可选的，所述第一辐射体的馈电信号与所述第二辐射体的馈电信号大小相等且相位相反；所述第三辐射体的馈电信号与所述第四辐射体的馈电信号大小相等且相位相反。
为了更好的理解上述馈电方式，请参阅图4进行理解，图4为本发明实施例提供的天线的结构示意图。如图4所示，馈电信号A和馈电信号B分别是双极化的两个极化信号，分别进过3dB功分器分成两支等幅同相信号，其中一支再进过180度反相器将电流相位反相后，180度差分馈入天线的相应端口。经过功分器和反相器处理后的馈电信号A和馈电信号B的各两个反相差分馈电分支分别通过导电件连接天线的低频段V极化馈电辐射体(第一辐射体31和第一辐射体32)和低频段H极化馈电辐射体(第三辐射体33和第四辐射体34)。
第一耦合体41、第二耦合体42与第一辐射体31、第一辐射体32进行耦合，第三耦合体43、第四耦合体44与第三辐射体33、第四辐射体34进行耦合。第一耦合体41和第二耦合体42为高频段V极化，第一辐射体31和第一辐射体32为低频段V极化，第三耦合体43和第四耦合体44为高频段H极化，第三辐射体33和第四辐射体34为低频段H极化。
V极化和H极化是两个相互垂直的极化，其极化方向由图3中坐标定义。低频段V/H极化耦合辐射框体(耦合框体2)、高频段V极化耦合辐射体(第一耦合体41和第二耦合体42)和高频段H极化耦合辐射体(第三耦合体43和第四耦合体44)通过与馈电辐射体之间的电磁耦合产生电磁感应电流，从而产生辐射。本发明的毫米波天线通过该构造具有了双频谐振、双极化的特 性。
上述馈电方式，通过每种极化的多辐射体复合构成，提高了每种极化的方向性和增益。通过使用差分馈电，使天线辐射方向图具有更佳的左右对称性，通过使两个极化的馈电分别馈入相互分离的馈电辐射体，使天线的两个极化间具有更高的端口隔离度和极化纯度。由于本发明的天线单元具有较高的增益，因此较少的阵列天线单元组阵后即可使阵列增益达到3GPP的要求，相比目前的设计可使阵列尺寸减小。
可选的，所述凹槽的开口处设置有台阶结构。
该实施方式中，可以参阅图2进行理解。如图2所示，上述凹槽的开口处设置有台阶结构，该台阶结构可以用以微调天线谐振频率，从而使天线的辐射性能更佳。
可选的，所述板体上设置有至少两个天线单元，所述至少两个天线单元沿所述板体的长度方向排布。
该实施方式中，可以参阅图5进行理解，图5为本发明实施例提供的天线的结构示意图。如图5所示，上述天线上设置有至少两个天线单元，该至少两个天线单元沿天线的长度方向排布，从而便于形成天线阵列，该天线阵列可以是毫米波天线阵列，天线阵列化后可以通过同时馈电并调整子天线单元馈电的相位差对天线阵列进行波束赋形和波束扫描，提高了天线辐射方向性和增益，并提高了辐射的空间覆盖率。
当然，还可以在天线单元大体构造不变的情况下对天线单元内的各辐射体位置进行调整和优化，或者还可以对组成阵列的天线单元的朝向进行统一的90度转向调整等等。
可选的，所述至少两个天线单元的凹槽开口朝向相同。
该实施方式中，亦可以参阅图5进行理解。如图5所示，上述至少两个天线单元的凹槽开口朝向相同。
可选的，所述至少一个天线单元为毫米波天线单元。
该实施方式中，上述至少一个天线单元为毫米波天线单元。
可选的，所述第一辐射体、所述第二辐射体、所述第一耦合体和所述第二耦合体远离所述凹槽槽底的一面，均与所述板体外侧壁所在的平面平齐。
该实施方式中，可以参阅图1进行理解。如图1所示，上述第一辐射体、上述第二辐射体、上述第一耦合体和上述第二耦合体远离上述凹槽槽底的一面，均与上述板体外侧壁所在的平面平齐。通过这种设置方式，可以保证电子设备具有较优的外观。
可选的，所述耦合框体围闭的空间为矩形空间。
该实施方式中，上述耦合框体围闭的空间为矩形空间。
可选的，所述四个辐射体均为T型结构。
该实施方式中，上述四个辐射体均为T型结构。

本发明实施例还提供一种电子设备，包括上述天线，所述电子设备还包括金属边框，所述天线的板体为所述金属边框的一部分。
可选的，所述天线还包括第一天线，所述天线的至少一个天线单元所在的辐射体亦为所述第一天线的辐射体，所述辐射体为所述板体的至少一部分，所述第一天线为非毫米波天线。

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。
