其中，电子设备上还可以设置有其他通信天线，而金属边框10的第一部分可以作为其他通信天线的辐射体，需要说明的是，容置槽11也可以开设于金属边框10的第一部分上，这样，本发明实施例中馈电针30和第一绝缘介质体20构成的介质谐振天线即可以与其他通信天线共用金属边框10的第一 部分。
当然，容置槽11也可以开设于金属边框10的第二部分，第二部分与第一部分为不同的部分。这样，本实施例的介质谐振天线可以与其他通信天线分开设置。
需要说明的是，上述其他通信天线可以为蜂窝(cellular)天线或者非蜂窝(no-cellular)天线。而金属边框10可以为一个封闭的矩形框，当然，也可以为不封闭的矩形框，例如：金属边框10包括四条侧边框，但是相邻的两条侧边框之间可以通过绝缘介质进行填充，既可以达到将相邻的两条侧边框绝缘设置的目的，也可以达到连接相邻两条侧边框的目的。
当然，也可以只在四条侧边框中某两条相邻的侧边框之间填充绝缘介质，其他侧边框之间不填充绝缘介质。具体设置方式在此不做限定。
另外，参见图2，电子设备还可以包括接地的地板40，地板40可以与金属边框10的各个侧边框连接，或者只与金属边框10的部分侧边框连接，这样，金属边框10通过地板40可以实现接地的目的。当然，上述地板40也可以被称作为主上、框体，可以用于固定印制电路板等部件。
可选地，参见图3，所述馈电通孔12的数量为N个，且所述馈电通孔12与所述馈电针30的数量一一对应，所述N为大于1的整数。
其中，由于N为大于1的整数，则馈电通孔12的数量为至少两个，且每一个馈电通孔12内均穿设有馈电针30，即可以理解为馈电通孔12与馈电针30的数量为一一对应的，则容置槽11内设置有至少两根馈电针30，这样，可以构成多极化，增强天线的辐射性能。
需要说明的是，作为一种可选的实施方式，至少两根馈电针30可以与同一个信号源电连接；作为另一种可选的实施方式，每一根馈电针30均可以对应连接一个信号源，即当馈电针30的数量为N个，则信号源的数量也为N个，且馈电针30和信号源为一一对应。
当N为2时，两个馈电通孔12内的馈电针30可以构成极化，即两个馈电通孔12内的两根馈电针30可以为一组，且每组内的两根馈电针30构成极化，增加天线的无线连接能力，减少通信断线的机率，增加通信效果和用户体验。例如：当一组内的两根馈电针30构成一对差分馈电端口时，则该组内 的两根馈电针30极化。
需要说明的是，一根馈电针30也可以单独构成极化，则此时两根馈电针30可以构成两个极化，上述两个极化也可以被称作为双极化。这样，同样可以增加天线的无线连接能力，减少通信断线的机率，增加通信效果和用户体验。
本发明实施例中，馈电通孔12的数量为至少两个，且馈电针30的数量与馈电通孔12的数量为一一对应，从而增强了天线的辐射性能。
可选地，所述馈电针30构成至少一对差分馈电端口。
需要说明的是，上述N个馈电针30可以构成至少一对差分馈电端口，而构成一对差分馈电端口的两个馈电针30上的输入信号的幅度相等，且相位相差180度。
需要说明的是，差分馈电端口的数量在此不做限定，例如：馈电针30的数量为4个，则4个馈电针30中有2个馈电针30可以构成1对差分馈电端口，而另外的2个馈电针30则不构成差分馈电端口；当然，上述4个馈电针30也可以分别构成2对差分馈电端口。
另外，依次连接上述4个馈电针30的位置可以得到一个矩形，而上述4个馈电针30可以分别位于矩形的1个直角所在的位置，而构成1对差分馈电端口的2个馈电针30可以分别位于矩形的对角线所连接的2个直角位置。
作为一种可选的实施方式，N个所述馈电通孔12中每两个所述馈电通孔12组成一个通孔组，每个所述通孔组包括的两个馈电通孔12内设置的馈电针30构成差分馈电端口。
其中，每个通孔组包括的两个馈电通孔12内设置的馈电针30构成差分馈电端口，即上述通孔组包括两个馈电通孔12，且每个馈电通孔12内均穿设有一根馈电针30，可以理解为：每个通孔组内包括两根馈电针30，而上述两根馈电针30构成差分馈电端口，即上述两根馈电针30的输入信号的幅度相等，且相位相差180度。
而上述两根馈电针30可以均连接至同一个信号源上，从而可以更好的保证上述馈电针30的输入信号的幅度相等。另外，该信号源可以为毫米波信号源。
需要说明的是，馈电通孔可以包括两个通孔组，且一个通孔组中的两个馈电通孔12可以位于同一水平方向上，且该通孔组中的两个馈电通孔12之间的连线可以为第一连线(例如：图3中B连线)；而另一个通孔组中的两个馈电通孔12可以位于同一竖直方向上，且该通孔组中的两个馈电通孔12之间的连线可以为第二连线(例如：图3中C连线)。第一连线和第二连线相交。可选地，第一连线和第二连线的相交位置可以位于容置槽11的槽底的中间位置。这样，通过上述两个通孔组内的设置的馈电针30可以形成多进多出(Multiple Input Multiple Output，MIMO)功能，同时，还可以构成双极化，增加了天线的无线连接能力，减少了通信断线的机率，提升了通信效果和用户体验。
本发明实施例中，由于每个通孔组中包括的两根馈电针30构成差分馈电端口，这样，可以解决介质谐振天线方向图随着频率变化这一问题，保证天线的最大辐射方向一致，同时提高双极化的极化隔离度，进而增强了天线的辐射性能。
可选地，N个所述馈电通孔12均开设于所述容置槽11的槽底。
本发明实施例中，由于馈电通孔12均开设于容置槽11的槽底，降低了加工难度，同时还可以使得N个馈电针30均可以集中分布于容置槽11的槽底，从而使得天线的最大辐射方向可以朝向背离容置槽11的槽底的一侧方向，进而进一步加强天线的辐射性能。
可选地，参见图1、3、4和5，所述第一绝缘介质体20与所述容置槽11的侧壁之间还设置有第二绝缘介质体50，且所述第二绝缘介质体50环绕所述第一绝缘介质体20设置。
其中，图4可以被认为是图3中所示电子设备各部件的装配后对应的截面示意图，而图5可以被认为是图2中A区域的另一种结构放大图。
其中，第二绝缘介质体50的介电常数可以小于第一绝缘介质体20的介电常数。可以选择介电常数较高的材料制造第一绝缘介质体20(例如：通常可以选择介电常数大于10的材料)，而选择介电常数较低的材料制造第二绝缘介质体50(例如：通常可以选择介电常数小于10的材料)。这样，可以使得天线激励起介质谐振模式以及容置槽11的谐振模式，从而更好的增加天线 的带宽。
当信号源为毫米波信号源时，参见图6，图6为此时介质谐振天线的反射系数图，从图6中可知：天线的带宽可以达到25.9GHz-41.6GHz，基本覆盖第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)已经定义的n257，n258，n260，n261频段，即可以覆盖全球主流第五代移动通信技术(5th generation mobile networks，5G)毫米波频段，从而提升了用户的移动漫游体验。另外，还可以参见图7和图8，图7为介质谐振天线在28GHz时的方向图，而图8为介质谐振天线在39GHz时的方向图。
本发明实施例中，第一绝缘介质体20与容置槽11的侧壁之间还设置有第二绝缘介质体50，这样，可以增强对第一绝缘介质体20的固定效果。
可选地，所述第一绝缘介质体20的介电常数大于所述第二绝缘介质体50的介电常数。这样，即第一绝缘介质体20的介电常数可以较高，从而可以激励起介质谐振模式以及容置槽11的谐振模式，从而扩展了介质谐振天线的带宽，提升通信效果。
作为一种可选的实施方式，所述第二绝缘介质体50分别与所述容置槽11的侧壁和所述第一绝缘介质体20抵接。
本发明实施例中，第二绝缘介质体50分别与容置槽11的侧壁和第一绝缘介质体20抵接，这样，可以增强对第一绝缘介质体20的固定效果，避免第一绝缘介质体20朝向容置槽11的侧壁倾斜的现象的发生。
可选地，参见图1、3和4，所述第一绝缘介质体20上背离所述容置槽11的槽底的表面上层叠设置有第三绝缘介质体60。
其中，作为一种可选的实施方式，第三绝缘介质体60用于封闭容置槽11，即第三绝缘介质体60的边缘可以分别与容置槽11的侧壁抵接，而第三绝缘介质体60可以位于容置槽11的开口处，这样，第三绝缘介质体60可以与金属边框10的表面位于同一水平面上，即保证了金属边框10的完整度。
其中，第三绝缘介质体60可以分别与第一绝缘介质体20和第二绝缘介质体50抵接，这样，可以使得对第三绝缘介质体60的支撑效果较好。
本发明实施例中，通过设置第三绝缘介质体60，从而可以对第一绝缘介质体20和第二绝缘介质体50形成保护。另外，当第三绝缘介质体60用于封 闭容置槽11时，第三绝缘介质体60同时也可以保证金属边框10的表面的完整性，另外还可以起到防水防尘效果。
需要说明的是，第三绝缘介质体60内部可以设置有中空区域，而第一绝缘介质体20背离容置槽11的槽底的表面上可以形成凸起，且该凸起可以容置于上述中空区域内。这样，可以增强第三绝缘介质体60和第一绝缘介质体20之间的连接效果。
可选地，所述第一绝缘介质体20的介电常数大于所述第三绝缘介质体60的介电常数。
本发明实施例中，由于第一绝缘介质体20的介电常数大于第三绝缘介质体60的介电常数，这样，同样可以扩展天线的带宽，从而提升通信效果。
可选地，所述第一绝缘介质体20与所述容置槽11的侧壁之间还设置有第二绝缘介质体50，且所述第二绝缘介质体50环绕所述第一绝缘介质体20设置，所述第三绝缘介质体60的介电常数大于或等于所述第二绝缘介质体50的介电常数。
其中，可以理解的是，本实施例中的第二绝缘介质体50与上述实施例中的第二绝缘介质体50可以为同一个绝缘介质体。
需要说明的是，作为一种可选的实施方式，第二绝缘介质体50的介电常数可以为2.5，损耗角正切可以为0.005；第三绝缘介质体60的介电常数可以为3，损耗角正切可以为0.01；第一绝缘介质体20的介电常数可以为21，损耗角正切可以为0.005。
本发明实施例中，由于第三绝缘介质体60的介电常数大于或等于第二绝缘介质体50的介电常数，这样，在保证第三绝缘介质体60的介电常数较低的情况下，可以保证第三绝缘介质体50的连接强度较好，从而避免第三绝缘介质体60的连接强度较差导致第三绝缘介质体60易被损坏的现象的发生。
可选地，参见图5，所述金属边框10上开设有M个所述容置槽11，每一个所述容置槽11内均设置有所述第一绝缘介质体20和所述馈电针30，M个所述容置槽11阵列分布，所述M为大于1的整数。
本发明实施例中，由于金属边框10开设有M个所述容置槽11，且每一个容置槽11内均设置有第一绝缘介质体20和馈电针30，这样，增加了天线 的数量，从而可以进一步增强电子设备的辐射性能。同时，M个容置槽11阵列分布，可以使得容置槽11的分布更加整洁。
需要说明的是，本发明实施例中给出的各个实施例可以应用于具有无线城际网路(WMAN)、无线广域网路(WWAN)、无线区域网路(WLAN)、无线个人网路(WPAN)、多输入多输出(MIMO)、射频识别(RFID)，甚至是近场通信(NFC)、无线充电(WPC)，或FM等功能的电子设备上；当然，还可以应用于可佩戴的电子器件(如助听器或心率调整器等)上。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本发明的保护之内。
