具体实施方式
如图1所示，图1为相关技术中双接收天线测角的结构示意图。双接收天线实现测角的具体原理为：不同方向的电磁波信号到达两个接收天线的路径不同，引入了额外的路径差，从而引入额外的时间差，额外的时间差对应额外的相位差，通过两个接收天线接收电磁波信号的相位差与到达角的关系实现测角。在图1中，两个接收天线之间的间距为d。发射天线和接收天线的电场表达式如下：



天线的信号到达相位差(Phase-Difference-of-Arrival，PDOA)为发射天线与接收天线电场的点积的相位差，表达式如下：





r1-r2＝d sinθ
其中，Rn用于表示发射天线与接收天线的交叉极化比的乘积；ε用于表示介电常数；α2-α1用于表示两个接收天线的馈电相差；用于表示两个接收天线相位方向图的一致性；用于表示发射天线相位方向图。
从上述表达式中可以较直观的看到影响PDOA的因素有：发射和接收天线的极化比、接收天线相位中心间距、接收天线相位方向图、发射天线相位方向图、天线所处的介质环境、接收天线馈电相差。特别地，除了空间相位差，极化的不一致性也会引入额外的相位差。
通过理论推导分析，当Rn→∞或Rn→0，即收发天线极化匹配，且具有高极化比时，PDOA主要受接收天线相位方向图的一致性的影响(稳定的相位中心)。接收天线越一致，PDOA曲线收敛度越好。而当极化失配，即R1→∞，R2→0或者R2→∞，R1→0，会出现∞·0，此时PDOA不确定。一般地，收发极化匹配时，若极化纯度一般，PDOA不仅受接收天线的主极化影响，也会受到接收天线的交叉极化和发射天线影响。为此，本申请提供一种交叉极化较小，测角精度较高的天线组件及电子设备。

本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
如图2所示，图2为本申请实施例提供的一种电子设备100的结构示意图。电子设备100可以是手机、平板电脑、笔记本电脑、计算机、手表、无人机、机器人、基站、雷达、客户前置设备(Customer Premise Equipment，CPE)、车载设备、家电设备等具有无线通信功能的设备。本申请实施例以手机为例。

天线组件1用于实现电子设备100的无线通信功能。本申请提供的天线组件1为UWB天线组件，即一种用于短距离无线通信的天线组件。天线组件1的传输距离可以在10m以内，使用1GHz以上带宽。由于UWB不采用载波，而是利用纳秒至微秒级的非正弦窄脉冲传输数据，因此，UWB天线组件所占的频谱范围很宽，适用于高速、近距离的无线个人通信。FCC规定，UWB的工作频段范围从3.1GHz到10.6GHz，最小工作频宽为500MHz。目前主流的UWB频段中心频率为6.5GHz和8GHz。可以理解的，本申请提供的天线组件1的工作频段范围可以位于3.1GHz到10.6GHz之间，最小工作频宽可以为500MHz，天线组件1的中心频率可以包括6.5GHz或8GHz。以下实施例中，以天线组件1的中心频率包括8GHz为例。
请参照图4和图5，图4为本申请实施例提供的一种天线组件1的结构示意图，图5为图4所示天线组件1中第一天线辐射体11的结构示意图。天线组件1包括沿第一目标方向间隔排布的第一天线辐射体11和第二天线辐射体12。天线组件1还可以包括介质层10。第一天线辐射体11和第二天线辐射体12可以设于介质层10的表面。

第一自由端1103分别与第二枝节112、第三枝节113相连，第二枝节112与第一枝节110之间形成第一间隙部L1，第三枝节113与第一枝节110之间形成第二间隙部L2。
具体的，第二枝节112靠近第一自由端1103的一端与第一自由端1103相连，第二枝节112远离第一自由端1103的一端与第一枝节110间隔设置，从而使得第二枝节112与第一枝节110之间形成第一间隙部。第三枝节113靠近第一自由端1103的一端与第一自由端1103相连，第三枝节113远离第一自由端1103的一端与第一枝节110间隔设置，从而使得第三枝节113与第一枝节110之间形成第二间隙部。其中，第二枝节112远离第一自由端1103的一端可以靠近第一枝节110的第一接地端1101，或者，第二枝节112远离第一自由端1103的一端可以与第一枝节110的第一接地端1101相对并间隔设置。第三枝节113远离第一自由端1103的一端可以靠近第一枝节110的第一接地端1101，或者，第三枝节113远离第一自由端 1103的一端可以与第一枝节110的第一接地端1101相对并间隔设置。第一间隙部的尺寸与第二间隙部的尺寸可以相同也可以不同。第一间隙部的尺寸可以参照附图5中的L1，第二间隙部的尺寸可以参照附图5中的L2，以下实施例中第一间隙部直接描述为第一间隙部L1，第二间隙部直接描述为第二间隙部L2。第一间隙部L1、第二间隙部L2可以小于或等于第一天线辐射体11与第二天线辐射体12之间沿第一目标方向的间隔距离。可以理解的，第一枝节110的电流信号可传输至第二枝节112和第三枝节113。如此设置的第二枝节112、第三枝节113可用于调节第一枝节110的高阶谐振电流分布，降低第一天线辐射体11的交叉极化。
第二天线辐射体12与第一天线辐射体11沿第一目标方向间隔排布。第一目标方向可以参照附图4中的X轴方向，以下实施例中直接描述为第一目标方向X。第一目标方向X可以为电子设备100的宽度方向，此时，第一天线辐射体11和第二天线辐射体12沿第一目标方向X间隔排布形成水平测角天线组，可用于测量电磁波信号的到达角中的方位角。当然，在其他实施例中，第一目标方向X还可以为电子设备100的长度方向，此时，第一天线辐射体11和第二天线辐射体12沿第一目标方向X间隔排布形成垂直测角天线组，可用于测量电磁波信号的到达角中的俯仰角。第二天线辐射体12的材质为导电材质。举例而言：第二天线辐射体12的材质可以是金属、合金等。第二天线辐射体12用于电连接射频信号源。第二天线辐射体12与射频信号源之间的电连接方式可以包括直接电连接、间接电连接、耦合连接中的一种或多种。第二天线辐射体12用于获取射频信号源产生的电流信号。第二天线辐射体12可产生四分之一波长谐振模式或二分之一波长谐振模式。
本申请提供的天线组件1包括沿第一目标方向间隔排布的第一天线辐射体11和第二天线辐射体12，第一天线辐射体11与第二天线辐射体12形成二维测角天线组，可根据第一天线辐射体11与第二天线辐射体12接收电磁波信号的相位差，实现到达角的测量。而第一天线辐射体11包括第一枝节110、第二枝节112和第三枝节113，第二枝节112、第三枝节113分别位于第一枝节110的相背两侧，且第二枝节112、第三枝节113分别与第一枝节110的第一自由端1103相连，第二枝节112与第一枝节110之间形成第一间隙部L1，第三枝节113与第一枝节110之间形成第二间隙部L2，如图6所示，使得第二枝节112、第三枝节113可用于调节第一枝节110的高阶谐振电流分布，改善第一天线辐射体11的交叉极化，提高天线组件1的相位差曲线的收敛度，进而有利于提高测量到达角的精度。
进一步地，请参照图7和图8，天线组件1还包括第一馈线14。第一馈线14的一端电连接第一馈电点1102，第一馈线14的另一端电连接射频信号源。第一馈线14在第一天线辐射体11的所在面的正投影由第一馈电点1102朝向第一接地端1101的所在侧延伸，或者，第一馈线14在第一天线辐射体11的所在面的正投影由第一馈电点1102朝向第一自由端1103的所在侧延伸。其中，第一馈线14可以与第一天线辐射体11设于介质层10的同一表面，也可分别设于介质层10的正面和背面。当第一馈线14与第一天线辐射体11分别设于介质层10的正面和背面时，第一馈线14电连接第一天线辐射体11的第一馈电点1102的一端可以为导电过孔。第一馈线14的另一端可以包括微带线、同轴线、导电过孔、导电探针、导电弹片等。
通过使第一馈线14在第一天线辐射体11的所在面的正投影由第一馈电点1102朝向第一接地端1101的所在侧延伸，或者，使第一馈线14在第一天线辐射体11的所在面的正投影由第一馈电点1102朝向第一自由端1103的所在侧延伸，可以减小第一天线辐射体11在靠近第一间隙部L1所在侧的高阶谐振电流，减小第一天线辐射体11在靠近第二间隙部L2所在侧的高阶谐振电流，降低第一枝节110自身的交叉极化，提高天线组件1的测角精度。
可选的，第一间隙部L1的尺寸大于或等于0.2mm且小于或等于1.5mm。第一间隙部L1的尺寸越小，第一枝节110在第一间隙部L1所在侧的磁流越强，第一枝节110的交叉极化越小，进一步地提高天线组件1的测角精度。第二间隙部L2的尺寸大于或等于0.2mm且小于或等于1.5mm。同样的，第二间隙部L2的尺寸越小，第一枝节110在第二间隙部L2所在侧的磁流越强，第一枝节110的交叉极化越小，进一步地提高天线组件1的测角精度。
一实施例中，如图9所示，第二天线辐射体12为贴片天线辐射体。第二天线辐射体12的形状可以为圆形、椭圆形、三角形、方形、矩形、其他多边形以及各种异形等，本实施例中以矩形的第二天线辐射体12为例。本实施例中，第二天线辐射体12未直接接地，第二天线辐射体12本身的交叉极化较小，与第一天线辐射体11结合，可使得天线组件1整体的交 叉极化较小，进而提高天线组件1的相位差曲线的收敛度，有利于提高天线组件1进行测角的精度。
另一实施例中，如图10所示，第二天线辐射体12为平面倒F型天线辐射体。第二天线辐射体12包括第二馈电点1202和至少一个第二接地点120a。第二馈电点1202用于电连接射频信号源。举例而言，第二馈电点1202与射频信号源之间可以通过微带线、同轴线、探针、弹片等进行电连接。至少一个第二接地点120a用于电连接参考地。本申请对于第二接地点120a的数量不作具体的限定。举例而言，第二接地点120a的数量可以为一个、两个、三个、五个、八个、十个等，当第二接地点120a的数量为多个时，多个第二接地点120a可以沿特定方向依次排列。可选的，至少一个第二接地点120a电连接电子设备100的外壳21，或者，至少一个第二接地点120a电连接电子设备100的电路板22的接地层。至少一个第二接地点120a与参考地之间可以通过微带线、同轴线、探针、弹片等进行电连接。本实施例中，第二天线辐射体12的频带宽、体积小，在实现测角的同时有利于拓宽天线组件1的带宽和实现天线组件1的小型化。
再一实施例中，请参照图11和图12，第二天线辐射体12包括第四枝节120和分别位于第四枝节120相背两侧的第五枝节121、第六枝节122。换言之，第五枝节121、第四枝节120以及第六枝节122依次排列。其中，第四枝节120的材质、第五枝节121的材质以及第六枝节122的材质皆为导电材质。举例而言：第四枝节120的材质、第五枝节121的材质以及第六枝节122的材质可以为金属、合金等。第四枝节120的材质、第五枝节121的材质以及第六枝节122的材质可以相同也可以不同。
