如图2所示，微带馈线301和回地线302平行设置，且与天线振子臂303垂直，形成倒F天线的结构。
需要说明的是，上述微带天线采用单极子形式，在其他实施方式中也可采取其他天线形式比如单极子、偶极子、环形天线等天线结构，本发明对此并不限定。

FPC在贴装时更为灵活，可以与壳体的内壁共形。
在一些实施方式中，所述第一频段微带天线为900MHz微带天线；
所述第二频段微带天线为2.4GHz微带天线。
需要说明的是，本发明实施例中的第一频段微带天线和第二频道微带天线还可以工作在其他两个不同的频段。
在一些实施方式中，遥控器的外壳分的材质为聚碳酸酯(Polycarbonate，简称PC)。
需要说明的是，图1-图5中，贴片天线主体的形状、第二馈电同轴线和天线回地端的位置只是一种示例，本发明对此并不限定。
本实施例的遥控器，包括：第一频段微带天线、第二频段微带天线和壳体；
其中，所述第一频段微带天线和第二频段微带天线设置在所述壳体内；所述第二频段微带天线为与所述壳体共形的贴片天线，上述双频天线包括两个频段的微带天线，分别设置在遥控器的壳体内，而且由于第二频段微带天线与壳体共形，因此节省了对遥控器内部空间的占用，能够满足内置的空间尺寸要求，而且由于天线的回地端与内部地连接，使得遥控器内部产生的环境干扰的影响较小，从而实现了遥控器内置的双频天线。
在上述实施例的基础上，进一步，如图3所示，第一频段微带天线1位于壳体的内壁上；
贴片天线主体403位于内壁上，且位于第一频段微带天线1的下方。
在一些实施方式中，本发明实施例的第一频段微带天线1和第二频道微带天线2可以设置在遥控器的壳体内的前方。
具体的，如图3所示，第一频段微带天线1贴合在遥控器的壳体的内壁上，第二频段微带天线2的贴片天线主体403也贴合在遥控器的壳体的内壁上，而且位于第一频段微带天线的下方。
上述具体实施方式中，第二频段微带天线的贴片天线主体位于第一频段微带天线的下方，使得对第一频段微带天线起到了引向的作用，使得第一频段微带天线的方向图得到了改善，由于两个频段的微带天线设置在遥控器的前端的壳体内，使得第一频段微带天线的方向图能集中辐射于遥控器的正前方及其偏下方区域。
在上述实施例的基础上，在一些实施方式中，如图2、图4所示，贴片天线主体403通过天线回地端404以及第二馈电同轴线与第二内部地202连接，且贴片天线主体403与第二内部地202之间间隔一预设距离。
具体的，如图2所示，第二馈电同轴线可以设置在贴片天线主体403的下端边缘处，第二馈电同轴线的接地端与第二内部地202连接。
天线回地端404可以设置在贴片天线主体403的上部，与第二内部地202连接。
在一些实施方式中，天线回地端404可以为柱状，使得贴片天线主体403与第二内部地202之间有一预设距离。第二内部地202，位于贴片天线主体403和遥控器的电池之间，第二内部地202与遥控器的电池连接。
由于遥控器内的空间有限，因此该预设距离较小。示例性的，该预设距离可以为2.75mm。
其中，第一内部地201与壳体的第一部分31对应，第二内部地202与壳体的第二部分32对应。
上述具体实施方式中，贴片天线主体通过天线回地端以及第二馈电同轴线与第二内部地连接，且贴片天线主体与第二内部地之间间隔一预设距离，在遥控器的壳体内部通过共形的方式在离金属体较近的距离的平面内实现了第二频段微带天线。
在一些实施方式中，至少一个第一子微带天线为两个对称设置的所述第一子微带天线；至少一个所述第二子微带天线为两个对称设置的所述第二子微带天线。
具体的，如图1、图2所示，第一子微带天线的数量可以为两个，而且两个第一子微带天线对称设置在所述遥控器的壳体内，使得天线的性能较为稳定。
第二子微带天线的数量可以为两个，而且两个第二子微带天线对称设置在所述遥控器的壳体内，使得天线的性能较为稳定。
在一些实施方式中，微带天线散射参数(Scattering parameters，简称S参数)如图6、图7所示，由图6、图7可知，该天线可工作在900MHz-930MHz(S11<-8dB)及2.4GHz-2.5GHz(S11<-10dB)，带宽分别为30MHz及100MHz，可满足常用的900MHz和2.45GHz频段的覆盖。
天线的方向图如图8、图9所示，图8中线条1为E平面的方向图，线条2为H平面的方向图；图9中线条3为E平面的方向图，线条4为H平面的方向图。由图8、图9可知，天线在900MHz和2.45GHz的最大辐射防线上基本上为正前方及正前方偏下方区域，符合无人机遥控器的使用习惯，满足无人机遥控器的使用需求。
本发明实施例还提供一种无人机，所述无人机包括与其配套使用的遥控器，该遥控器可以使用上述实施例中所述的遥控器，包括：第一频段微带天线、第二频段微带天线和壳体；
