在本文中提及“实施例”或“实施方式”意味着，结合实施例或实施方式描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
需要说明的是，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。
在对本申请提供的电子设备进行介绍之前，先介绍超宽带(Ultra Wide Band，UWB)技术的天线的测角原理。请参阅图1，图1为电子设备利用UWB天线收发电磁波信号时的示意图。在本示意图中，以P 1点表示第一天线20(参阅图2-图5)中的一个第一辐射体，以P 2点表示第一天线20中另一个辐射体，以P 3点表示电磁波信号过来的位置；P 4点表示P 1和P 2连线的中点。在本实施方式中，θ 1表示P 1P 2连线与P 3P 1连线之间的夹角；θ 2表示P 1P 2连线与P 3P 2的连线之间的夹角；θ表示P 1P 2的连线与P 3P 4的连线之间的夹角；α表示θ的余角；D表示P 3P 4之间的距离；λ表示第一天线20及第一天线20收发的电磁波信号的波长；f表示第一天线20收发的电磁波信号的频率；d max表示第一天线20的两个第一辐射体的间距的最大值。
其中，D远大于λ，则有θ 1≈θ 2≈θ。
由于所述第一天线20为利用UWB技术的天线，即所述第一天线20为UWB天线，因此：
f的范围为6.25GHz～8.25GHz；
相应地，
λ的范围为36.4mm～48mm，则有：
λ/2的范围为18.2mm～24mm。
d max＝18mm；
d 1＝d cos θ＝d sin α    (1)
电磁波信号达到第一天线20的一个第一辐射体和第一天线20中另一个第一辐射体的时间差t 1为：
Figure PCTCN2022140195-appb-000001
其中，c表示光速，由于t 1表示电磁波信号达到第一天线20的一个第一辐射体和第一天线20中另一个第一辐射体的时间差，因此，也称为到达时间差(Time Difference of Arrival，TDOA)。
电磁波信号达到第一天线20的一个第一辐射体和第一天线20中另一个第一辐射体的相位差
Figure PCTCN2022140195-appb-000002
为：
Figure PCTCN2022140195-appb-000003
由于
Figure PCTCN2022140195-appb-000004
表示电磁波信号达到第一天线20的一个第一辐射体和第一天线20中另一个第一辐射体的相位差，因此，也称为到达相位差(Phase Difference of Arrival，PDOA)。
Figure PCTCN2022140195-appb-000005
其中，α表示达到角度(Angle of Arrival，AOA)。由(4)可见，到达角度(AOA)α和到达相位差(PDOA)
Figure PCTCN2022140195-appb-000006
相关。
综上所述，本申请实施方式提供的电子设备中第一天线的测角原理为：对于不同方向的入射的电磁波信号，到达电子设备中的第一天线中两个第一辐射体的路径不同，因此，引入了路径差，从而引入了到达时间差(TDOA)，从而引入了到达相位差(PDOA)
Figure PCTCN2022140195-appb-000007
通过到达相位差PDOA和到达角(AOA)α之间的唯一函数关系(4)可实现测角。
工业和信息化部关于UWB天线的使用的规定为UWB天线的发射信号的等效全向辐射功率频谱密度限值在6GHz-9GHz时为-41dBm/MHz。由此可见，这个规定限制了UWB天线的发射功率，因此，UWB天线较高的方向性会导致测距均匀不佳，具体表现在UWB天线在增益强的方向测距远，在增益弱的方向测距短。为了提高UWB天线的通信距离，有必要引入低方向性甚至全向性的UWB天线。相较于定向天线而言，全向性的UWB天线的测距和测角效果更好。

在本实施方式中，所述多个第一辐射体220承载于所述支架10的周侧壁120上，且设置于所述周侧面10c。换而言之，所述多个第一辐射体220均匀环绕于所述支架10的周侧面10c。可以理解地，在其他实施方式中，所述多个第一辐射体220也可以设置于所述周侧面10c之外的其他地方，比如，内嵌于所述周侧壁120，或设置于所述周侧壁120中与所述周侧面10c相背设置的内壁面。本申请对所述多个第一辐射体220承载于所述支架10的形式不做限定。
所述第一辐射体220可以为但不仅限于为激光直接成型(Laser Direct Structuring，LDS)辐射体，或者，柔性电路板(Flexible Printed Circuit，FPC)辐射体，或者印刷直接成型(Print Direct Structuring，PDS)辐射体、或者为金属枝节辐射体。
所述第一辐射体220的数目与所述传输部212的数目相等，每个第一辐射体220均与一个传输部212电连接，且不同的第一辐射体220电连接不同的传输部212。当所述第一天线20用于发射电磁波信号时，所述第一辐射体220接收所述传输部212传输的所述射频信号，并根据所述射频信号产生预设频段的电磁波信号。所述第一天线20为UWB技术的天线，因此，所述第一辐射体220产生的信号也为UWB信号。所述UWB技术的第一天线20不是采用载波，而是采用纳秒至微秒级的非正弦波窄脉冲传输数据，因此，所占的频谱范围较宽，适用于高速、近距离通信。美国联邦通信委员会(Federal Communications Commission，FCC)规定，UWB技术的天线的工作频段范围从3.1GHz到10.6GHz，最小工作频宽为500MHz。目前主流的UWB技术的天线收发预设频段的电磁波信号时的中心频点为8GHz或者为6.5GHz。
在本实施方式中，所述多个第一辐射体220均匀环绕所述传输件210设置。换而言之，每个第一辐射体220与所述传输件210之间的距离相同，且相邻的两个第一辐射体220之间的间隙相同。所述多个第一辐射体220均匀环绕所述传输件210设置，从而使得所述多个第一辐射体220上形成相对均匀的圆形电流，进而实现较好的全向辐射。可以理解地，所述多个第一辐射体220排布的均匀性越好，所述多个第一辐射体220上越能够形成相对均匀的圆形电流，所述第一天线20的全向性越好。反之，所述多个第一辐射体220排布的均匀性越差，所述多个第一辐射体220上则不能够形成相对均匀的圆形电流，所述第一天线20的全向性越差。可以理解地，在其他实施方式中，所述多个第一辐射体220非均匀环绕所述传输件210设置，这种情况下，虽然所述第一辐射体220的全向性相对差点，但，主要满足所述第一天线20能够形成全向天线即可。
综上所述，本申请实施方式提供的电子设备1中第一天线20包括多个第一辐射体220，且第一辐射体220环绕设置，以使得所述第一天线20形成为全向水平极化天线。因此，所述第一天线20的方向性较低，全向性较好，当所述电子设备1利用所述第一天线20进行测距及测角时，测量效果较高。

在本实施方式的示意图中，以所述至少一个寄生辐射体230为4个，且以所述第一辐射体220为4个为例进行示意，每个寄生辐射体230均设置于相邻的两个第一辐射体220之间为例进行示意，可以理解地，不应当构成对本申请提供的电子设备1的限定。在其他实施方式中，所述至少一个寄生辐射体230也可以为一个，两个，三个，五个，六个甚至更多个。所述至少一个寄生辐射体230的数目可以与第一辐射体220的数目相同，也可以与所述第一辐射体220的数目不相同。任意两个相邻的第一辐射体220之间的寄生辐射体230的数目可以相同，也可以不相同。当然，在一种实施方式中，在一对相邻的两个第一辐射体220之间存在寄生辐射体230，在另一对相邻的第一辐射体220之间不存在寄生辐射体230。在另一种实施方式中，当两对相邻的第一辐射体220之间都存在寄生辐射体230时，其中的一对相邻的第一辐射体220之间的寄生辐射体230的数目可以与另一对相邻的第一辐射体220之间的寄生辐射体230的数目相同，也可以不相同。当两对相邻的第一辐射体220之间都存在寄生辐射体230时，其中的一对相邻的第一辐射体220之间的寄生辐射体230的数目可以与另一对相邻的第一辐射体220之间的寄生辐射体230的数目相同，换而言之，相邻的两个第一辐射体220之间设置有同等数目的寄生辐射体230。当相邻的两个第一辐射体220之间设置有第一辐射体220时，相邻的两个第一辐射体220的数目可以为一个，也可以大于或等于一个。综上所述，所述寄生辐射体230的设置方式多种多样，只要满足所述第一天线20中包括寄生辐射体230，所述寄生辐射体230设置于相邻的两个第一辐射体220之间，且和所述相邻的两个第一辐射体220中的至少一个耦合即可。

请参阅图35，图35为图8中所示的电子设备中的第一天线中的方向示意图。由此可见，由此可见，所述第一天线20的水平方向图接近一个圆，所述第一天线20的全向性较好，因此，在水平方式上的测距均匀性较好，具有较强的工程实用性。
请参阅图36，图36为图8中所示的电子设备中第一天线的方向性示意图。在本示意图中，横坐标为频率，单位为GHz；纵坐标为方向大小，单位为dBi。由此可见，所述第一天线20的方向性在CH9频段大部分都小于3dB，最小接近2.4dB，方向性很低，相应地，所述第一天线20的全向性较好。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
