和Wi-Fi天线10相对设置；
获取Wi-Fi天线10产生于接地板20上的接地板20电流和微扰单元30产生于接地板20上的反向电流相叠加后形成于接地板20上的电流零点区的位置；
提供蓝牙天线40，将蓝牙天线40设置于接地板20的边缘对应于电流零点区的位置。
具体地，Wi-Fi及蓝牙组合天线装置的配置方法的步骤顺序可以是：
S1：提供Wi-Fi天线10和接地板20，将Wi-Fi天线10设置于接地板20的边缘处；
S2：提供微扰单元30，将微扰单元30设置于接地板20的边缘，并使得微扰单元30和Wi-Fi天线10相对设置；
S3：获取Wi-Fi天线10产生于接地板20上的接地板20电流和微扰单元30产生于接地板20上的反向电流相叠加后形成于接地板20上的电流零点区的位置；
S4：提供蓝牙天线40，将蓝牙天线40设置于接地板20的边缘对应于电流零点区的位置。
本申请实施例提供的Wi-Fi及蓝牙组合天线装置的配置方法，通过将微扰单元30设置于接地板20的边缘，并使得微扰单元30和Wi-Fi天线10相对设置，这样微扰单元30便能够Wi-Fi天线10在接地板20上形成地板电流时，受到该地板电流的激励而产生逆向于该地板电流的来波方向的反向电流，这样反向电流和地板电流相互叠加，便能够在地板上形成电流零点区，那么蓝牙天线40设置于接地板20的边缘对应于电流零点区的位置，便较佳地降低了地板电流对蓝牙天线40的影响，较佳地提高了蓝牙天线40和Wi-Fi天线10之间的隔离度，也较佳地实现了蓝牙天线40和Wi-Fi天线10在同一故障频段同时工作时的解耦，使得蓝牙天线40和Wi-Fi天线10在同一频段同时工作时，均具有较佳地工作性能。
第三方面，本申请实施例提供了一种终端设备，包括上述的Wi-Fi及蓝牙组合天线装置。其中终端设备可以是平板电脑、笔记本电流或手机等。
本申请实施例提供的终端设备，由于包括有上述的Wi-Fi及蓝牙组合天线装置，而上述的Wi-Fi及蓝牙组合天线装置通过其内设有的微扰单元30实现了蓝牙天线40和Wi-Fi天线10在同一故障频段同时工作时的解耦，使得蓝牙天线40和Wi-Fi天线10具有较佳地隔离度，能够在同一频段同时工作时，均具有较佳地工作性能，这样终端设备在连接Wi-Fi网络，并同时使用蓝牙天线40连接外部设备，比如手写笔50时，也能够满足蓝牙天线40和Wi-Fi天线10互不影响，从而使得终端设备具有了较佳地用户产品体验。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
