具体实施例
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1示出了根据本申请一个实施例的双频双极子天线的结构示意图。图2示出了该实施例的双频双极子天线的正视图。图3示出了该实施例的双频双极化天线的分解视图。
如图1、图2和图3所示，该双频双极子天线包括水平极化单元1、垂直极化单元2、分隔板3、地板4、第一同轴馈线5和第二同轴馈线6。
在本实施例中，水平极化单元1包括水平布置的第一基板。第一基板中可以设置有第一辐射体11。第一辐射体11可以接收双频段的水平极化波。水平极化波为电场方向与地面平行的无线电波。
实践中，基板是制造PCB(Printed circuit board，印制电路板)的基本材料。基板可以是覆铜箔层压板。本申请实施例对第一基板的形状不 作限定，例如，可设置为矩形基板，也可以设置为圆形基板等。
在本实施例中，垂直极化单元2包括两个呈十字型垂直布置的第二基板，各第二基板中设置有第二辐射体21。第二辐射体21也可以接收双频段的垂直极化波。垂直极化波为电场方向垂直于地面的无线电波。
需要说明的是，双频段既可以为WiFi双频，也可以为GSM(Global System for Mobile Communications，全球移动通信***)双频或者CDMA(Code Division Multiple Access，码分多址)双频，从而满足无线通信设备的使用需求。以双频段为WiFi双频为例，两个频段可以分别为2.4GHz频段和5GHz频段。本实施例对频段的具体数值不作限定。
在本实施例中，分隔板3布置于水平极化单元1与垂直极化单元2之间。分隔板3的底面设置有金属片，金属片与各第二辐射体相连接。通过分隔板3隔离水平极化单元1与垂直极化单元2，有助于在保证天线辐射性能的情况下，减小天线尺寸。
实践中，分隔板也可以采用基板，金属片可布置于基板的底面。本申请实施例对该基板的形状不作限定，例如，可设置为矩形基板，也可以设置为圆形基板等。
在本实施例中，第一同轴馈线5与地板4和水平极化单元1相连接。第二同轴馈线6与地板4和垂直极化单元2相连接。其中，同轴馈线是馈线的一种。馈线即连接天线与发射机或接收机的导线，又称电缆线，起传输信号的作用。它的主要任务是有效地传输信号能量，将发射机发出的信号功率以最小的损耗传送到天线的输入端，或将天线接收到的信号以最小的损耗传送到接收机输入端，同时本身不应产生杂散干扰信号。同轴馈线的两根导线为芯线和屏蔽铜网。因铜网接地，两根导线对地不对称，因此也叫做不对称式或不平衡式传输线。同轴馈线工作频率范围宽、损耗小，对静电耦合有一定的屏蔽作用。
由于天线的承载设备的结构尺寸趋向小型化，对天线的小型化要求比较高。但是天线特性受限于物理尺寸，往往小型化会带来辐射特性的损失。而本申请实施例所提供的双频双极子天线，通过在水平极化单元中设置用于接收双频段的水平极化波的第一辐射体，在垂直极化单元中设置用于接收双频段的垂直极化波的第二辐射体，并在水平极化单元与 垂直极化单元之间设置分隔板，从而在保证了辐射性能的同时降低了天线尺寸，满足了小型化智能设备的设计需求。
在本实施例的一些可选的实现方式中，第一基板可以具有相对设置的第一面和第二面。第一基板的第一面和第二面中分别设置有第一辐射体11。图4示出了第一基板的放大图。如图4所示，第一面中的第一辐射体11与第二面中的第一辐射体11可以反向布置，从而能够多个角度接收无线电波，有助于提升天线的全向性能。
在本实施例的一些可选的实现方式中，如图4所示，每一个第一辐射体11可以由多个F型部件连接而成。每个F型部件包括高频段枝节111、低频段枝节112和连接件113。在每个F型部件中，连接件113分别与高频段枝节111和低频段枝节112电连接，且高频段枝节111和低频段枝节112位于上述连接件的同一侧。F型部件中的低频段枝节112可以长于高频段枝节111。
需要说明的是，此外，每一个第一辐射体不限于由四个F型部件连接而成，还可以由其他数量的F型部件连接而成。
在本实施例的一些可选的实现方式中，每个F型部件中的连接件113可以呈渐变形式，由一端至另一端逐渐变窄。从而可以起到调节阻抗的作用。其中，连接件113较窄一端可以与低频段枝节112的一端电连接。连接件113较宽一端可以位于第一辐射体的中心，且第一辐射体中各F型部件中的连接件的较宽一端可以相互电连接。
需要说明的是，第一辐射体11不限于采用多个F型部件构成，还可以采用其他能够接收双频段的水平极化波的部件构成。
在本实施例的一些可选的实现方式中，垂直极化单元中的每一个第二基板可以具有相对设置的第一面和第二面。第二基板的第一面和第二面中分别设置有第二辐射体21。上述第二基板的第一面中的第二辐射体与上述第二基板的第二面中的第二辐射体也可以反向布置。
在本实施例的一些可选的实现方式中，请参见图5所示的第二辐射体的放大图，每一个第二辐射体21可以包括倒锥形部件211、L型高频段枝节212和L型低频段枝节213。L型高频段枝节212与倒锥形部件211的一端电连接，L型低频段枝节213与倒锥形部件211的另一端电连 接。
在本实施例的一些可选的实现方式中，如图2所示，分隔板3中可以开设有通孔。第一同轴馈线5可以穿过上述通孔，与地板4和水平极化单元1相连接。
在本实施例的一些可选的实现方式中，第一同轴馈线5包括内层芯线和外层。第一同轴馈线5的外层可以与地板4电连接；第一同轴馈线5的内层芯线可以与第一辐射体11电连接。
在本实施例的一些可选的实现方式中，第二同轴馈线6包括内层芯线和外层。上述第二同轴馈线6的外层可以与地板4电连接。第二同轴馈线6的内层芯线可以与第二辐射体21电连接。
在本实施例的一些可选的实现方式中，上述双频双极化天线高度为低频段波长的0.16倍，上述双频双极化天线宽度(不合地板)为上述低频段波长的0.25倍。由此，可在保证了辐射性能的同时降低了天线尺寸，满足了小型化智能设备的设计需求。
由于天线的承载设备的结构尺寸趋向小型化，对天线的小型化要求比较高。但是天线特性受限于物理尺寸，往往小型化会带来辐射特性的损失。而本申请实施例所提供的双频双极子天线，通过在水平极化单元中设置用于接收双频段的水平极化波的第一辐射体，在垂直极化单元中设置用于接收双频段的垂直极化波的第二辐射体，并在水平极化单元与垂直极化单元之间设置分隔板，从而在保证了辐射性能的同时降低了天线尺寸，满足了小型化智能设备的设计需求。
